Melanoacanthoma is an extremely rare pigmented benign mixed epithelial tumor of both
melanocytes and keratinocytes. A 52-year-old female presented an asymptomatic, slightly elevated, 1. 2 cm x 0. 8 cm, dark black-colored plaque on her right buttock of 2 years' duration. Histopathologic finding of the plaque shows hyperkeratosis, focal parakeratosis, follicular plugging, acanthosih, papillomatosis and pseudo-horn cyst in the epidermis. The tumor is composed of basaloid and squarnous cells with many foci of clusters and whorls of melanin pigment-laden cells. Electron microscopic finding reveals many scattered melanocytes in the entire epidermis. Melanin granules are found mostly
in the melanocytes but can also be found in a few keratinocytes.
