Melanoma Under the Nails
Melanoma under the nails, known as subungual melanoma, is a relatively uncommon form of skin cancer. It primarily affects individuals with darker skin pigments, such as those of African American heritage. The initial sign of subungual melanoma is typically a discoloration in brown or black, often mistaken for a bruise. However, if detected early, the prognosis for recovery from this type of melanoma is generally favorable. Doctors can confirm the diagnosis through a biopsy, which involves removing or softening the nail to extract a segment of skin for examination by a pathologist.
Melanoma in the Mouth
Melanoma in the mouth, also known as oral cancer, is characterized by the development of a tumor on the surface of the tongue, mouth, lips, or gums. Although tumors can also occur in the salivary glands, tonsils, and pharynx, these locations are less common and typically associated with a syndrome. Symptoms of oral melanoma include the presence of red or white patches on the lining of the mouth or tongue, as well as the formation of ulcers, lumps, and pain experienced while eating and swallowing. Additionally, oral pigmentation may manifest, with colors ranging from light brown to blue-black, red, or purple. Similar to skin melanomas, oral melanomas often exhibit multiple colors.
