The melanoma is a malignant neoplasm of melanocytic origin, and four clinicopathologic types are recognized: lentigo maligna melanoma, superficial spreading melanoma, nodular melanoma and acral lentiginous melanoma (ALM). The latter differs from ordinary malignant melanoma in exhibiting a predominant radial growth phase. ALM of the oral mucosa is rare. Although the prognosis of such lesions is reportedly poor, some studies show encouraging results with early diagnosis and adequate treatment. The present case highlights the potential role of a dental surgeon in early detection and recognition of signs of malignancy in melanotic lesions. A loose denture may be the only complaint of such a lesion. The need for biopsy at multiple sites to ensure accurate diagnosis is also highlighted. The management of oral ALM is discussed.
