[Cutaneous metastasis revealing a testicular choriocarcinoma]

Skin is an uncommon site of metastatic disease when compared to other organs or sites in the body. Occasionally, cutaneous metastasis may be the first clinical manifestation of a clinically silent, visceral malignancy of unknown origin. We report the case of a 25 year old man with a single perineal reddish nodule. Microscopic examination of the cutaneous nodule revealed the typical histologic features of a testicular tumor with metastases to liver and lungs. The patient died four month after the diagnosis due to complications of metastatic disease.
