| Abstract: | A relatively rare case of papillary adenocarcinoma of prostate is reported. The patient was a 49-year-old male. He presented with the chief complaints of micturition frequency, a feeling of residual urine and a burning sensation in urethra. There was no palpable abnormality in the prostate. Endoscopic examination revealed papillary tumors in the prostatic urethra and the anterior urethra, but no evidence of abnormality in the utricle. Both hematological examination and blood chemistry revealed no abnormalities; ACP, PACP and PAP were normal. The tumors were resected by TUR on March 8, 1982. Histopathological findings indicated papillary proliferation of single layer of columnar epithelium, with clear cytoplasm and nuclei with atypism distributed in the base. The tumors in the anterior urethra gave the same findings, and the diagnosis made was papillary adenocarcinoma which seemed to have originated from the prostatic duct. After operation, hormone therapy and chemotherapy with peplomycin were conducted. Eleven months after the operation, the remaining prostatic tissues including surgical capsule were resected as completely as possible. Histopathological findings revealed only atrophic prostatic tissues without any remaining tumor. The hormone therapy was discontinued. Presently, 19 months has elapsed since the first TUR. His micturition condition is good without evidence of recurrence or metastasis. |
