title: [Mucinous adenocarcinoma of the prostatic gland. Histochemical and immunohistochemical studies].
abstract: We report a case of mucinous adenocarcinoma of the prostate gland in an 82-year-old patient who consulted for urinary discomfort. Rectal digital examination revealed a smooth tumor in the left lateral aspect. No bony metastases were observed and the prostate acid phosphatase levels were normal. The histological analysis revealed the typical group of tumor cells in abundant mucin with acid and neutral component disclosed by histochemical methods. The immunohistochemical analysis revealed the prostatic origin of the neoplasm, with tumor cell cytoplasm strongly positive for both prostate specific antigen and prostate acid phosphatase. This histological variant accounts for approximately 0.4% of prostatic adenomas. Only 50 cases have been reported in the literature.
