[A case of sarcoidosis with an endobronchial polypoid lesion]

A 59-year-old woman complained of impaired vision. She visited an ophthalmologist and glaucoma was diagnosed. In July 200X, she was admitted to our hospital for further examination. Chest radiography and CT showed lymphadenopathy in the mediastinum and bilateral hilum. Bronchofiberscopy revealed mucosal hypervascularity and a polypoid lesion at the orifice of the left B8a. A transbronchial biopsy specimen of the polypoid lesion showed non-caseating epithelioid cell granuloma. On bronchoalveolar lavage, both the proportion of lymphocytes and the CD 4/8 ratio had increased. We diagnosed sarcoidosis with an endobronchial polypoid lesion. The patient has been observed without therapy since, and after a year the polypoid lesion is the same size on 3D CT scans. This is a very rare case of endobronchial sarcoidosis presenting as a polypoid lesion.
