A 49-year-old woman with a long history of a subcutaneous mass on the dorsal side of her 4 finger of the right hand visited a dermatologist because of slight enlargement of the mass. Her past medical history was notable only for a mitral valvuloplasty performed 20 years earlier. Physical examination revealed a small, round, firm subcutaneous mass on the dorsal side of her proximal interphalangeal joint of the right 4 finger. The mass was immobile and nontender and its overlying skin was intact. An excisional biopsy was done for the patient and the specimen was sent for pathologic evaluation. On microscopic examination, the final diagnosis of plexiform schwannoma was made for the lesion. The aim of this publication is to report a rare case of plexiform schwannoma of the soft tissue and a literature review to provide a better understanding about its characteristics including epidemiologic factors and pathologic evaluation.
一名49岁女性，右手无名指背侧有一皮下肿物病史较长，因肿物略有增大就诊于皮肤科医生。她的既往病史仅以20年前进行的二尖瓣成形术为显著。体格检查发现右手无名指近端指间关节背侧有一个小的、圆形、坚实的皮下肿物。肿物固定、无压痛，其上皮肤完整。为患者进行了切除活检，并将标本送去做病理评估。显微镜检查时，该病变最终诊断为丛状神经鞘瘤。本出版物的目的是报告一例罕见的软组织丛状神经鞘瘤病例，并进行文献综述，以更好地了解其特征，包括流行病学因素和病理评估。
