Abstract

Spindle cell lipoma usually occurs as a solitary, subcutaneous, circumscribed lesion in the back, posterior neck or shoulders of older men. As a paratesticular tumor, spindle cell lipoma is extremely rare. Herein we report the second case of spindle cell lipoma of the spermatic cord in the published reports. The tumor comprised mature adipocytes and uniform spindle cells within thick ropey collagen bundles and mast cells. Immunohistochemical studies showed spindle cells positive for CD34, a diagnostic feature of this tumor.

摘要

梭形细胞脂肪瘤通常表现为孤立的、位于皮下的、边界清晰的病变，多见于老年男性的背部、后颈部或肩部。作为一种睾丸旁肿瘤，梭形细胞脂肪瘤极为罕见。在此我们报告已发表文献中第二例精索梭形细胞脂肪瘤。肿瘤由成熟脂肪细胞、厚条索状胶原束内均匀的梭形细胞以及肥大细胞组成。免疫组织化学研究显示梭形细胞CD34呈阳性，这是该肿瘤的一个诊断特征。
