[A case of localized pleural mesothelioma containing a wedge-shaped area of aeration].
A 32-year-old man was admitted to our hospital because of an abnormal shadow on the chest X-ray film, which was detected on mass survey. The chest X-ray film on admission revealed an irregular mass shadow in the pleural layer between the left upper lobe and the lower lobe, and this shadow had a wedge-shaped area of aeration inside it. Needle biopsy under ultrasonography suggested a localized pleural mesothelioma. Surgery to resect the tumor revealed that it was pedunculated and had developed from the pleura of the left S5 segment. The resected specimen showed lung tissue invaginating into the tumor through a concave area of the tumor. The chest X-ray findings of this case are very unusual, and we were unable to find a similar case of localized pleural mesothelioma in the literature.
