¿Melanoma lentiginoso acral: metastásico, simultáneo, persistente? Persistent, simultaneous, metastasic, acral lentiginous melanoma?

Summary Acral lentiginous melanoma (MLA) represents 5% of all malignant melanomas, and has a frequency of loco-regional metastases greater than other subtypes of melanoma. In clinical practice we observed that a significant percentage of cases of MLA that recurrences in apparently healthy areas of skin, even after making excision with adequate safety margins, as in a case that we present. This could be generated by the presence of so-called “melanoma field cells” recently defined by Bastian.
