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. Leiomyomas. To study the histopathology of uterine tumors, classify them as per WHO 2014 classification and correlate with clinical parameters. Angioleiomyomas exhibit a huge degree of vascularization. LLM have an average diameter of 4.6 cm. Atypical leiomyoma: This lesion likely falls on a spectrum between leiomyoma and leiomyosarcoma. Very large tumors often exhibit necrosis. World Health The latter has nothing to do with angiomyolipoma from the PEComa family (cf. The large volumes of blood involved can complicate tumor enucleation or morcellation procedures. Abstract. 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). No data have been published on the treatment of ALM with progestins, antiprogestins, GnRH analogues and UPA. (5th ed), vol.2, New York: Churchill Livingstone 2003. However, angioleiomyomas are noticeably softer and often exhibit rapid growth. All available slides were reviewed and FH IHC staining was performed on multiple blocks when possible. The distinctive gross appearance and microscopic features are embodied in the designation, “cotyledonoid dissecting leiomyoma.” The follow-up information available for three cases supports the benign nature of the tumor. Affected women frequently have disorders in their fat-related metabolism and are often heavy by comparison. Clinicopathologic characteristics were analyzed and … The solid structures thus correspond to the MRI picture of LM. They give the tumor a placenta-like appearance. The symptoms of and findings for uterine angioleiomyoma largely correspond to those of ordinary leiomyoma. understand their molecular biology, in this review, we assemble literature data from 2005 to 2019 that focuses on findings related to ULM and ULMS genetics and epigenetics. Conservative, organ-sparing surgery is also possible. The Uterine corpus Sternbergs diagnostic surgical pathology. Aims There is no indication for systemic or radiogenic therapy. Majority of the women with endometrial carcinoma were multiparous (76.9%) and belonging to the age-group of 50–59 years (38.4%). ALM are without doubt benign. Multiple cutaneous (or pilar) leiomyomas arising from the arrectores pilorum muscles. These two structures irregularly blend into each other. that the uterus was disease-free (152). All rights reserved. As myoma variants are rare, it is undoubted that myoma variants of the cervix are extremely rare. Cellular leiomyoma (1.8%) was the most common histologic variant; the secondary change was hyalinization (27.8%). However, there are also reports of cases in which there was no recurrence despite R1 resection and the presence of LVI (81, 224). 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. The pain or tenderness also may be secondary to pressure on nerve fibers within the tumor; however, some authors believe it may be solely due to contraction of muscle fibers. Thus, in both the clinical and pathological settings, it can be difficult to distinguish from leiomyosarcoma. The follow-up information available for three cases supports the benign nature of the tumor. There is no indication for adjuvant or additive RT, CHT or HT. Pathology and Genetics of Tumours R0 resection is the method of choice when there is extrauterine spread. Compared to malignant ovarian tumors, however, ascites is absent and CA-125 values are not elevated in ALM (22, 84, 102). Microscopic examination disclosed a diffuse growth of closely packed small cells with scanty cytoplasm and nuclei that lacked atypia. 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. The characteristic microscopic feature serving as the basis for inclusion in this study is the rounded to polygonal shape of the majority of cells instead of the elongated blunt-ended shape of smooth muscle cells seen in the typical leiomyoma. They appear to predominantly arise in postmenopausal women (259). No recurrences developed up to 12 years after operation. or leiomyoma variants 2.3. However, hemangiomas and ALM differ in that the former is usually not well-delineated from its surroundings, neither macroscopically nor microscopically. 6: Mitotically active leiomyoma; (a): The tumor is composed of uniform spindle cells with elongated nuclei and eosinophilic cytoplasm. 1.2.1: Histologic aspect of a lipoleiomyoma. 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). Angioleiomyomas (Vascular leiomyomas) that are thought to arise from vascular smooth muscle. 15 Secondary degenerative changes often occur in leiomyoma which may alter the gross appearance and even microscopical features. Arteriovenous malformations have similar features and appearance to hemangiomas (84). Rapid growth is not uncommon. The most location was intramural (68.9%). 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). Severe pelvic pain can arise when there is spread within the pelvis. All patients were found to have been taking a combination-type oral contraceptive hormonal medication containing the progestin norethindrone for 2-4 years. Eleven of 18 whose consistency is known were soft, fish-flesh, or rubbery, 10 were yellow or yellow-tan; one had a prominent cystic component. In: Hendrickson MR, Five histologically distinctive uterine smooth muscle neoplasms with multifocal hemorrhages termed apoplectic leiomyomas were studied. women. These tumours are benign, but some of the variants and secondary changes may create diagnostic difficulties. 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. Conclusion: Leiomyoma was the most common pathology found in hysterectomy specimens in … Intratumoral bleeding with clotting occasionally results in consumptive coagulopathy (88). 2, Chapter 4). Günter Köhler, Katja Evert, Marek Zygmunt and Matthias Evert. THE is the standard surgical procedure. Purely adipocytic areas appear yellow and are very soft. The uniform spindle-like smooth muscle cells are often swirled around the vessels (36). 1.9.1). To read the full-text of this research, you can request a copy directly from the authors. The presence of ample dilated vessels renders ALM relatively soft compared to ordinary uterine LM, and elastic like rubber. Similar findings were noted in many other studies. Angioleiomyomas have marked strong central vascularity in Doppler sonography. Adhesions with neighboring organs without infiltration are not uncommon (224). these neoplasms is difficult by the symptoms overlapping, sharing of morphological and molecular characteristics, being possible to classify them only after the surgical procedure. Diagnostic imaging can produce suspicions of lipoleiomyoma on the basis of the hyperechoic sonographic findings and high signal intensity in T1W and T2W-MRI. Sarcoma would be a justifiable differential diagnostic consideration in these cases. Most common location of leiomyoma’s was intramural (57.43%) followed by subserosal (30.69%). The Uterine corpus. Only morphologic variants of leiomyoma (cellular leiomyoma, leiomyoma with bizarre nuclei, etc. AI apparently inhibits aromatases and, subsequently, the production of estradiol within LM (63). A diagnosis of an adipocytic tumor can be secured via fat suppression (13, 149). All the neoplasms had a prominent component of arterioles, which in one tumor had hyalinized walls. All had highest mitosis counts of 0 to 3 MF/10 HPF, except one (5 MF/10 HPF). 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. In one case, a cavernous ALM weighed 5.1 kg and contained 2 liters of blood (129). Pedunculated subserosal ALM can reach considerable dimensions and are barely discernible from mobile ovarian tumors on palpation (84). 2, Chapter 1), ALM do not express CD34 (58). Objectives: To know the incidence of leiomyoma in hysterectomy specimens and study the degenerative changes of leiomyoma and its variants. As a variant of LM, the “International Classification of Diseases for Oncology” deems such tumors benign and codes them with “0” (183). of the Breast and Female Gynetical Organs. 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. However, the clinical features of ALM justify that they are discussed in the context of LM. Otherwise, pains are rather the exception in patients with genital ALM, and more frequently occur when the tumor is localized in the extremities. Mixtures of epithelioid, clear-cell, and plexiform patterns occurred with sufficient frequency to indicate that such patterns are variants of a single entity. Majority of the patients were between 41-50 years (46.84% cases). 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). Some researchers believe that a degenerated ULM can turn into a ULMS; others claim that ULMSs can only arise de novo. In our case the lymphoid infiltration was reactive which was confirmed on immunohistochemistryInternational Journal of Human and Health Sciences Vol. These voids are noticeably larger in cavernous ALM, and can achieve the size of small cysts. WG, Haller U, Kubik-Huch RA. Thirty-three highly cellular leiomyomas of the uterus from patients 29 to 65 (mean, 46) years of age and six endometrial stromal nodules from patients 41 to 53 (mean, 46) years of age are described. Temporary treatment with GnRH analogues can, therefore, be adequate for bridging the time until surgery or impending menopause. Mesenchymal tumours and Fat tissue can account for strongly varying shares of total tumor volume (. Under WHO Classification, LLM is regarded as an independent variant of LM (183). The histological variants which posed diagnostic difficulties were cellular leiomyomas, atypical leiomyoma, epithelioid leiomyoma, and leiomyomas with secondary changes including haemorrhagic infarction, myxoid change and perinodular hydropic change.
