In populations with darker skin, melanoma occurs most frequently in acral areas, with a particular predilection for the soles of the feet. In Japanese, almost one-half of cutaneous melanomas occur in acral areas and approximately 30 percent affect the sole [1]. The prognosis of acral melanoma is generally poor, mainly as a consequence of a delay in diagnosis [2,3]. Dermoscopy, a noninvasive technique performed by a handheld instrument called a dermatoscope, increases the clinician’s diagnostic accuracy for pigmented lesions of the palms and soles and may help in the recognition of acral melanoma at an early, curable stage [4,5].

This topic will review the dermoscopic features of melanocytic and nonmelanocytic pigmented lesions of the palms and soles and the dermoscopic criteria for differentiating benign melanocytic nevi from early melanoma. The principles of dermoscopy and the use of dermoscopy for the evaluation of lesions located on the nonglabrous skin, face, mucosal surfaces, and nails are discussed separately. Dermoscopic algorithms for skin cancer triage are also discussed separately.
