Abstract
-
Epidermal nevus arises from the pluripotential germinative cells in the basal layer of the embryonic epidermis. Histologically, it has a distinctive feature of hyperkeratosis, papillomatosis and acanthosis with elongation of the rete ridges. Epidermal nevus also has other histological variations. We report a case of a 5-year-old male who presented with pruritic linear brownish scaly papules on the right thigh. The lesion showed histological features of combined epidermolytic hyperkeratosis and porokeratosis type of epidermal nevus.
