Fibrous histiocytoma is a benign tumor of mesenchymal origin. The tumor frequently appears in sun exposed areas on skin and orbital tissues. The subcutaneous appearance of this tumor in deep soft tissues is rare. We present here the eighth reported case of subcutaneous benign fibrohistiocytoma in a 27 year old male patient. Histopathology of the tumor comprises fibroblastic and histiocytic cells which mimic dermatofibroma, xanthomas and nodular fasciitis. Special stains like vimentin can only differentiate these tumors.
纤维组织细胞瘤是一种间叶源性良性肿瘤。该肿瘤常出现在皮肤和眼眶组织的暴露于阳光下的区域。这种肿瘤在深部软组织中的皮下表现较为罕见。我们在此报告一例27岁男性患者的皮下良性纤维组织细胞瘤,这是第八例报道病例。肿瘤的组织病理学表现为成纤维细胞和组织细胞,类似于皮肤纤维瘤、黄瘤和结节性筋膜炎。像波形蛋白这样的特殊染色只能区分这些肿瘤。
