Abstract
A woman in her sixties had had a pigmented macule on her right sole for 10 years. At the initial examination, a pigmented macule with ulceration was found in her right sole. Dermoscopic examination showed irregular dots/globules in most parts. A diagnosis of malignant melanoma was established with histological examination of an excisional biopsy. Breslow's tumor thickness was 1mm. A sentinel node biopsy was performed with a positive result. Therefore, we performed right inguinal lymph node dissection. The histological specimen showed three micrometastases in the lymph nodes. In general, early palmoplantar melanomas exhibit parallel ridge patterns on dermoscopy, but some cases show irregular dots/globules in most parts of the lesion. In addition, we should consider the possibility of lymph metastasis in cases of thin palmoplantar melanoma.Skin Research, 13: 40-43, 2014
