A 70-year-old man was referred in May 1990 for a left lower ureteral stone. Digital rectal examination demonstrated a moderately enlarged prostate with an irregular surface. Serum prostate specific antigen (PSA) was 6.6 ng./ ml. Ultrasound guided biopsy of the prostate aiming toward the hypoechoic lesion showed nodular hyperplasia. Three years previously the patient had undergone radical gastrectomy for signet-ring cell carcinoma of the stomach (stage pT3N2M0) followed by adjuvant chemotherapy. Followup computerized tomography and radioisotope bone scan revealed absence of tumor. The patient subsequently underwent transurethral resection of the prostate in February 1991 for increasing lower urinary tract symptoms and a PSA of 9.7 ng./ml. Pathological examination demonstrated poorly differentiated signet-ring cell carcinoma with negative PSA staining (figs. 1 and 2). Staging computerized tomography showed infiltrative tumor in a cul-de-sac with direct invasion of the prostate. The patient was managed conservatively. Nine months later he underwent exploratory laparotomy for intestinal obstruction. Generalized tumor seeding to the omentum and cul-de-sac was confirmed at that time.
