Abstract

<p>Adenocarcinoma of the rete testis is a rare malignant tumor with poor prognosis. We report a case of adenocarcinoma of the rete testis. A 55-year-old man became aware of discomfort in the right scrotum. Negative results were obtained for the serum markers AFP, β-human chorionic gonadotropin (β-HCG), and LDH. Computed tomography (CT) showed enhancement of the right testis. Radical orchiectomy was performed. Immunohistochemical examination of the resected specimen showed positive results for CEA, and adenocarcinoma of the rete testis was diagnosed. Serum CEA level was elevated. CT showed swelling of the para-aortic lymph nodes. Retroperitoneal lymph node dissection (RPLND) was performed, and serum CEA then normalized. The patient developed penile metastases 4 months after RPLND, and serum CEA level again increased. Total penile resection was performed. TIP (Paclitaxel, Ifosfamide, Cisplatin) therapy was started after lung metastasis and increased serum CEA were identified. CT after 2 cycles of TIP therapy revealed disappearance of lung metastasis and normalization of serum CEA. Five months later, CT showed recurrence of lung metastases.</p>
