A 60-year-old woman with superficial spreading melanoma in situ, measuring 2.5 mm in diameter, was examined. She had noticed a very small pigmented lesion 1.2 mm in diameter on her left lower leg in April of 1989. By April of 1990, it had grown to 2.5 mm in diameter. Its edge was irregular, and its color was variegated black to brown. Skin surface markings had disappeared in the center portion. Histopathologically, the lesion was asymmetrical. Atypical large cells nested in the lower epidermis and were scattered singly in the mid and upper epidermis, as seen in Paget's disease. At the periphery of the lesion, single large tumor cells were scattered in the mid epidermis. The tumor cells reacted to monoclonal anti-melanoma antibody HMB-45.

A 62-year-old male Turkish patient had a pigmented lesion on the sole with a 10-year history. It was an asymmetrical macular lesion with an irregular border and irregular brown pigmentation and had a diameter of 1.2 cm x 1.7 cm. Dermoscopy revealed a parallel ridge pattern and an abrupt cut-off of pigmentation on the upper edge. Histologically lentiginous hyperplasia decorated by innocent melanocytes and scattered melanocytic proliferation with slight to moderate cytological atypia were seen. Atypical melanocytes were very scattered and it was insufficient to call it a melanoma in situ. A second finding was a microvascular proliferation located in the papillary dermis. There was no sign of regression such as fibrous tissue or host reaction. Atypical melanosis of the foot has rarely been reported in the published work, which are from Japan and Korea. This case is presented to emphasize the significance of this rare entity which has recently been reported to be a very early phase of acral melanoma.
