While inherently painless, it grows progressively and leads to nail deformity which eventually produces pain and has negative impact on the quality of life of the affected individual. The present paper presents a step-by-step guide to the in situ split-thickness toenail bed graft technique. The outcome of our case was in line with the current literature, the preservation of the nail led to a highly satisfactory cosmetic result, while no recurrence of the lesion was reported.
