증례 : Tacrolimus 국소도포로 치료한 빨래판 손톱

Abstract

Washboard nail is a dystrophy that presents as a series of ridges that extends across the nail. It is often accompanied by a central depression that extends from the cuticle to the free edge. Washboard nail is often a result of frequently repeated trauma, but sometimes predisposing factors cannot be found. When habitual tic is the cause of the lesions, restraining the habit is the most important treatment. Here, we report a case of a 6-year-old male with washboard nails on both thumbnails and was treated with topical 0.1% tacrolimus ointment. Significant improvement was observed after 4 months of application. This case suggests that topical tacrolimus can be considered as a primary therapy in the treatment of washboard nails in the absence of trauma.
