A late manifestation of testicular seminoma in the bladder in a renal transplant recipient: a case report.

Abstract

An unusual case is presented of a renal transplant recipient on immunosuppressive medication who underwent orchiectomy for a testicular seminoma. Since the surgical resection plane showed seminoma cells, radiotherapy was applied to the para-aortic and inguinal regions. Tumor recurred in the bladder 3 years later as demonstrated by urine cytology and later by bladder biopsies. After chemotherapy, repeated bladder biopsies were normal and a complete remission was achieved. The possible metastatic pathways are discussed.
