A 38-year-old woman presented with a keratotic lesion on the left thumb for 1 year. Six months before the lesion was noted, she had sustained a cut on the medial-third of the distal nail of left thumb extending to the base of the distal phalanx. Examination revealed a 1 cm × 0.5 cm, keratotic, nail-like lesion [Figure - 1]a. There was a longitudinal split on the medial third of the left thumb and the scar of the previous cut injury on the distal phalanx. The lesion was excised under distal digital block [Figure - 1]b. Histopathological examination revealed nail plate and nail matrix confirming the diagnosis of ectopic nail.
