Radiologic appearance of a bronchial granular cell tumor with secondary obstructive changes

Granular cell tumor in the pulmonary tree

Granular cell tumors are often benign growths of the tongue, dermis, and subcutaneous tissues. Rarely, we see production in the pulmonary system. These schwannian and histiocyte origin tumors in the lungs are called pulmonary granulocyte tumors. While granular cell tumors are rare, pulmonary granulocyte tumors are even rarer, with less than eighty-five cases described since the 1930s. Herein, we introduce these rare growths and provide a review of known epidemiological evidence and pathophysiology.

Pleural-based granular cell tumor

Granular cell tumors are rare tumors of Schwann cell origin that arise from tissues of neural crest and mesenchymal origin. We report the clinical, radiographic, and pathological features of a pleural-based granular cell tumor in a 60-year-old African American man.

Primary bronchial granular cell tumor in an adult male

We report a rare case of granular cell tumor arising in the left lower lobe (LLL) bronchus with secondary obstructive change in a 60-year-old male. The patient was found to have a nodule in the LLL on a computed tomography scan, three months prior to his presentation to the Asan Medical Center. Bronchoscopic biopsies revealed a granular cell tumor. After undergoing LLL lobectomy with bronchoplasty, the patient has not experienced any tumor recurrence.
