title: [Bronchial carcinoid discovered due to repeated pneumonia in the lingular division of the left lung; report of a case].
abstract: Bronchial carcinoids are relatively rare, low-grade malignancies. Here we report a case of a bronchial carcinoid found by repeated pneumonia in the lingular division of the left lung. A 34-year-old man was referred to our hospital because of an abnormal shadow detected in an annual checkup. A chest computed tomography (CT) showed an infiltrative shadow in the lingular division. Two months later, a follow-up CT showed the shadow had remarkably improved. Two years after the 1st detection, an annual checkup revealed an abnormal shadow in the same lesion again. A chest CT showed not only an infiltrative shadow in the lingular division, but also a solid mass with calcification in the lingular bronchus. A bronchoscopy revealed an obstruction of the left upper lobe bronchus by a vascularized polypoid tumor. A transbronchial biopsy indicated a presence of a carcinoid, and a resection of the left upper lobe was performed. A histopathological examination showed that it was a typical carcinoid. The patient has been free of recurrence for 2 years since surgery. This is a case with repeated pneumonia and atelectasis caused by a bronchial carcinoid.
