The name of pluripotential melanoblastoma has been proposed for the variants that include divergent cel-lular differentiation lines, meaning that the tumor recapitulates the potentialities of the ectomes-enchyme-neural crest cells committed to melanocytic differentiation.5 Dermal dendrocytes seem to encompass a dou-ble population of dermal-resident cells that, accord-ing to the literature, include CD34+ cells and factor XIIIa-positive 2 cell types apparently have different resident sites and function.6-8 Lesions related to thes
