Extract

Dermoscopy has clearly improved diagnosis of pigmented skin lesions. By virtue of the special architecture of the epidermis on palms and soles, these locations have specific patterns. Parallel ridge pattern (PRP), a bandlike pigmentation on the ridges of the surface skin markings, is a highly characteristic dermoscopic pattern of acral melanoma. However, it can be detected in a few benign conditions.
