Results: Age range of the patients with leiomyoma was18-62 years. The so-called solid type can also be relatively coarse in comparison. Benign tumors were more common than malignant tumors. The uterine variant typically arises during pubescence. Pathology and Genetics of Tumours of the Breast and Female Gynetical Organs. PEComa can be ruled out on the basis of HMB45 negativity (58). Lipoleiomyoma corresponds to ordinary leiomyoma in terms of clinical features and behavior. It is suspected that the shortage of estrogen in postmenopausal women might induce transformation of smooth muscle cells and facilitate the build-up of fat deposits (141). While the cystic components revealed in diagnostic imaging are suggestive of ALM, they are usually a sign of LM degeneration. It appears to develop from the smooth musculature of the veins. (5th ed), vol.2, New York: Churchill Livingstone 2003. Organ-sparing operations should, therefore, only be performed upon critical deliberation, and should leave no microscopic residual disease. In another case, a cotyledonoid LM was excised completely at 14 weeks of gestation, and cesarean section to term revealed that the uterus was disease-free (152). The most common symptom was postmenopausal bleeding (76.9%). Three neoplasms contained cells with abundant foamy cytoplasm that were immunoreactive for CD68, indicating that they were histiocytes and not neoplastic cells. The presence of ample dilated vessels renders ALM relatively soft compared to ordinary uterine LM, and elastic like rubber. They can literally fill the entire lower abdomen, and occasionally be equivalent in size to 40 weeks’ gestation (84, 88, 129, 222). These tumors show high heterogeneity in several aspects such as size, location and symptoms and represent the current major cause of hysterectomy. PEComa, Vol. women. In contrast to the suspicious clinical and macroscopic findings, the risk of mistaking ALM with sarcoma in histology is low. Uterine corpus tumors are one of the most common reasons for morbidity and mortality of women around the world, and histopathological diagnosis is the key for better management of the patients. Adenomyosis was associated with leiomyoma in 19.23% cases. France: IARC Press Cutaneous pilar leiomyoma, arising from arrector pili muscle; 2. Other lesions were adenomyoma (N = 17), STUMP (N = 2), and one case each of adenomatoid tumor, endometrial stromal nodule and secondary tumor. In general, given the unusual growth pattern of these tumors, recurrences need to be reckoned with when conservative surgery is opted for. HE constitutes the therapeutic measure of choice. Strongly vascularized tumors also clearly present as such in sonography when localized in the ligamentum latum (44). R0 resection is the method of choice when there is extrauterine spread. Until additional evidence has been accumulated it is proposed that neoplasms having five or more mitotic figures per ten high-power fields (HPF) be tentatively termed epithelioid leiomyosarcoma or leiomyosarcoma with epithelioid features and those with less than five mitotic figures per ten HPF, epithelioid leiomyoma. Leiomyoma was the most common benign tumor, and endometrial carcinoma was the most common malignant tumor. World Health Like ordinary LM, ALM can reach enormous dimensions. Angyoleiomyoma, arising from vessel walls 3. Orv. Clinically malignant tumors (i.e., epithelioid leiomyosarcomas) typically have the combination of significant nuclear atypia (either grade 2 or grade 3 nuclei) and some mitotic activity (usually at least 3 to 4 MF/10 HPF); most also have tumor cell necrosis. Günter Köhler, Katja Evert, Marek Zygmunt and Matthias Evert. France: IARC Press Furthermore, ALM have clinical features that are suggestive of malignant behavior, but do not fulfill the malignancy criteria. 1.1.1 (A)), sometimes pink to yellowish macroscopic appearance. CT often reveals a heterogeneous lobulated mass that can contain both solid and cystic components. Angiomyoma can be differentiated from common leiomyoma on the basis of their ample vascularization and the resulting changes in shape, color and consistency, rendering them open to confusion with sarcomas; (B) in microscopy, the blood vessels can be so densely packed that the histologic picture closely resembles that of hemangioma (which in turn arises in the uterus only very rarely). The borders between these two components can be irregular, i.e. Infarction-type necrosis was seen in 3 cases, and a coagulation-type necrosis was seen in 2 cases of … the components can exhibit a certain degree of “blending” (84, 91, 100). World Health Organization of Tumours. The PET-CT shows no increase of activity (91). In native CT and CECT, the adipocytic accumulations are recognizable, both natively and within the enhancing LM, on the basis of their weaker attenuation (191). The specimens were properly labeled, fixed (in NBF), examined grossly, processed, stained and examined microscopically. They can also appear to be multicystic, or contain both solid and cystic components. Only morphologic variants of leiomyoma (cellular leiomyoma, leiomyoma with bizarre nuclei, etc. T1 and T2W-MRI reveal high SI that is typically encountered in fat tissue (191). Conclusion: Variants of leiomyomas were relatively less, but it is important to differentiate them from malignant neoplasms of the myometrium, as they have good prognosis. Cellular leiomyoma (1.8%) was the most common histologic variant; the secondary change was hyalinization (27.8%). Malignant tumor of the myometrium was diagnosed in one hysterectomy specimen out of 1,845 specimens. Atypical leiomyoma: This lesion likely falls on a spectrum between leiomyoma and leiomyosarcoma. Some researchers believe that a degenerated ULM can turn into a ULMS; others claim that ULMSs can only arise de novo. Majority of the patients were between 41-50 years (46.84% cases). Other variants are defined by their capacity to spread to other organs without invasion, and thus remains histologically benign. Conclusion The most location was intramural (68.9%). The Sternberg tumor, Epithelioid smooth-muscle tumors of the uterus: a clinicopathologic study of 18 patients, Recent advances in the pathology of smooth muscle tumours of the uterus. It is very effective in differentiating ALM from malignant tumors. The solid tissue was frequently yellow. Reresection/completion surgery should, therefore, be considered in cases in which there is microscopic or macroscopic residual tumor. Ten tumors had grade 2 nuclei. This report provides a clinical presentation, and histologic descriptions of the two variants of leiomyomas that have not been reported in veterinary medicine. DPLM, IVLM or parasitic LM are further possible DD. Keywords: Dicerorhinus sumatrensis; Sumatran rhinoceros; WG, Haller U, Kubik-Huch RA. DLM can bear close gross resemblance to ALM in terms of consistency and color. Leiomyoma is a rare, smooth muscle tumour that can occur everywhere in the human body. There is a broad spectrum of leiomyoma variants: some have a single histologic finding that is associated with leiomyosarcoma, such as an increased mitotic index or severe cytologic atypia, while other growth pattern variants are defined by their capacity to spread to peritoneal surfaces or solid organs but are histologically benign. In T1WC, cotyledonoid dissecting LM shows strong enhancement with minimal heterogeneity, as do neighboring LM. The large amount of blood can “mimic” rapid growth, cause pains in the lower pelvis and justify a suspected diagnosis of sarcoma. Growth beyond the uterus into the ligamentum latum is frequently observed (121, 187, 204). In: Tavassoli FA, Deville P (Eds). Referral for genetic counselling and testing should be considered in a young patient with uterine leiomyomas showing FH-d morphology even if immunohistochemical staining for FH is retained. Hereditary leiomyomatosis and renal cell carcinoma syndrome (HLRCC), caused by a germline mutation in the fumarate hydratase (FH) gene, predisposes patients to uterine and cutaneous smooth muscle tumors and an aggressive type of renal cell carcinoma. Majority of the patients were between 41-50 years (46.84% cases). There are ample noticeable signal voids that correspond to the high degree of vascularity (203). Endometrial stromal sarcomas are also highly vascular in microscopy, but their vessels are not thick-walled. CONCLUSIONS: Accurate knowledge of these variants and degenerative changes in leiomyomas are mandatory to prevent misdiagnosis and over treatment along with undue stress to the patient. Tumor size, nature of margin, presence or absence of vascular invasion, coagulative necrosis and cytological atypia are the most important histological features for differentiation. All patients were found to have been taking a combination-type oral contraceptive hormonal medication containing the progestin norethindrone for 2-4 years. Obstetrical and Gynaecological Pathology CLINICOPATHOLOGICAL STUDY OF UTERINE LEIOMYOMAS IN HYSTERECTOMY SPECIMENS; A RETROSEPTIVE STUDY. Conclusion: Accurate knowledge of these variants and degenerative changes in leiomyomas are mandatory to prevent misdiagnosis and over treatment along At laparotomy, an exophytic congested bulky tumor resembling placental tissue extended from the uterine wall into the broad ligament and pelvic cavity. Cutaneous leiomyoma is a rare, benign, smooth muscle tumor. Fig. Leiomyomas are composed of bundles of smooth muscle cells that look very much like those of the normal myometrium. The solid structures thus correspond to the MRI picture of LM. However, the distribution and topography of FH-d morphology and FH loss by IHC in the context of multiple leiomyomas in patients with HLRCC has not been evaluated. They had highest mitosis counts of 1 and 3 mitotic figures (MF)/10 high-power fields (HPF), no tumor cell necrosis was found, and both patients were alive with no evidence of disease at 64 and 5 months' follow-up. Since ALM are without doubt benign, patients can also undergo conservative, uterus-sparing surgery. In diagnostic imaging, both sonography and MRI reveal numerous voids, which correspond to vessels, within the typical leiomyoma picture. The solid structures exhibit the MRI characteristics of LM. However, there are no clinical findings that can clearly differentiate these neoplasms [10. In one case the tumors were bilateral but unequal in size. Degenerative changes were observed in 16.46% cases, amongst which hyaline change was the most common (6.33%). They are noted clinically in 20-30% of women over 30 years of age; are rare prior to the menarche, common in reproductive life and have a tendency to regress after the menopause. (ABSTRACT TRUNCATED AT 400 WORDS). Mesenchymal tumours and Like ordinary LM, multiple ALM can arise synchronously. Methods: In this prospective study, 1,845 hysterectomy and myomectomy specimens collected over a period of two years were studied. Epithelioid variants have been described (32). Leiomyoma was the most common tumor of the myometrium constituting 99.54%. There are a number of leiomyoma variants in which the smooth muscle neoplasm manifests one histologic facet typical of malignant neoplasm, yet lacks others. Necroses, mitoses and atypia are usually not observed, and when they are, they do not account for a substantial share of the tumor’s total volume (Fig. Women are noticeably more frequently affected than men are. 9 types of leiomyoma variants were seen, amongst which cellular leiomyoma (6.33%) was the commonest. A focal fascicular pattern was present in all of the cases. One patient had also received adjuvant radiation therapy. In one case, a patient in whom a superficial tumor had been incompletely resected gave birth via cesarean section after an uneventful pregnancy. In conclusion, patients with HLRCC undergo surgery at young ages for highly symptomatic uterine leiomyomas. Usual leiomyoma constituted for 95.45% and variants of leiomyomas were 4.55%. LLM can also arise in the vicinity of the ligamentum latum (260). Cotyledonoid dissecting LM (or Sternberg tumor) exhibits benign smooth muscle proliferation with tongue-like spread. Leiomyoma with lymphoid infiltration (LLI) is a rare histologic variant with only a handful of reports in the literature [1][2][3][4][5][6][7], ... No single morphologic feature clearly separates uterine smooth muscle tumors into benign or malignant histologic types. Prevention of inadequate sarcoma operations, Endometrial stromal tumors – endometrial stromal nodule, endometrial stromal tumor with sex cord-like elements (ESTSCLE), uterine tumor resembling ovarian sex-cord tumor (UTROSCT) and similar tumors, High-grade endometrial stromal sarcoma and undifferentiated uterine sarcoma, Deep Dry Needling of the Shoulder Muscles, Smooth Muscle and Stromal Tumors and Prevention of Inadequate Su. Bleeding can be ample in the course of surgery, rendering endoscopic procedures rather inadequate. Two had tumor cell necrosis, and two had an infiltrative border. LLM have an average diameter of 4.6 cm. After examination the authors removed the soft tissue mass in the right femoral region reaching down in supine position to the middle third of the leg measuring 335 × 495 × 437 mm in greatest diameters in weight 33 kg. Angioleiomyoma is a benign variant of leiomyoma and is very rare. In summary, the simultaneous presence of cystic and solid structures is the decisive feature in imaging diagnostics. Two of these patients died of tumor 11 and 132 months postoperatively. WG, Haller U, Kubik-Huch RA. To investigate the differences in leiomyoma pathophysiology by patient age at the time of surgery and the possible significance of postmenopausal uterine leiomyomas, particularly variants. All patients were of reproductive age, ranging from 23 to 41 years old, and had a pelvic mass or an enlarged uterus. The same applies for primary or neoadjuvant CHT and/or RT in generally inoperable cases. Features related to a favorable prognosis include the presence of clear cells, an expansile tumor margin, extensive hyalinization, and absence of extensive necrosis as seen microscopically. Intratumoral bleeding with clotting occasionally results in consumptive coagulopathy (88). Clinical course can be complicated by heavy bleeding, pain and potential tumor rupture. Only two cases have been reported in which local recurrence developed after surgery on extragenital ALM, though no mention is made of the surgical procedures applied (82). Continuous growth with uncontrollable AUB were observed in a case of a patient who underwent incomplete surgery (210). The most common variant of leiomyoma was cellular leiomyoma while hyaline degeneration was the most common secondary change identified. Lipoblasts, mitoses and atypia are absent (see also Tab. The aim of this study is to describe in detail the clinical and pathologic characteristics of uterine leiomyomas from women with HLRCC. Some histological features may be important to differentiate the leiomyoma variants from uterine ULMSs: tumor size, cytological atypia, presence or absence of vascular invasion, coagulative necrosis, and tumor margin. Five tumors were entirely well circumscribed and one predominantly well circumscribed with limited extension into the adjacent myometrium. of the Breast and Female Gynetical Organs. Cotyledonoid leiomyoma is a benign tumor. The tumors ranged in size from about 1.1 to 4 cm and had multiple gross hemorrhages. Temporary treatment with GnRH analogues can, therefore, be adequate for bridging the time until surgery or impending menopause. In a recent study, applying the AI letrozole (2.5mg over 3mo) to premenopausal LM patients (aged 30–55 years) achieved a tumor volume reduction of > 50% and significant symptomatology improvements (63). METHODS This prospective study consists of 1,845 hysterectomy and The patients usually presented with irregular uterine bleeding. Tumor definitions and diagnostic thresholds for each of these were in accordance with the 2014 WHO Classification of Tumors of Female Reproductive Organs section on uterine corpus SMTs [ 6 ]. The former had widespread metastases at initial surgery (stage IVb); the latter patient (stage I) developed the first of seven tumor recurrences 3 years postoperatively. Pedunculated subserosal ALM can reach considerable dimensions and are barely discernible from mobile ovarian tumors on palpation (84). The tumor is characterized by a stroma with mediate collagen levels. © 2008-2021 ResearchGate GmbH. Leiomyoma was the most common tumor of the myometrium constituting 99.54%. Cutaneous pilar leiomyoma usually presents as multiple tumors and, though sporadic in the vast majority, a familial autosomic dominant pattern of inher… FH-d morphology was present in leiomyomas from all patients and was typically observed as a diffuse finding in the majority of slides across different leiomyoma types. Based on our findings and those in the literature, we conclude that uterine smooth-muscle tumors with a predominance of epithelioid cells are extremely uncommon and metastasize infrequently. The Uterine corpus. Affected women frequently have disorders in their fat-related metabolism and are often heavy by comparison. A retrospective follow-up study of 18 uterine epithelioid smooth-muscle tumors was performed. Fat tissue can account for strongly varying shares of total tumor volume (. Lippincott, Williams and Wilkins 2004. Leiomyoma is the commonest benign neoplasm affecting uterus of females in the reproductive age group. stopping bleeding. Recognition of their distinctive pathologic features will prevent misdiagnosis as leiomyosarcoma. Malignant tumor of … The spindle cells are positive for SMA, desmin, vimentin, caldesmon, ER and PGR (36, subserosal ALM can reach considerable dimensions and are barely discernible from mobile ovarian tumors on palpation (84). In the majority of cases, ALM are subjected to further diagnostics because of (hyper)menorrhagia or a “rapidly growing uterus”. Cotyledonoid dissecting leiomyoma is accompanied by symptoms comparable to those of ordinary leiomyoma. Several studies have focused on the molecular mechanisms of these tumors; however, no specific marker or signaling has been defined for clinical and therapeutic applications. 2003. May be treated medically with a selective progesterone receptor modulator, e.g. LLM are relatively soft tumors with a whitish-yellowish color on the cut surface. Uterine leiomyomas are common benign tumors of the myometrium. Atypical leiomyoma of the uterus: A case report Sweta Singh, Monalisha Naik, Jagadish Chandra Behera, Pritinanda Mishra, Mamita Nayak ABSTRACT Introduction: Leiomyoma of the uterus is the most common tumor of the female reproductive tract. They give the tumor a placenta-like appearance. Congracre TA, Kempson RL (Eds). 56.96% leiomyoma’s were single and 43.04% were multiple. Sonography reveals a well-circumscribed uterine mass with heterogeneous echogenicity, solid components and numerous anechoic voids that correspond to vessels (58, 91, 100). All 6 patients presented with symptomatic uterine fibroids and underwent myomectomy (age 24 to 36 y), followed by hysterectomy in 2 patients (age 31 and 40 y). These macroscopic features often give the impression of a malignant tumor. On microscopic examination the basic lesion appeared to be a dissecting leiomyoma with growth at its periphery in sinuous dissecting patterns and extensive degenerative changes. No single histologic feature is predictive of metastatic potential. To help better The various hypotheses which have been proposed to explain the etiopathogenesis include reactive alterations due to intrauterine pessaries, hormonal therapy or immune response dysregulation.Case report: We hereby report a case of a 44 year old female who presented with abnormal uterine bleeding. Like ordinary leiomyoma, angioleiomyoma is a benign tumor. Twenty-six cases of atypical smooth muscle tumors of the uterus, including leiomyoblastoma, epithelioid leiomyoma, clear-cell leiomyoma, and plexiform tumorlet, are presented. 03 No. Blood vessels were typically large; thick muscular walls and focally dilated lumens were a conspicuous feature of the majority of the neoplasms. All tumors were immunoreactive for desmin and 32 of 32 for alpha-smooth muscle actin. The solid components show strong enhancement in T1WC (91). 2003. FH-d morphology was absent in some leiomyoma sections from one patient and the morphologic features were focal and subtle in leiomyomas from 2 patients. Combined with the edemas and vessels, the tumor’s dark-red color and sponge-like structure render it similar to placental cotyledons when it has spread beyond the uterus (hence the name). Five histologically distinctive uterine smooth muscle neoplasms with multifocal hemorrhages termed apoplectic leiomyomas were studied. 1.9.1). The same applies for primary and neoadjuvant CHT and/or RT in generally inoperable cases. Constituting a variant of LM, the “International Classification of Diseases for Oncology” deems LLM benign and codes it with “0” (183). However, the proper diagnosis is only rarely reached preoperatively, even when there are typical symptoms. FH-deficient uterine leiomyomas can show characteristic morphologic features (FH-d morphology) that have been previously described. 1.1.1 (B)). Cotyledonoid dissecting leiomyoma is characterized by benign smooth muscle proliferation with tongue-like extensionwithin the myometrium. All had highest mitosis counts of 0 to 3 MF/10 HPF, except one (5 MF/10 HPF). The authors present the history of a 60-year-old female, who had a giant, Mullerian type myxoid leiomyoma in the inguinal region mimicking acute abdominal symptoms. Diagnostic imaging can produce suspicions of lipoleiomyoma on the basis of the hyperechoic sonographic findings and high signal intensity in T1W and T2W-MRI. In: ALM are histologically differentiated into the solid/capillary, cavernous and venous subtypes. Microscopically, they were characterized by stellate zones of recent hemorrhage within nodules of hypercellular smooth muscle. We report four cases of an unusual uterine smooth muscle neoplasm. As a variant of LM, the “International Classification of Diseases for Oncology” deems such tumors benign and codes them with “0” (183). 1.2.1: Histologic aspect of a lipoleiomyoma. The coincidence of a uterine tumor and rapid growth can arouse a suspicion of uterine sarcoma, not least because the latter also have a softer consistency than ordinary LM. Their gross appearances are often altered by various secondary changes. As is the case for all adipocytic tumors, sonography reveals more or less expansive hyperechoic areas in an otherwise hypoechoic uterine mass (191). These suspicious clinical findings can lead to (even intraoperative) confusion with a malignant mesenchymal tumor. Since the definitive diagnosis cannot be made on the basis of clinical criteria alone, the unusual appearance of ALM should give rise to intraoperative histologic clarification via frozen section. On gross examination, these exophytic components were the most distinctive feature. Background: Myometrial lesions form a diverse group amongst which leiomyoma is the commonest visceral neoplasm affecting females in the reproductive age group. ... 3 The incidence of these changes and variants are similar to other publications where a large number leiomyomas were studied. THE is the standard surgical procedure. Subserosal ALM can develop extraperitoneally into the ligamentum latum or the abdominal cavity via pedicular growth, and clinically mimic a solid, relatively soft adnexal tumor (. Angioleiomyomas (Vascular leiomyomas) that are thought to arise from vascular smooth muscle. One striking feature of ALM is its ample degree of vascularization. The symptoms of and findings for uterine angioleiomyoma largely correspond to those of ordinary leiomyoma. RESULTS: The most common variant of leiomyoma was cellular leiomyoma while hyaline degeneration was the most common secondary change identified. Age range of the patients with leiomyoma was 18-62 years. Benign tumors were diagnosed in 440 cases, and all the benign tumors were leiomyomas except one case of adenomyoma. ALM are also microscopically well-delineated from their surroundings. A small intramural leiomyoma was found which on pathological examination turned out to be leiomyoma with lymphoid infiltration.Conclusions: The importance of recognition this peculiar histological variant is to avoid possible misinterpretation as malignant lymphoma, inflammatory pseudotumororpyomyoma. Objectives: To know the incidence of leiomyoma in hysterectomy specimens and study the degenerative changes of leiomyoma and its variants. Immunohistochemistry (IHC) for FH can also be helpful in detecting FH deficiency in leiomyomas, which manifests as complete loss of staining for FH. Majority of the women with endometrial carcinoma were multiparous (76.9%) and belonging to the age-group of 50–59 years (38.4%). Methods: All the hysterectomy and myomectomy specimens which were received in the department of pathology, ASCOMS hospital Jammu, Jammu and Kashmir over a period of one year, out of which 79 cases with leiomyomas were included in the study. No recurrences developed up to 12 years after operation. T2W-MRI reveals a tumor with both hyperintense fluid-filled and solid hypointense areas that correspond to the smooth musculature. Mixtures of epithelioid, clear-cell, and plexiform patterns occurred with sufficient frequency to indicate that such patterns are variants of a single entity. As myoma variants are rare, it is undoubted that myoma variants of the cervix are extremely rare. `` symplastic '' ) multinucleated giant cells similar to other variants of leiomyoma where a large ALM in terms of symptomatology.
