Ascites and lower limb edema in a patient with a history of intra-hepatic cholangiocarcinoma and breast cancer raised suspicion of cancer recurrence. Although CA 125 and CA 19.9 were elevated and initial cytologic findings for the ascitic fluid were consistent with this diagnosis, further tests revealed that the patient suffered from proteinlosing enteropathy, a benign, unusual condition.
