Gross painless transudative ascites in a patient with ovarian cancer.

Transudative ascites are a rare entity in cancer which may sometimes make their diagnosis difficult. Here, the authors report an unusual case of transudative ascites in a 50-year-old woman with ovarian cancer. The patient first presented with progressive painless gross transudative ascites for the past five months with no associated nephrotic syndrome or liver cirrhosis, and chylous ascites developed on day 14 of the admission. The ascites were transudate with serum-ascites albumin gradient (SAAG) above 11 g/L. Repeated screening of cancer cells from ascites revealed adenocarcinoma originated from ovary.
