【 摘 要 】

The parallel ridge pattern, characterized by a parallel band-like pigmentation of the ridges of the surface skin markings, represents the most important dermoscopic feature of in situ acral melanoma. A case of a young girl who showed a plantar pigmented brown macule likely due to prolonged contact with black rubber shoes, revealing a parallel ridge pattern on dermoscopy, is reported and discussed. Although parallel ridge pattern is highly suspicious of early melanoma, exogenous pigmentation should be considered as differential diagnosis in case of rapid onset acral pigmented macules.
