[Metastatic pure testicular seminoma of the skin].

Seminomas are germinal tumors from testicular cells in men. Cutaneous metastasis are very rare. The authors report the case of a 56-year-old male patient admitted for treatment of an enlarged left testicular mass. Physical examination revealed a cutaneous nodule on the right side of the back. Histopathologic examination of both orchiectomy materiel and cutaneous lesion revealed pure seminoma. Chest and abdomen-pelvis CT revealed a pulmonary metastatic nodules, enlarged para-aortic lymph nodes and metastatic lesions in the adrenals glands. The patient died six months after diagnosis due to complications of metastatic disease despite adjuvant chemotherapy. To our knowledge, we report the first case demonstrating that seminoma may spread to skin.
