Dermoscopic evaluation of nonpigmented lesions: Amelanotic melanoma and basal cell carcinoma
Dermoscopic evaluation of nonpigmented lesions: Amelanotic melanoma and basal cell carcinoma
Amelanotic melanoma (A) and basal cell carcinoma (B). Using the "prediction without pigment" algorithm, dermoscopy reveals ulceration (B), white clues (A, B), and polymorphous vessels (A, B). Thus, with any of these structures, a biopsy should be performed.
