We report a case of two neuromuscular choristomas occurring in separate cutaneous locations in a healthy 3-month-old infant. Both lesions had an identical histologic appearance and were composed of mature skeletal muscle cells admixed with nerve fibers. In all previous reports, neuromuscular choristoma has arisen in association with a major nerve, and most lesions have been solitary. The two separate cutaneous choristomas in this case suggest that this lesion may arise from the neuroectodermal-derived Schwann cell.
我们报告了一例健康3个月大婴儿在不同皮肤部位出现的两例神经肌肉迷离瘤。两个病变具有相同的组织学外观，均由成熟的骨骼肌细胞与神经纤维混合组成。在以往所有报告中，神经肌肉迷离瘤均与主要神经相关出现，且大多数病变为单发。该病例中两个独立的皮肤迷离瘤提示此病变可能起源于神经外胚层来源的施万细胞。
