Abstract

A mottled black pigmented patch on the sole of the foot is reported. Clinically, the lesion closely mimicked acral lentiginous melanoma in situ. However, the histologic findings revealed melanocytic hyperplasia with minimal cytologic atypia confined to the epidermis. Irregular pigmented patches in the acral region comprise a heterogenous group of lesions that range from benign melanocytic hyperplasia to acral lentiginous melanoma.

摘要

据报道，足底出现一块斑驳的黑色色素沉着斑。临床上，该病变酷似原位肢端雀斑样黑色素瘤。然而，组织学检查结果显示为黑素细胞增生，细胞学异型性极小，仅局限于表皮。肢端区域的不规则色素沉着斑包括一系列不同的病变，从良性黑素细胞增生到肢端雀斑样黑色素瘤。
