[Meigs syndrome presenting as diaphragmatic pleural nodules].

A 52-year-old woman was admitted to our hospital because of non-productive coughing and dyspnea on exertion. A chest X-ray film revealed a moderate pleural effusion. The effusion was persistent and progressive in spite of repeated thoracentesis. Because examinations of the effusion did not result in a specific diagnosis, thoracoscopy was done under local anesthesia. Two nodules were found in the surface of the diaphragmatic pleura. Examination of biopsy specimens revealed mesothelial hyperplasia and lymphatic duct proliferation without malignant or granulomatous lesions. Systemic examinations revealed a tumor in the right ovary. The tumor was removed, and examination revealed that it was a serous adenofibroma without malignant lesions. Meigs syndrome was diagnosed. The pleural effusion disappeared quickly, two weeks after the operation. We know of no previous report of diaphragmatic pleural nodules in a case of Meigs' syndrome. Meigs' syndrome should be considered in the differential diagnosis of pleural nodules.
