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. Sonography reveals a well-circumscribed uterine mass with heterogeneous echogenicity, solid components and numerous anechoic voids that correspond to vessels (58, 91, 100). There is no indication for BSO. Thus, in both the clinical and pathological settings, it can be difficult to distinguish from leiomyosarcoma. Benign tumors were diagnosed in 440 cases, and all the benign tumors were leiomyomas except one case of adenomyoma. Organization of Tumours. Degenerative changes were observed in 16.46% cases, amongst which hyaline change was the most common (6.33%). Majority of the patients were between 41-50 years (46.84% cases). Tumors with a pronounced vascular component consisting of arteries, veins or undefinable vessels are referred to as angiolipoleiomyoma (275). Abstract. Growth beyond the uterus into the ligamentum latum is frequently observed (121, 187, 204). 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. Pathogenesis of this entity is not very clear. Hysterectomy is the standard surgical method, though strong intraoperative bleeding must be reckoned with. On gross examination, these exophytic components were the most distinctive feature. Compared to malignant ovarian tumors, however, ascites is absent and CA-125 values are not elevated in ALM (, In contrast to the very rare uterine ANS (see also ANS, Vol. It has been divided into different subtypes according to the skin structures from which it can derive: 1. METHODS This prospective study consists of 1,845 hysterectomy and At laparotomy, an exophytic congested bulky tumor resembling placental tissue extended from the uterine wall into the broad ligament and pelvic cavity. 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 event that a certain amount of time needs to be bridged until surgery can be performed, analogous to ordinary LM, there is currently no reason not to administer GnRH analogues or UPA as a means of symptom control, i.e. PEComa can be ruled out on the basis of HMB45 negativity (58). France: IARC Press Like ordinary LM, ALM can reach enormous dimensions. The spindle cells are positive for SMA, desmin, vimentin, caldesmon, ER and PGR (36, 58, 84, 91, 154). To study the histopathology of uterine tumors, classify them as per WHO 2014 classification and correlate with clinical parameters. ALM are histologically differentiated into the solid/capillary, cavernous and venous subtypes. In T1WC, cotyledonoid dissecting LM shows strong enhancement with minimal heterogeneity, as do neighboring LM. However, SI is slightly higher than in ordinary LM (152, 224). All patients were found to have been taking a combination-type oral contraceptive hormonal medication containing the progestin norethindrone for 2-4 years. ALM largely correspond to LM in terms of clinical symptomatology and findings, though there are some noteworthy particularities. Mesenchymal tumours and There is no indication for any type of adjuvant therapy. The specimens were properly labeled, fixed in formalin, examined grossly, processed, stained and examined microscopically. Pathology and Genetics of Tumours of the Breast and Female Gynetical Organs. Cavernous and venous ALM are characterized by strongly dilatated vascular spaces with narrow media and the ample presence of vessels with thick muscular walls (82, 117). Once the proper diagnosis has been reached, further surgical treatment should be performed according to the criteria for LM surgery. There are also known accounts of entirely extrauterine growth (152, 215). While most leiomyomas on histology are usual myomas, sometimes rare variants may be encountered. Blood vessels were typically large; thick muscular walls and focally dilated lumens were a conspicuous feature of the majority of the neoplasms. 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. A retrospective follow-up study of 18 uterine epithelioid smooth-muscle tumors was performed. Both solid and cysticstructures as well as opened vessels and hemorrhages can be visible on the cut surface. Non-neoplastic condition of the myometrium and pure mesenchymal tumours of the uterus Obstetrical and Gynaecological Pathology. Cutaneous pilar leiomyoma usually presents as multiple tumors and, though sporadic in the vast majority, a familial autosomic dominant pattern of inher… Both patients had also received adjuvant chemotherapy. In addition, despite of the MRI recommendation as better technique for LMS and LM differentiation, none image method still present sufficient sensitivity for their preoperative diagnosis. The treatment of choice is a surgical removal of the entire tumor. Atypical leiomyoma: This lesion likely falls on a spectrum between leiomyoma and leiomyosarcoma. ALM often appear as heterogeneous lobulated tumors in CT. Cotyledonoid leiomyoma is a benign tumor. 1.1.1: (A) angiomyoma – vaginal hysterectomy with morcellation under the preoperative diagnosis of ordinary leiomyoma. DPLM, IVLM or parasitic LM are further possible DD. (ABSTRACT TRUNCATED AT 400 WORDS). © 2008-2021 ResearchGate GmbH. 1.1.1 (A)), sometimes pink to yellowish macroscopic appearance. Secondary changes were observed in 24.2% cases and histological variants comprised 7.5% of the cases. Accordingly, tumors vary considerably in size, ranging from 4 to 41 cm, with a mean widest diameter of 14.2 cm. Cutaneous pilar leiomyoma, arising from arrector pili muscle; 2. On gross examination, these exophytic components were the most distinctive feature. Reresection/completion surgery should, therefore, be considered in cases in which there is microscopic or macroscopic residual tumor. 2 variants of leiomyoma, 1 case of cellular leiomyoma and other case of mitotically active leiomyoma were found. France: IARC Press Furthermore, ALM can be submucously, intramurally and subserosally localized. THE is the therapeutic measure of choice. Background: Uterine leiomyomas are common tumours of the female genital tract and may be responsible for significant morbidity. (5th ed), vol.2, New York: Churchill Livingstone 2003. Highest mitosis counts of 4 to 9 MF/10 HPF were found in five; one had 1 MF/10 HPF. Two tumors contained pleomorphic ("symplastic") multinucleated giant cells similar to those seen in bizarre leiomyomas. The symptoms of and findings for uterine angioleiomyoma largely correspond to those of ordinary leiomyoma. 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. Abdominal pain was the most frequent presenting symptom. In one case, a cavernous ALM weighed 5.1 kg and contained 2 liters of blood (129). Angioleiomyomas (Vascular leiomyomas) that are thought to arise from vascular smooth muscle. In contrast to the very rare uterine ANS (see also ANS, Vol. Leiomyoma is the commonest benign neoplasm affecting uterus of females in the reproductive age group. Administering 10mg mifepristone vaginally daily achieved similar clinical results in a comparable sample (273). Conservative, organ-sparing surgery is also possible. 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). As a variant of LM, the “International Classification of Diseases for Oncology” deems such tumors benign and codes them with “0” (183). A clinicopathologic study of five distinctive hemorrhagic leiomyomas associated with oral contraceptive usage, A Comparative Morphologic and Immunohistochemical Analysis of 33 Highly Cellular Leiomyomas and Six Endometrial Stromal Nodules, Two Frequently Confused Tumors, Cotyledonoid dissecting leiomyoma of the uterus. Due to its good adverse effect profile, UPA might be particularly adequate for treating strong hypermenorrhea. Five histologically distinctive uterine smooth muscle neoplasms with multifocal hemorrhages termed apoplectic leiomyomas were studied. Malignant tumor of the myometrium was diagnosed in one hysterectomy specimen out of 1,845 specimens. In CECT, the presence of prominent, wound, vessellike enhancing structures in tissue masses that are well-delineated from the uterine wall should be regarded as being suggestive of ALM. Affected women are aged between 23 and 73 years (mean 44, median 46). R0 resection is the method of choice when there is extrauterine spread. Cleft-like spaces, some representing compressed vessels, others due to internodular edema, were present in 24 of the tumors and were conspicuous in 15 of them. Background: Uterine leiomyoma with lymphoid infiltration is an extremely rare variant of leiomyoma. Variants of leiomyoma (angio- and lipoleiomyoma, cotyledonoid and cellular leiomyoma, leiomyoma with bizarre nuclei, mitotically active, epithelioid and myxoid leiomyoma), smooth muscle tumors with uncertain malignant potential (atypical smooth muscle tumors), disseminated peritoneal leiomyomatosis, benign metastasizing leiomyoma, intravenous leiomyomatosis Such lesions are reviewed in this article with detailed descriptions of their morphology, differential diagnosis and correlation with biological behaviour. Very large tumors often exhibit necrosis. In contrast to the suspicious clinical and macroscopic findings, the risk of mistaking ALM with sarcoma in histology is low. Majority of the cases were multiparous females (88.6%) in fourth and fifth decades of life (77%) and presenting with heavy menstrual bleeding (35.9%). detection of these patients and the implementation of surveillance measures for renal cell carcinoma. A thorough examination and adherence to the standard diagnostic criteria is required to rule out malignancy. We report four cases of an unusual uterine smooth muscle neoplasm. The Uterine corpus Sternbergs diagnostic surgical pathology. The solid components show strong enhancement in contrast MRI. Hysterectomy is the procedure of choice, organ-sparing surgery is possible. ALM have a Ki67 index of between 0 und 25% (mean 2%) (156). 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). The cells have an oval nucleus and are long and slender, and usually there is very little atypia (although there are some benign variants of leiomyoma that have atypia). The very rare uterine ANS macroscopically differ from ALM in that they are poorly circumscribed, while microscopy reveals pronounced cellular pleomorphism and positive immunostaining for ERG and CD31. The same applies for primary or neoadjuvant CHT and/or RT in generally inoperable cases. During the follow-up time no tumour recurrence was detected and the quality of life of the patient improved significantly. 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. 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 (36, 84). Cotyledonoid LM is largely identical to ordinary LM in sonography (121) and MRI (152). Arteriovenous malformations have similar features and appearance to hemangiomas (84). A causal relationship between apoplectic leiomyomas and oral contraceptive usage is strongly suggested. 1,2. World Health Organization of Tumours. Women are noticeably more frequently affected than men are. To the best of our knowledge, only 20 cases have been reported till date in the literature. HE constitutes the therapeutic measure of choice. Most ALM arise in the skin of the extremities (89%) and in the vicinity of the head (9%) (82). The PET-CT shows no increase of activity (91). Twenty-eight of the leiomyomas were intramural and five, submucosal. Microscopic examination disclosed a diffuse growth of closely packed small cells with scanty cytoplasm and nuclei that lacked atypia. Immunostaining for CD10 and HMB45 is negative in ALM. FH-deficient uterine leiomyomas can show characteristic morphologic features (FH-d morphology) that have been previously described. The specimens were properly labeled, fixed (in NBF), examined grossly, processed, stained and examined microscopically. FH IHC can show variable results and presence of retained FH staining should not be used to exclude the possibility of HLRCC. The same applies for primary and neoadjuvant CHT and/or RT in generally inoperable cases. Majority of the women with endometrial carcinoma were multiparous (76.9%) and belonging to the age-group of 50–59 years (38.4%). 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 ]. Total hysterectomy is the measure of choice. Almost all women with HLRCC develop symptomatic uterine leiomyomas resulting in surgery at young ages, presenting an ideal opportunity for early, Join ResearchGate to discover and stay up-to-date with the latest research from leading experts in, Access scientific knowledge from anywhere. Symptoms most closely resemble those of LM. However, neither DLM nor a malignant tumor can be properly ruled out via diagnostic imaging (187). No data have been published on the treatment of ALM with progestins, antiprogestins, GnRH analogues and UPA. Six tumors had grade 3 nuclei. ... Betegünknél ösztrogén-és WT1-pozitivitás volt kimutatható. ALM are without doubt benign. 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. Such findings sometimes also constitute a cystic adenomyoma, or innate intrauterine cysts (204). related lesions. The presence of ample dilated vessels renders ALM relatively soft compared to ordinary uterine LM, and elastic like rubber. Angioleiomyomas do not require special aftercare or follow-up. Genital leiomyoma, from smooth muscle of the scrotum, nipples and labia majori [1]. Of the total leiomyoma variants, 60% (n = 34) were cellular leiomyoma, 19.6% (n = 11) were mitotically active leiomyomas (MAL),14.3% (n = 8) were leiomyomas with bizarre nuclei (LBN), and 5.4% (n = 3) cases were reported as smooth muscle tumour of uncertain malignant potential (STUMP). These voids are noticeably larger in cavernous ALM, and can achieve the size of small cysts. With the aid of human medical nomenclature, these masses were diagnosed as epithelioid leiomyoma and myxoid leiomyoma, respectively. Cotyledonoid dissecting leiomyoma is accompanied by symptoms comparable to those of ordinary leiomyoma. These tumours are benign, but some of the variants and secondary changes may create diagnostic difficulties. pathology (4th ed). CLINICOPATHOLOGICAL STUDY OF UTERINE LEIOMYOMAS IN HYSTERECTOMY SPECIMENS; A RETROSEPTIVE STUDY. Aims Atypia or not, they have a very low mitotic index. One patient had also received adjuvant radiation therapy. 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. These suspicious clinical findings can lead to (even intraoperative) confusion with a malignant mesenchymal tumor. However, there are some tumours which exhibit unusual morphological features or growth patterns that cause difficulty in their distinction from malignant neoplasms and those with endometrial stromal differentiation. 9 types of leiomyoma variants were seen, amongst which cellular leiomyoma (6.33%) was the commonest. Cytokeratins are not expressed. Majority of leiomyoma cases (99.2%) were usual leiomyoma. 6: Mitotically active leiomyoma; (a): The tumor is composed of uniform spindle cells with elongated nuclei and eosinophilic cytoplasm. 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. Taking all of the presented findings and features together should suffice to at least suspect ALM. On microscopic examination, they were densely cellular and composed of cells that ranged from round to spindle-shaped and had scanty cytoplasm. There are a number of leiomyoma variants in which the smooth muscle neoplasm manifests one histologic facet typical of malignant neoplasm, yet lacks others. Macroscopically speaking, angioleiomyomas are well-delineated tumors with a rubber-like consistency on palpation, and can appear solid and cystic. GnRH analogues or ulipristal acetate can be applied in order to bridge time until surgery and as a means for controlling symptoms. The aim of this study is to describe in detail the clinical and pathologic characteristics of uterine leiomyomas from women with HLRCC. Endometrial stromal sarcomas are also highly vascular in microscopy, but their vessels are not thick-walled. The strong degree of vascularity lends such tumors a brownish-red to deep red/blueish-red (Fig. Fig. Method: Hysterectomy and myomectomy specimens received over a period of two years were studied. Furthermore, ALM have clinical features that are suggestive of malignant behavior, but do not fulfill the malignancy criteria. 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. Material and Methods: Consecutive 119 specimens of leiomyoma, leiomyoma variants, STUMP and LMS from the pathology archives of Bezmialem Medical Faculty and Cerrahpasa Medical Faculty were selected. The vascular component is immunoreactive for CD34 (84), though there are also reports of CD34 negative tumors (58). The implications of a rapidly growing uterus are discussed at length in the chapter on LMS (, The results provided by a working group of the DKSM reveal that LLM account for 0.98% of LM (126). The most common feature in patients with multiple piloleiomyomas (cutaneous leiomyomas) is pain, which can be spontaneous or induced by cold or tactile (eg, pressure) stimuli. 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. Rapid growth is not uncommon. LLM can also arise in the vicinity of the ligamentum latum (260). The solid tissue was frequently yellow. Histological variants of leiomyosarcoma. of the Breast and Female Gynetical Organs. 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. 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. Infarction-type necrosis was seen in 3 cases, and a coagulation-type necrosis was seen in 2 cases of … At laparotomy, an exophytic congested bulky tumor resembling placental tissue extended from the uterine wall into the broad ligament and pelvic cavity. A diagnosis of an adipocytic tumor can be secured via fat suppression (13, 149). 1.9.1). Leiomyomas are composed of bundles of smooth muscle cells that look very much like those of the normal myometrium. Malignant tumor of … Günter Köhler, Katja Evert, Marek Zygmunt and Matthias Evert. Specimens showed conventional leiomyomas, cellular leiomyomas and leiomyomas with bizarre nuclei. The borders between these two components can be irregular, i.e. Fig. related lesions. Histopathology 2007; 50:851–858 [Google Scholar] Recognition of their distinctive pathologic features will prevent misdiagnosis as leiomyosarcoma. Uterine leiomyomas are common benign tumors of the myometrium. 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 commonest clinical presentation of patients in the present study was menorrhagia (79.1%) which may be due to increased vascularity of endometrial surface and altered uterine contractility; followed by abdominal pain (10%) possibly due to degenerative changes in leiomyomas our results similar to studies by Gowri et al, 10 Begum et al, 13 Chathana et al 14 and Selvambigai et al.
