[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. The average Breslow thickness at diagnosis is higher than in other melanoma variants. However, the tendency to lymph node metastasis is low.
