We report a subungual extraskeletal chondroma with a convex nail deformity originating from the index finger in a 39-year-old man. The tumor was excised and its histopathology showed obvious nuclear pleomorphism. However, the Ki-67 (MIB-1) labeling index was less than 1%, indicating low proliferative activity; it was classified as an extraskeletal chondroma with atypical features. There was no recurrence over a 3-year postoperative period.
我们报告了一例发生于一名39岁男性示指的伴有指甲凸起畸形的甲下骨外软骨瘤。肿瘤被切除，其组织病理学显示明显的核多形性。然而，Ki-67（MIB-1）标记指数小于1%，表明增殖活性低；它被归类为具有非典型特征的骨外软骨瘤。术后3年无复发。
