[Desmoplastic and neurotropic subungueal melanoma].
BACKGROUND
Desmoplastic and neurotropic melanoma is rare and involvement of the subungual skin is an exceptional finding.


METHODS
We report the second case of desmoplastic and neurotropic subungual melanoma in the literature occurring in a 71-year-old woman.


CONCLUSIONS
In our patient, the histological diagnosis of desmoplastic melanoma was particularly difficult because of the exceptional involvement of the subungual skin. Microscopic neurotropism and immunohistochemical studies were the clues in diagnosing desmoplastic melanoma.
