A rare case of oral melanoacanthoma

Aanchal Tandon et al. J Oral Maxillofac Pathol. 2018 Sep-Dec.

Abstract

Oral melanoacanthoma is a rare, pigmented lesion which brings suspicion of a malignancy with its sudden appearance and rapid growth. It is characterized clinically as a brown-black lesion and histologically it shows acanthosis of the superficial epithelium and proliferation of dendritic melanocytes. Due to their unusual clinical pattern, biopsy is mandatory to rule out malignancy.

Keywords: Melanoacanthoma; melanoma; oral pigmentation.
