E-mail: [e-mail] This study describes for the first time a case of coligranulomatosis in broilers in the state of Tocantins. Three males from a farm (flock of approximately 300 birds), with approximately 60 days of age, were sent to the Veterinary Pathology Laboratory of the Universidade Federal do Tocantins. The birds were necropsied and tissue samples were sent for histopathology. Grossly, significant lesions were firm nodules, whitish gray, measuring from 3 to 10 mm in diameter located in the serosal surfaces of the intestines and gall bladder. Microscopically, typical granulomas with eosinophilic necrotic centers surrounded by epithelioid cells and multinucleated giant cells with scattered heterophils were observed. No mycotic forms or alcohol-acid resistant organisms were observed in sections stained by periodic acid-Schiff and Ziehl-Neelsen, respectively. Based on lesions was diagnosed coligranuloma, a rare form of avian colibacillosis.
