Chylous ascites secondary to malignancy is usually associated with lymphoproliferative disorders such as Hodgkin's and non-Hodgkin's lymphoma. Other neoplasms include carcinoma of the pancreas, stomach, breast, ovary, carcinoid, kidney, and prostate. Chylous ascites secondary to carcinoma of the prostate is, however, extremely rare. The prognosis in these patients is usually poor and most patients die within a few months after diagnosis.
