Gingival melanoacanthoma: Case report and discussion of its clinical relevance
Tapia, Jose Luis / Quezada, Daniel / Gaitan, Luis / Hernandez, Juan C. / Paez, Carlos / Aguirre, Alfredo
Oral melanoacanthoma is an uncommon reactive condition that appears as a solitary pigmented lesion and is most often found on the buccal mucosa. For it to appear in the gingiva is extremely rare-only 11 cases are reported in the literature. This article presents a case of gingival melanoacanthoma and reviews the previously published cases. Because gingival melanoacanthoma shares clinical features with other pigmented lesions with diverse genesis, the differential diagnosis of a solitary pigmented lesion on the gingiva is also discussed.
