INTRODUCTION
Discoid lupus erythematosus can affect periungual tissues leading to onychodystrophy. Squamous cell carcinoma can occur in persistent scars of discoid lupus; this rare occurrence has not yet been reported on the nail unit. Case presentation: we report a case of squamous cell carcinoma occurring on the distal phalanx of the thumb in a patient with longstanding periungual discoid lupus on several fingernails.
DISCUSSION
Periungual discoid lupus erythematosus is rare. The scars caused by this disease can very rarely develop into squamous cell carcinoma. This is the first report of this occurrence at the periungual tissues.
引言
盘状红斑狼疮可累及甲周组织，导致甲营养不良。鳞状细胞癌可发生于盘状红斑狼疮的持久性瘢痕中；这种罕见情况在甲单位尚未见报道。病例报告：我们报告1例鳞状细胞癌发生于1例多个指甲患有长期甲周盘状红斑狼疮患者的拇指远端指骨。
讨论
甲周盘状红斑狼疮罕见。这种疾病引起的瘢痕极少发展为鳞状细胞癌。这是甲周组织发生这种情况的首例报告。
