Abstract Background Lipoleiomyoma is a rare, benign variant of the commonplace uterine leiomyoma. Unlike leiomyoma, these tumors are composed of smooth muscle cells admixed with mature adipose tissue. While rare, they are most frequently identified in the uterus, but even more infrequently have been described in extrauterine locations. Case presentation We describe a case report of a 45-year-old woman with a history of in vitro fertilization pregnancy presenting 6 years later with abdominal distention and weight loss found to have a 30-cm intra-abdominal lipoleiomyoma. While cross-sectional imaging can narrow the differential diagnosis, histopathological analysis with stains positive for smooth muscle actin, desmin, and estrogen receptor, but negative for HMB-45 confirms the diagnosis of lipoleiomyoma. The large encapsulated tumor was resected en bloc. The patients post-operative course was uneventful and her symptoms resolved. Conclusions Lipoleiomyoma should be considered on the differential diagnosis in a woman with a large intra-abdominal mass. While considered benign, resection should be considered if the mass is symptomatic, and the diagnosis is unclear or there is a concern for malignancy.

Vulvar Mass

Smooth muscle tumors arising in the vulva are rare. Leiomyosarcoma is the most common variant of vulvar sarcoma, and very few cases have been reported during pregnancy. A 36-year-old woman presented with a progressively enlarging vulvar mass during pregnancy, diagnosed as a Bartholin's gland cyst. The lesion was resected at 38 weeks of gestation during cesarean section and diagnosis of myxoid leiomyosarcoma of the vulva was made. Six weeks later the patients were referred to our center and submitted to wide vulvar excision with groin lymph node dissection that revealed the presence of a small residual focus of leiomyosarcoma. At 30 months of follow-up the patient was well without any sign of recurrent disease. Leiomyosarcoma should be included in the differential diagnosis of vulvar masses; progressively enlarging vulvar lesion should be biopsied even during pregnancy. Leiomyosarcoma should be considered in the differential diagnosis of vulvar mass.

Herein we report a rare case of a giant myopericytoma presenting in a 16-year-old girl as a slowly progressive swelling involving the scalp in the occipital region. It was managed by complete excision. Histological examination of the lesion revealed  spindle-shaped cells forming characteristic rosettes around the blood vessels, and positive staining with smooth muscle actin.

AbstractLeiomyosarcoma is a malignant tumour of smooth muscle origin. These tumours are rarely encountered in the head and neck region. A case of leiomyosarcoma of the auricle is presented. There are two cases of external auditory canal leiomyosarcoma in the literature. To our knowledge the present case is the first example of leiomyosarcoma of the auricle.

Abstract 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 müllerian 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 müllerian 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 müllerian system in response to estrogenic stimulation.

Abstract Pancreatic lymphangiomas, which occur predominantly in women, are rare and account for only 1% of all lymphangiomas. The characteristic histologic features include multiple cysts lined by endothelial cells, irregularly distributed smooth muscle cells, and lymphoid aggregates in the wall of the cyst. We describe a 36-year-old woman with lymphangioma of the pancreas with “ovarian-like” mesenchymal stroma in the wall. This stroma, composed of uncommitted mesenchymal cells, has not been described previously in the wall of pancreatic lymphangiomas. Multiple small lymphatic channels that are found in this stroma recapitulate the development of lymphatic channels in the embryo. Lymphangioma of the pancreas may arise from distension of these lymphatic channels. Pancreatic lymphangioma may, therefore, be a developmental anomaly rather than a true neoplasm.
