Subungual Acral Lentiginous Melanoma of the Fifth Toe.

Acral lentiginous melanoma is rare in Caucasians, but it is the most common among individuals with a higher phototype, such as Blacks and Asians. It is usually presented under the palmoplantar and/or nail region. Subungual melanoma is an acral lentiginous melanoma subtype in which the initial diagnostic approach does not have a consensus. We report a case of a woman with tumoral melanocytic lesion on the fifth toenail, of insidious growth, where the amputation of the nail apparatus technique was used as an excisional biopsy for an extensive lesion. The patient is followed up in an outpatient clinic setting without lymph node or distance metastasis.
