Malignant ascites as only manifestation of metastatic prostate cancer

Prostate cancer is the most common malignancy in men in the US. Both at dia gnosis and throughout the disease progression it can metastasize to multipl e organs (bone and lymph being the most common). Effusions (either pleural or abdominal) are relatively uncommon, but usually occur as a result of sof t tissue lesions. Herein we report on a patient with androgen independent p rostate cancer and an elevated PSA with disease confined to ascites of the abdomen.
