title: Transbronchial needle aspiration.
abstract: To determine the value of transbronchial needle aspiration biopsy in the diagnosis of sarcoidosis, we reviewed a one-year experience of consecutive patients with sarcoidosis presenting with hilar and/or paratracheal adenopathy. The sensitivity of transbronchial needle aspiration biopsy in obtaining noncaseating granulomas was 90%. This yield exceeds that of most published reports of transbronchial lung biopsy and bronchial mucosal biopsy and suggests that transbronchial needle aspiration biopsy may be a valuable diagnostic tool in the evaluation of these forms of sarcoidosis.
