Primary leiomyosarcoma of the breast treated by partial resection of the breast including nipple and areola: report of a case

Breast Leiomyosarcoma: A Systematic Review and Recommendations for Management

Background

Leiomyosarcomas of breast are very rare tumors, with only 54 cases reported in the literature to date.

Methods

We report a case of leiomyosarcoma in a 52-year-old woman who presented with a painless left breast mass in the upper outer quadrant of her left breast. It measured about 6 cm in diameter and was located within the breast parenchyma with no skin involvement. Mammogram was suggestive of BI-RADS IV lesion, and core biopsy of the lesion was inconclusive.

Results

Histopathology and immunohistochemistry of the excision biopsy of the mass confirmed the diagnosis of leiomyosarcoma approaching the specimen margins. The patient underwent simple mastectomy, which did not reveal any residual tumor or additional lesions. Follow-up for a year after her mastectomy did not show any local or systemic recurrence.

Conclusions

We reviewed the literature and summarize our findings as recommendations for management of leiomyosarcoma of breast.

Primary breast leiomyosarcoma and synchronous homolateral lung cancer: a case report

Radiological and histological features of breast leiomyosarcoma can mimic a wide variety of other breast lesions, such as mesenchymal tumors, breast lymphomas, poorly differentiated carcinomas and metaplastic breast carcinomas. The authors present the case of a 62-year-old woman with a primary breast leiomyosarcoma with synchronous ipsilateral lung adenocarcinoma. The latter was an incidental finding during pre-surgical staging examinations. Clinicopathological, immunophenotypic and imaging features cancer are described. A brief review of the literature on imaging findings and management of breast leiomyosarcoma is presented. The authors discuss the differential diagnoses in breast imaging and of the extra-mammary incidental findings. Surgical resection remains the cornerstone of treatment, while radiation therapy and chemotherapy remain to be defined on a single-patient basis.

Primary superficial femoral vein leiomyosarcoma: report of a case

The majority of leiomyosarcomas occur in the muscular layers of the gastrointestinal tract and uterus. Primary leiomyosarcomas rarely arise in the veins of the lower extremities. Primary leiomyosarcoma of the superficial femoral vein is extremely uncommon. We herein present a case of a 69-year-old man with a primary leiomyosarcoma of the superficial femoral vein of his left thigh, which manifested as an anteromedial palpable painless mass in the middle third of his left thigh. Duplex ultrasonography revealed a 4 × 8-cm mass attached to the left superficial femoral vein. The mass was removed surgically en bloc. Histological examination showed a low-grade leiomyosarcoma. Seven months after the resection, a local recurrence of the tumor was observed, and the patient underwent another surgery. Five years after the second operation the patient remains free of illness.
