“…There are approximately 50 case reports of endobronchial schwannomas in the Japanese literature 1 and only scattered case reports from other countries. 4 Similar to our patient, there were no symptoms attributable to the 2 lesions. 8 Clinical presentations of endobronchial schwannomas have included massive hemoptysis, postobstructive pneumonia, cough, and dyspnea.…”

Schwannomas are benign nerve-sheath tumors that arise from Schwann cells. They can present as endobronchial lesions with symptoms of obstruction and hemoptysis. We describe the first case of multiple endobronchial schwannomas at 3 different sites in a single patient. The autofluorescence ratio was <0.5 for 2 of 3 lesions. The optimal follow-up and treatment plan for these lesions remain unknown, especially in asymptomatic patients.

“…Although it is a rare condition, endobronchial schwannomas have been previously reported in the literature. 4 We describe a case of triple endobronchial schwannomas discovered incidentally during a flexible bronchoscopy. 2,3 Bronchoscopy typically reveals a solitary lesion in the airway.…”

“…Harada et al speculated that multiple endobronchial schwannomas might be caused by the proliferation of Schwann cells resulting from cigarette smoking followed by inflammation of the bronchial mucosa. 12 The presence of smoking history in all patients (three current and one former smoker) reported by Suzuki et al supported this speculation. 13 In contrast to these observations, our case denied active or passive cigarette exposure.…”

“…11 The other was reported in the English literature in which the tumors were located in the right middle/lower lobe bronchi and in the right basalis anterior/ basalis lateralis segmental bronchi. 12 In our case, the tumor nearly completely obliterated the left upper lobe bronchus and the other one was located at the bifurcation of right upper lobe bronchus.…”

The main symptoms of patients with endobronchial schwannoma are dyspnea, wheezing, cough, sputum production, and hemoptysis.…”
