Subungual angiokeratoma is extremely rare. Only 1 case is reported in the literature, presenting as a longitudinal pigmented band on a toenail. We report a case of a subungual angiokeratoma on a fingernail of a 43-year-old woman, clinically mimicking a squamous cell carcinoma. Medical imaging revealed a soft tissue tumor and erosion of the distal phalanx. Although extremely rare, solitary angiokeratomas may arise in the nail apparatus and should be added to the differential diagnosis of subungual warty tumors.
甲下血管角皮瘤极为罕见。文献中仅报道过1例，表现为趾甲上的纵向色素沉着带。我们报告1例43岁女性手指甲上的甲下血管角皮瘤病例，临床上酷似鳞状细胞癌。医学影像显示为软组织肿瘤及远节指骨侵蚀。尽管极为罕见，但孤立性血管角皮瘤可发生于甲器，应列入甲下疣状肿瘤的鉴别诊断。
