The development of a basal cell epithelioma in a linear epidermal nevus is rare. We recently observed such a case in our clinic.
Report of a Case
A 42-year-old man was referred to us for treatment of bleeding growths in a congenital nevus. During the past decade, multiple, slowly enlarging nodules had developed, which bled when irritated. He was otherwise in excellent health.Physical examination showed a zosteriform, verrucous nevus traversing the right flank to the umbilicus and pubis and extending down along the medial aspect of the right leg. Discrete nodules up to 2 × 2 cm were present and ranged in color from pink to black. Several nodules were pedunculated (Fig 1).Biopsy of the nevus and of several nodules were performed.
The primary congenital lesion had features typical of an epidermal nevus.One of the nodules contained a tumor arising at several sites from the
