Cellular schwannoma is a rare variant of schwannoma, showing high cellularity and a low mitotic index. A 64-year-old man was admitted to our hospital with a 2-month history of productive cough. Chest computed tomography showed an endobronchial tumor with complete atelectasis of the right lower lobe. Bronchoscopy showed an endobronchial tumor occluding the intermediate bronchus that was diagnosed as a cellular schwannoma on biopsy and was successfully excised with a right lower sleeve lobectomy to preserve the middle lobe. The postoperative course was uneventful, and the patient remains well with no sign of recurrence at the 7-year follow-up.
