Endobronchial Mucosal Neuroma with Sarcoidosis

A first case of endobronchial mucosal neuroma with sarcoidosis is hereby reported. A 67-year female patient, who was diagnosed as sarcoidosis previously, was admitted to our hospital with symptoms of dyspnea, chest pain and fatigue. Middle lobe atelectasis and endobronchial lesion were observed in thorax computed tomography (CT). Fiberoptic bronchoscopy revealed polypoid lesions and histopathological examination of biopsy material showed clustered nerve bundles consistent with mucosal neuroma and non-necrotising granulomas consistent with sarcoidosis. Mucosal neuromas are pathognomonic features of multiple endocrine neoplasia (MEN) type 2B. But other components of MEN type 2B such as medullary tyroid carcinoma or pheochromocytoma were not detected in our patient. Hence, a diagnosis of solitary mucosal neuroma and sarcoidosis in the bronchi was made.
