[Case report of malignant sertoli cell tumor]

Malignant sertoli cell tumor is a rare disease and only a few cases have been described previously. We report a terminal case of malignant sertoli cell tumor. A 38-year-old male visited a hospital with a complaint of swelling his left testis. He underwent high left orchiectomy. His pathologic diagnosis was suspected seminoma, and all tumor markers (LDH, HCG, AFP) were negative, and CT imaging confirmed clinical stage 1 (pT1N0M0S0). One year later, a CT scan showed a small retroperitoneum lymph node swelling. Four months later, these lesions increased to 55 x 45 x 70 mm in diameter. He received 3 courses of chemotherapy with BEP (bleomycine, etoposide, cisplatin), but, lymph node size did not change. After he underwent a CT guided lymph node biopsy, his pathologic diagnosis was viable embryonal carcinoma. He then came to our hospital. We selected CPT-11 and nedaplatin for his salvage chemotherapy, but lymph node lesions did not change. After he received 3 courses of chemotherapy, we performed retroperitoneal lymphadenectomy. His pathologic diagnosis was viable sertoli cell tumor, malignant type. After 30 days, he had multiple liver metastases ane died 27 months after orchiectomy. All tumor markers were negative in his all clinical courses.
