Chylous ascites due to signet ring cell gastric adenocarcinoma

Chylous ascites is a rare presentation of peritoneal effusion. The signet ring cell gastric adenocarcinoma is also relatively rare presentation of gastric cancer. We present a quite rare case of chylous ascites associated with signet ring cell gastric adenocarcinoma. Case report: a 47-years-old Caucasian man presented to our emergency department with abdominal distention. The abdominal ultra-sound showed high volume ascites and the diagnostic paracentesis revealed milk-like peritoneal fluid rich in triglycerides. He was underwent to medium chain triglycerides based diet, total parenteric diet and treatment with somatostatin without response. Due to presented digestive hemorrhagic events, upper digestive endoscopy was performed and revealed signet ring cells gastric adenocarcinoma on biopsy. The patient died in disseminated intravascular coagulation context. Conclusion: chylous asicites is a rare presentation of ascites and it may be associated with abdominal neoplasm. The prompt diagnosis is important for optimize the etiology evaluation and therapeutically approach.
