Abstract

Extrathoracic solitary fibrous tumours have been reported in almost all anatomic sites, but reports of tumours in the extremities or in intramuscular locations, as well as of tumours with atypical histological features and malignant behaviour, are rare. Herein the authors describe a case of hemangiopericytoma-solitary fibrous tumour that arose in the gluteal region of a 47-year-old woman. The tumour showed atypical histological features, such as high cellularity, increased mitotic activity and focal expression of cytokeratins.

摘要

胸外孤立性纤维瘤几乎在所有解剖部位均有报道，但关于四肢或肌肉内肿瘤以及具有非典型组织学特征和恶性行为肿瘤的报道却很罕见。在此，作者描述了一例发生在一名47岁女性臀区的血管外皮细胞瘤-孤立性纤维瘤病例。该肿瘤表现出非典型组织学特征，如细胞密度高、有丝分裂活性增加以及细胞角蛋白的局灶性表达。
