Abstract
A 72-year-old woman had undergone left upper lobectomy of the lung for a rapidly growing metastatic solitary fibrous tumor (SFT). Chest X-ray was normal on POD1, but the well defined nodule appeared in the left upper lung field on POD7. We thought that it represented a careless oversight or a rapid recurrence of SFT, and performed further partial resection of the nodule on POD14. However, histopathologic examination led to its identification as a subpleural hematoma. Subpleural hematoma should be detected at the end of surgery to avoid its misdiagnosis as a careless oversight or a rapidly growing recurrence.
