title: Acquired fibrokeratoma presenting as a giant pedunculated lesion on the heel.
abstract: Acquired digital fibrokeratomas (ADF) are benign and uncommon lesions consisting of collagenous papules and nodules covered by hyperkeratotic epidermis. These tumors occur mainly on the fingers and toes and infrequently on the palms and soles. They may possibly be triggered by a reaction to a trauma, ADF usually present as small and solitary dome-shaped lesions with a collarete of slightly raised skin at the base. We report a rare case of fibrokeratoma of the heel, presenting as a large and pedunculated nodule.
