Unusual presentations of benign intrathoracic neurogenic tumors.

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.
