Abstract

Acral lentiginous melanoma has a poor prognosis, because it has relatively short radial growth phase than lentigo maligna melanoma does. A 50 year-old female was presented with a 4X5cm-sized irregularly pigmented patch developed on the left palm. Initial punch biopsy examinations revealed atypical melanocytes only in the epidermis. But, after complete excision, melanoma cells were also observed in the upper dermis. We report an unusual case of acral lentiginous melanoma which showed vertical growth phase after twenty years of radial growth phase.
