1/2. leiomyoma of the round ligament in a postmenopausal woman.OBJECTIVE: leiomyoma of the round ligament of the uterus is a rare condition. We present the first case of a postmenopausal, previously hysterectomised, woman who received combined hormonal replacement therapy and developed a leiomyoma of the right round ligament. METHOD: In sections of the tumor, immunohistochemical reaction with monoclonal antibodies against smooth muscle actin, desmin, vimentin, estrogen receptor and progesterone receptor was performed. RESULTS: The leiomyoma showed bizarre histologic appearance in absence of mitotic figures and degenerative changes. Leiomyocytes presented a positive immunohistochemical reaction with monoclonal antibodies against smooth muscle actin, desmin vimentin and progesterone receptor in absence of estrogen receptor. CONCLUSION: Progestin as part of a combined hormonal replacement therapy may play an important role in promoting the development of leiomyoma in hormonal responsive tissue of the round ligament in postmenopausal women.- - - - - - - - - - ranking = 1keywords = ligament (Clic here for more details about this article) |
2/2. Uterine-like mass with features of an extrauterine adenomyoma presenting 22 years after total abdominal hysterectomy-bilateral salpingo-oophorectomy: a case report and review of the literature.adenomyoma is a benign tumor composed of smooth muscle and benign endometrium. These tumors typically originate within the uterus. An extrauterine adenomyoma is a rare entity. We report a uterine-like mass consistent with an extrauterine adenomyoma presenting 22 years following a total abdominal hysterectomy and bilateral salpingo-oophorectomy. The mass was pear-shaped with uterine-type smooth muscle and a cavity lined by functional endometrial glands and stroma. To our knowledge, only 4 other cases of an extrauterine uterine-like mass are reported in the literature. Three involved the ovary, while one was located adjacent to the broad ligament with normal pelvic organs. Although none of these other uterus-like masses were described as adenomyomas with uterine-like features, the histologic findings are strikingly similar. An understanding of the mullerian system suggests that either an embryologic malformation or a differential multipotentiality existing in the subcoelomic tissues in response to hormonal stimulation results in a supernumerary mullerian structure like a uterus, as observed in this case. The presence of endometrial glands and stroma in the mass confirms that the tissues in this mass are hormonally responsive. It is most likely that this uterine-like mass arose from the tissues of the secondary mullerian system in response to estrogenic stimulation.- - - - - - - - - - ranking = 0.14285714285714keywords = ligament (Clic here for more details about this article) |
