Background:Using dermoscopy (dermatoscopy, epiluminescence microscopy), malig nant skin tumors can be detected earlier and unnecessary excisions of benign tum ors can be avoided. Objective:Description of the dermoscopic vascular patterns of an amelanotic melanoma and a porocarcinoma. Methods:Dermoscopy of an amelano tic melanoma and a porocarcinoma at 10-fold magnification. Results:On dermosco py polymorphous vascular patterns with pinpoint and hairpin-like vessels were s een. Conclusion:A reddish tumor without any pigmented network, globules or stre aks but with polymorphous vascular patterns must be considered a malignant melan ocytic or nonmelanocytic skin tumor.
