Extract

This review of previously acquired data reports that the use of a 2-step algorithm and pattern analysis in dermoscopy can identify benign cutaneous melanoacanthoma in patients with seborrheic keratosis.

Cutaneous melanoacanthoma (CM) is traditionally considered to be a heavily pigmented variant of seborrheic keratosis (SK).1 The characteristic histologic feature of CM is the presence of large, highly dendritic, melanin-rich melanocytes spread throughout an acanthotic epidermis.2 Owing to their pigmentation, CMs may mimic the clinical appearance of melanoma.1 Although the dermoscopic features of SK are well defined, little is known about the dermoscopic features of CM.3,4 Our objective was to evaluate the clinical and dermoscopic features of CM.
