Abstract

The paper presents a case of a single bronchocele (bronchogenic retention cyst) caused by a typical carcinoid that was observed for a long time. During the initial complex examination, including computed tomography with intravenous contrast, fibrobronchoscopy, and immunological and bacteriological examinations of tuberculosis, there were no changes for the oncological and infectious nature. The changes were interpreted as the result of a postponed nonspecific inflammatory process. Most of them were monitored using chest X-ray and the changes were stable. After 15 years, a control chest X-ray revealed an increase in the size of the compaction in the lung and the appearance of a mass with calcification in the medial sections of the compaction zone. Additional examination, including computed tomography with biopsy, determined that the obstruction of the bronchus was caused by a neoplasm [according to histological examination (typical carcinoid)].

It should be noted that the initial detection of negative study results requires oncological alertness and periodic examinations in dynamics.
