Abstract

BACKGROUND:

Using dermoscopy (dermatoscopy, epiluminescence microscopy), malignant skin tumors can be detected earlier and unnecessary excisions of benign tumors can be avoided.

OBJECTIVE:

Description of the dermoscopic vascular patterns of an amelanotic melanoma and a porocarcinoma.

METHODS:

Dermoscopy of an amelanotic melanoma and a porocarcinoma at 10-fold magnification.

RESULTS:

On dermoscopy polymorphous vascular patterns with pinpoint and hairpin-like vessels were seen.

CONCLUSION:

A reddish tumor without any pigmented network, globules or streaks but with polymorphous vascular patterns must be considered a malignant melanocytic or nonmelanocytic skin tumor.
