RESUMO
We present a case of primary adenocarcinoma of the prostate with mucinous feature. Mucinous adenocarcinoma (MC) of the pros¬tate gland is rare morphological variant of Prostate carcinoma characterized by pools of extracellular mucin in >25% of tumor. A 72-year-old male presented to our hospital with urinary frequency, nocturia and voiding difficulties;on digital rectal examination enlarged prostate was observed without any palpable nodule. on Ultrasonography hypoechoic lesion was observed in left lobe of prostate suggestive of prostate tumor. A transurethral resection of prostate confirmed the diagnosis of Prostatic adenocarcinoma with mucinous features and Gleasons score 9(4+5). We report the cases due to the aggressive beahviour and uncommon diagnosis of mucinous variant of adenocarcinoma of the prostate. But it is seen that its proper diagnosis and treatment significantly contribute to favourable prognosis
