Dermatosurgery is the primary treatment for subungual melanoma, aiming to remove the cancerous nail, nail bed, and surrounding tissue, often involving digit amputation (finger/toe) or wider excision (Wide Local Excision/Mohs surgery) for deeper/larger tumors to achieve clear margins, with further treatments like radiation, chemotherapy, or immunotherapy used if it has spread, though doctors increasingly favor limb-sparing options like skin grafts when possible, especially for early-stage cases.

Early diagnosis is crucial, but dermatosurgical management focuses on complete removal of the lesion, with a trend towards conservative, function-preserving techniques when appropriate, supplemented by other therapies if needed.
