Small cell carcinoma of the lung presenting as chylous ascites: a unique case.

A 67-year-old female presenting with a history of weight loss and abdominal distension was noted on examination to have ascites. Paracentesis revealed a chylous ascites and chest radiography showed a right hilar enlargement with mid-zone infiltration. Abdominal computed tomography demonstrated retroperitoneal lymphadenopathy and biopsy of this showed small cell undifferentiated carcinoma. This appears to be the first documented association between metastatic small cell carcinoma of the lung and chylous ascites.
