title: [Prostatic cancer with cystic formation: a case report].
abstract: A 60-year-old man was admitted to our hospital with the chief complaints of dysuria and sense of abdominal fullness. On digital rectal examination, an enlarged prostate with a smooth surface and elasticity was palpated. The concentration of prostate specific antigen (PSA) was elevated to 78 ng/ml. Pelvic computed tomographic (CT) scan and magnetic resonance imaging (MRI) revealed a large prostate, 8 cm in diameter, with a cystic mass, and extra-iliac lymph node swelling. On needle biopsy of the prostate and cyst, the histology was poorly differentiated adenocarcinoma, and the aspirate comprised bloody fluid with a negative test for cytology. He was diagnosed with prostatic cancer of T4N3M0. This is the 19th case of prostatic cancer with cystic formation reported in Japan.
