Is nail melanoma really rare?

Nail melanoma is a particular form of melanoma defined by its specific location and its particular molecular pathologic characteristics. It is often diagnosed late or misdiagnosed rendering its prognosis poor. Nail melanoma awareness is extremely important for a timely diagnosis and correct treatment. Wide local excision with a 6mm safety margin around the anatomical border of the nail unit and 10mm around a Hutchinson sign is curative for in situ and early invasive subungual melanoma.
