Soft tissue tumors, both benign and malignant, of the testes are relatively uncommon. Primary leiomyosarcoma of the testis is rare, and its clinical behavior is difficult to predict. We report a case of paratesticular leiomyosarcoma in a 71-year-old man. Routine histologic examination and immunohistochemical staining were performed. The tumor was composed of interlacing fascicles of smooth muscle cells with marked nuclear pleomorphism and three to four mitoses per high power field, with few atypical mitoses. On the basis of the microscopic examination and immunohistochemical studies, the tumor was identified as a paratesticular leiomyosarcoma. The published studies on this entity are reviewed.
睾丸的良性和恶性软组织肿瘤相对少见。睾丸原发性平滑肌肉瘤罕见，其临床行为难以预测。我们报告一例71岁男性的睾丸旁平滑肌肉瘤病例。进行了常规组织学检查和免疫组化染色。肿瘤由平滑肌细胞的交错束组成，具有明显的核多形性，每高倍视野有三到四个有丝分裂象，非典型有丝分裂象少见。根据显微镜检查和免疫组化研究，该肿瘤被确诊为睾丸旁平滑肌肉瘤。本文对已发表的关于该实体的研究进行了综述。
