Subungual (under the nail) melanoma

Subungual melanoma is a rare type of skin cancer that occurs under the nails, often affecting the fingers or toes. It usually appears as a dark stripe or discoloration, which can be mistaken for a bruise or nail fungus. This condition can develop from melanocytes, the pigment-producing cells in the skin. Early detection is crucial, as it can be aggressive and may spread to other parts of the body if not treated promptly. If you notice unusual changes in your nails, such as persistent discoloration, it’s important to consult a healthcare professional for evaluation.
