title: Unusual presentations of benign intrathoracic neurogenic tumors.
abstract: Three patients with benign neural sheath tumors (two neurofibromata, one schwannoma) are reported here. One is known to have von Recklinghausen's disease. All presented in an atypical manner providing a diagnostic challenge. The series comprises one patient with a schwannoma of the left vagus nerve, one with submucosal neurofibromata of the lower one-third of the esophagus and one with an endobronchial neurofibroma. The plain film findings suggested aortic aneurysm, esophageal varices and endobronchial carcinoma respectively.
