Oral Melanoacanthoma: A Case Report, a Review of the Literature, and a New Treatment Option

By Brian T. Andrews Md


Objectives: Oral melanoacanthoma is a rare condition that presents as a pigmented, painful lesion, most commonly on the buccal mucosa. Argon plasma coagulation is a new treatment option for benign oral lesions and is hypothesized to be efficacious for this rare mucosal disorder. Methods: Treatment of a case and a review of the English-language literature were performed. Results: One patient received a diagnosis of oral melanoacanthoma, and argon plasma coagulation treatment resulted in ablation of the lesion with excellent mucosal healing. A review of the literature demonstrated that this lesion is most commonly associated with black (90.9%), adult female (69,7%) patients and is most commonly located on the buccal mucosa (64.7%). Conclusions: Oral melanoacanthoma is a rare, benign mucosal lesion that may require surgical intervention for symp-tomatic relief. Argon plasma coagulation is a relatively safe and effective means of treating this lesion. Argon plasma coagulation treatment may be expanded to include other benign, superficial lesions of the oral mucosa. Key Words: argon plasma coagulation, melanoacanthoma, oral melanoacanthoma
