In a male, 4 months old, organic chicken carcass, irregular plaques were observed in the skin.

The plaques were soft, of increased skin thickness and, when cut, were yellowish in color and edematous with the presence of small nodules of 2-3 mm of diameter. Histopathological study showed granulomatous inflammatory lesions. Grocott staining to identify the presence of hyphae in the center of the granuloma was performed with a positive result. A diagnosis of fungal granulomatous dermatitis was established.
