A case of prostate cancer presenting as a symptomatic abdominal mass.
An 80-year-old man presented to our hospital complaining of an abdominal mass. On physical examination, a hard fist-sized mass was noted in the right lower abdomen. Needle biopsy of the prostate and abdominal mass showed moderately differentiated adenocarcinoma. The chest roentgenogram revealed multiple lung metastases. Clinical diagnosis was T3N3M1, stage D2. Serum prostate specific antigen (PSA) level (8,600 ng/ml) normalized after 3 months of anti-androgen therapy. Lung metastases disappeared after 11 months, while the abdominal mass was reduced to 25% of the pretreatment size after followup of 30 months.
