Acral lentiginous nevus

In non-Caucasians, malignant melanoma most frequently affects the sole of the foot. To improve the prognosis in such patients, accurate diagnosis of early lesions is extremely important, and, to avoid potentially mutilating surgery, it is equally important to identify benign acral nevus. Clemente and colleagues recently proposed a new clinicopathological entity, designated acral lentiginous nevus (ALN) of the plantar skin. The clinical and histopathological characteristics of these nevi enable clinicians to distinguish them from ordinary nevi and melanoma. We report four additional cases of ALN, which can be classified as belonging to the "pseudomelanoma" group.
