Abstract

Liposarcoma is a rare primitive mesenchymal tumor, developed at the expense of adipose tissue and with a preferential location in the thigh. We report an observation of liposarcoma in the buttock. A 56-year-old man, presented with a tumor of the right buttock for 2 years. Examination revealed an inflammatory, ulcerated tumor in the upper-external quadrant of the right buttock, measuring about 8 cm. Bilateral inguinal adenopathies were associated. The diagnostic hypotheses were: a squamous cell carcinoma, a cutaneous lymphoma, and cutaneous metastases. An anatomical examination confirmed the diagnosis of myxoid round-cell liposarcoma. The extension work-up appeared compatible with secondary pleuropulmonary, hepatic, cutaneous, and lymph node neoplastic localizations. The patient was treated with chemotherapy with the Adriamycin-carboplatin protocol. The evolution was rapidly fatal after a few weeks after the first course of chemotherapy. It should be evoked in front of any ulcerated tumor of the buttock.

摘要

脂肪肉瘤是一种罕见的原始间叶性肿瘤，由脂肪组织发展而来，优先发生于大腿。我们报告一例臀部脂肪肉瘤。患者男，56 岁，2 年前发现右臀部肿瘤。检查发现右臀部上外象限有一炎性溃疡肿瘤，大小约 8 厘米。双侧腹股沟淋巴结肿大。诊断假设为：鳞状细胞癌、皮肤淋巴瘤和皮肤转移。解剖检查证实为黏液样圆形细胞脂肪肉瘤。扩展工作符合继发性胸膜肺、肝、皮肤和淋巴结肿瘤定位。患者接受阿霉素-卡铂方案化疗。在第一疗程化疗后数周内，病情迅速恶化，导致死亡。在任何臀部溃疡性肿瘤的情况下，都应该考虑到这种疾病。
