Background. Myxofibrosarcoma is a relatively rare soft tissue tumor appearing most commonly on the limbs of elderly patients. There are limited reports about its pleural metastasis. Case. An 86-year-old male with a past history of myxofibrosarcoma in the left scapular region visited our department with a chief complaint of dyspnea. A plain chest X-ray showed right pleural effusion and a chest computed tomography (CT) scan revealed pleural tumors with effusion. After admission to hospital, with a cytological analysis of the pleural aspirate, which proved inconclusive, we performed thoracoscopy under local anesthesia, which revealed red pleural nodules. A histopathological examination confirmed that the nodules were composed of metastatic myxofibrosarcoma. Conclusion. When pleural effusion cytology is inconclusive in a patient with a past history of myxofibrosarcoma, thoracoscopy under local anesthesia can be useful for the diagnosis of pleural metastasis.
