ABSTRACT
The challenge in daily routine is that pink tumors are difficult to differentiate from inflammatory, infectious or autoimmune diseases because they show overlapping clinical and dermoscopic criteria and vice versa. This is especially when a common disease, for example, eczema or psoriasis, presents with an unusual clinical pattern. In fact, amelanotic melanoma may clinically and dermoscopically resemble a solitary eczematous lesion, whereas a solitary psoriasis plaque may be confounded with a spitzoid tumor. The given history, topography, number and distribution, as well as clinical appearance are important features to be assessed before proceeding with the dermoscopic diagnosis. Once a given lesion has been clinically judged a tumor, further dermoscopic analysis should consider first the vascular morphology, second the architectural arrangement of vessels within the tumor, third the presence of specific pattern combinations, and fourth the presence of additional dermoscopic clues.
