Objective: Carcinoid tumors are rare malignant tumors of the lung and constitute 20% of all lung carcinomas. It is often seen as endobronchial lesions and is diagnosed by bronchoscopy. Recommended treatment is resection and mediastinal lymph node dissection. 5-year surveillance is 100% in patients who diagnosed with typical carcinoids. In this case report, we present a case in which we detected a typical carcinoid tumor incidentally in the resection tissue of the patient who admitted to our clinic due to recurrent spontaneous pneumothorax and we detected giant bullae. Case: A 69-yearold female patient was admitted to the emergency service with the complaint of dyspnea. She had pulse of 88 beats/min, arterial blood pressure 132/77 mmHg, saturation 94% with O2. Breathing sound was not heard from the right hemithorax on auscultation. It was learned that he had spontaneous pneumothorax on the right side ten months ago. Tube thoracostomy was applied to the patient, when total pneumothorax was seen on the right side of thorax on posteroanterior chest radiography. Thorax computed tomography showed a few bullous lesions in the anterior part of the right hemithorax, the largest of which was 9.5 cm in size, containing thin septations, but no other nodular lesions were observed. Videothoracoscopic bulla resection was performed on the patient. The patient was discharged on the 5th postoperative day without any complications. In histopathological examinations of the resection tissues, typical carcinoid tumor in 1 focus and tumorlet in 4 foci were detected, except bulla. The patient is in the third postoperative month and is being followed up from the polyclinic. Conclusion: Bullae can mask small tumoral lesions as they cause compression in the adjacent lung parenchyma. As can be seen in our case, it should be kept in mind that a carcinoid tumor may appear unexpectedly, accompanying spontaneous pneumothorax.
