Case report:
    A 95-year-old male has underlying disease of severe prostate hyperplasia, abnormal serum prostate-specific antigen(PSA: 18.41ng/dl) and hardness digital rectal examination were noted. Because of multiple comorbidities and bed ridden status, further prostate malignancy survey cannot be performed. Patient has long-term Foley catheteration for difficult urinary voiding treatment. He hospitalized for antibiotic treatment under the impression of urinary tract infection with initial present by gross hematuria and pyuria. However, painful priapism with adequate glans circulation noted for one week . Bedside cavernosal aspiration revealed no blood content but only debris. No evidence of sickle cell anemia via hematological study. Dorsal slit with cavernosal biopsy was performed for symptoms relief and differential diagnosis under local anesthesia. The priapism and pain improved after the shunting procedure was done.
    The following pathological report of biopsy tissue showed poorly differentiated adenocarcinoma. Metastatic prostate adenocarcinoma was proved by the immunohistochemical(IHC) stain which disclosed P504S positive. Further bone scan revealed no obvious bony metastasis, patient cannot complete pelvic magnetic resonance imaging(MRI) study because of poor general conditions. This patient died of another episode of pneumonia related sepsis progression l month later.
