Primary endobronchial schwannomas are extremely rare tumors that originate from Schwann cells. We report a case of primary endobronchial schwannoma. A 44-year-old woman, without respiratory symptoms, was presented with a nodule in the left main bronchus on her chest computed tomography scan. The nodule was removed by a rigid bronchoscopy with argon plasma coagulation. Biopsy confirmed the diagnosis of schwannoma. There was no recurrence during her 4-month follow-up.
