This case describes the history of disease of a 53-year old man, who has been treated for a putative recurrent nailbed granuloma of the right big toe since 1996. In 2000 an enlarged inguinal lymph node was excised. The light microscopic examination showed a metastasis of a malignant melanoma. In 2003 we received a tumor of the right big toe for histopathological examination. The histological and immunohistochemical results proved a dermal chondroid melanoma. This extremely rare variant of malignant melanoma occurs particularly in subungual location and is possibly related to a previous trauma. We discuss the spectrum of differential diagnoses and the importance of immunohistochemistry.
