[A case of gastric cancer with bilateral chylothorax]

The patient, a 77 year-old woman, visited our hospital with chief complaints of coughing and dyspnea. Chest radiography revealed bilateral pleural effusion especially on the right side, and she was admitted to our hospital to undergo a more thorough examination. The pleural effusion was identified as chyle. In cytodiagonosis, a number of adenocarcinoma cells in clumps were detected. After admission, her general condition worsened, and she died. Her condition was diagnosed as advanced gastric carcinoma on pathological dissection. Generally malignant lymphoma is most often reported as a cause of non-traumatic chylothorax. Because gastric carcinoma associated with bilateral chylothorax is very rare, we report the results of our study with some discussion based on a review of the literature.
