Cutaneous Melanoacanthoma

Cutaneous melanoacanthoma is a benign epithelial lesion that typically presents as a solitary black plaque or nodule, usually on either the head, neck, or trunk of an older adult in their seventh decade. The clinical features of a cutaneous melanoacanthoma mimic those of melanoma. As a result, diagnosis can be challenging as clinical, dermoscopic, and microscopic evaluations may necessitate biopsy for confirmation. Treatment involves conservative excision, with close monitoring for recurrence. While melanoacanthoma can occur in the oral mucosa as a reactive lesion, the presentation differs from cutaneous melanoacanthoma. Syndromes like Laugier-Hunziker syndrome may present with metachronous oral melanoacanthomas. This activity reviews the diagnosis, evaluation, and treatment of cutaneous melanoacanthoma and highlights the role of the interprofessional team in evaluating and treating patients with this condition. Given the diagnostic nuances of this benign lesion, interprofessional collaboration among primary care clinicians and dermatologists may enhance the quality of care, leading to reduced morbidity and mortality.
