 | Media file 1: Man with an ulcerated, blue-black, slightly elevated lesion in the edentulous, posterior maxilla on the right side. The lesion extends across the residual alveolar ridge onto the palate and onto the facial aspect of the ridge. The diagnosis is oral melanoma. Courtesy of Dr Carl Allen, Ohio State University. |
 | Media file 2: Male Japanese patient with extensive, black-pigmented and irregularly bordered macule in the maxillary labial mucosa and midline facial gingiva, (teeth 8 and 9). (The patient's fingers are depicted.) The diagnosis is oral melanoma. Courtesy Dr Bob Goode, Tufts University. |
 | Media file 3: Large, blue-black, irregularly bordered lesion on the upper lip of a male Japanese patient. The diagnosis is oral melanoma. Courtesy Dr Bob Goode, Tufts University. |
 | Media file 4: A polypoid mass. Rounded collections or nests of melanocytes fill the connective tissue and have tropism for the surface epithelium (hematoxylin and eosin, original magnification X2). This mass was excised from the lingual surface of the posterior mandible of an elderly man. The diagnosis is oral melanoma. |
 | Media file 5: A polypoid mass with tumor cells shows strong, positive staining with S-100 protein immunohistochemical stain (original magnification X2). The diagnosis is oral melanoma. |
 | Media file 6: Tumor cell cytoplasmic homatropine methylbromide (HMB-45) immunohistochemical staining (original magnification X40). The diagnosis is oral melanoma. |
 | Media file 7: Tumor cells show affinity for the surface epithelium (merging of tumor and epithelium). Cellular pleomorphism and smudged nuclei with pseudoinclusions are noted (hematoxylin and eosin, original magnification X10). The diagnosis is oral melanoma. |
 | Media file 8: Rounded nest of various sized melanocytes with nuclear pseudoinclusions (hematoxylin and eosin, original magnification X40). The diagnosis is oral melanoma. |
 | Media file 9: Two, diffusely bordered, dark gray macules in the left posterior buccal mucosa adjacent to molar teeth that have been restored. The diagnosis is an amalgam tattoo. |
 | Media file 10: Clinical photo of an irregularly shaped, tan-brown macule in the right side of the posterior hard palate. The diagnosis is oral melanotic macule. |
 | Media file 11: Clinical photo of the buccal mucosa of a middle-aged, black woman with a brown-black, irregularly bordered macule that arose suddenly. The patient was unaware of its presence. The diagnosis is oral melanoacanthoma. |
