Sarcoid granuloma-like lesions in the lungs of broiler chicks.

ABSTRACT

Sarcoid granuloma-like lesions were observed in the lungs of two broiler chicks showing depressed growth. Multinucleated giant cells in the lesions often contained foreign bodies comprising amorphous and laminated material. These were morphologically similar to Schaumann bodies found in human sarcoidosis. This is the first report of sarcoid granuloma-like lesions and Schaumann body-like material in chickens.
