Omental metastasis with malignant ascites: an unusual manifestation of prostatic adenocarcinoma. Canadian Urological Association journal = Journal de l'Association des urologues du Canada [Can Urol Assoc J] Journal article

Omental metastasis with malignant ascites from prostatic adenocarcinoma is rare. This case report is about a patient who presented with a 24-hour history of a swollen right leg. Clinical examination revealed a hard prostate and blood biochemistry demonstrated an elevated prostate specific antigen level. A Doppler ultrasound scan excluded deep venous thrombosis, but a CT scan of the abdomen revealed marked para-aortic lymphadenopathy and prostate gland biopsy confirmed prostatic adenocarcinoma. The patient was treated with goserelin. Three years later, he presented with ascites and an omental mass. Histology of the omental mass showed metastasis from the prostatic adenocarcinoma. He was treated with second-line hormonal therapy but died after 4 months. We discuss the clinical progression, with a review of the literature.
