Melanoacanthoma of Pinna-Treated with Skin Grafting: A Case Report

Abstract

Melanoacanthoma is a very rare cutaneous lesion and it is considered to be a benign neoplasm, which is composed of large dendritic melanocytes and epidermal keratinocytes. Very few case reports of melanoacanthoma have been described in Indian literature in recent past. We hereby report a case of melanoacanthoma in a 50-year-old male, who presented to us with a growth in right ear, since 30 years. On examination of right pinna, a 4×3 cm blackish irregular mass occupying the conchal region, encroaching towards the external auditory canal. Surgical excision of the growth was done, since the patient had cosmetic problem and for biopsy (to differentiate it from melanoma and to confirm the diagnosis). As the lesion was big so, to close the primary defect, split skin grafting was used as one of the treatment.
