[Mixed desmoplastic melanoma].

Desmoplastic melanoma is a rare presentation of melanoma with a different clinical behavior compared to other histological variants. Its diagnosis in early stages is a challenge due to its variable clinical presentation, with a predominant dermal component and the frequent absence of pigment. Its histology is divided into pure and mixed type, and this classification has important prognostic implications.
