CA 125が腫瘍マーカーとして有用と考えられた男子原発性尿道腺癌の1例

Abstract

A case of primary adenocarcinoma of the male urethra with high CA125 level is reported. A 66-year-old man was admitted to our hospital with dysuria and perineal discomfort. The urethrocystogram revealed an irregular urethral margin in the bulbo-membranous urethra. Computer-tomographic (CT) scan and transrectal ultrasonography revealed an irregular mass between the urethra and rectum. Cytologic examination of the urine was negative for malignancy. Endoscopy revealed an irregular bulbo-membranous urethra with a small papillary lesion. Transurethral biopsy was performed and histological diagnosis was adenocarcinoma. The patient rejected surgical treatment and radiotherapy was performed. However, the disease progressed and the patient died from liver metastasis six months later. We considered that CA125 was valuable as a tumor maker in this patient.
