Background. An emphysematous bulla is considered a risk factor of lung cancer. Case. A man in his 40s had a history of video-assisted thoracoscopic surgery for right spontaneous pneumothorax in his 20s but had continued to smoke. After an abnormal shadow was noted on chest X-ray during a medical examination, he was referred to us. Computed tomography (CT) showed a right emphysematous cystic lesion 9.0×5.0×10.0 cm in size and a 2.4 cm solid nodule on a part of the cyst wall. Although lung cancer originating near the bulla wall was suspected, a postoperative foreign body and chest wall tumor could not be ruled out. After a CT-guided core needle biopsy was performed, pneumothorax occurred. Because a histopathological study revealed adenocarcinoma, he was diagnosed with primary lung cancer originating near the emphysematous bulla wall. Subsequently, right upper lobectomy was performed. The postoperative course was uneventful. Conclusion. We experienced a case of lung cancer originating near the bulla wall with atypical findings of clinical imaging.
