Dermatitis fúngica en un pollo
La piel está incrementada de espesor y las placas son blandas, amarillentas al corte y de aspecto edematoso con la presencia de pequeños nódulos de 2-3 mm de diámetro. El estudio histopatológico evidencia lesiones inflamatorias de tipo granulomatoso. Se realiza una tinción de Grocott que permite identificar la presencia de hifas en el centro de los granulomas. Se establece, por tanto, un diagnóstico de dermatitis granulomatosa fúngica.

Comment from Veterinary Pathology group in LinedIn:
D.A.: Have you set up fungal cultures from cases like this, and if so, what did you grow?
Our pathologist answer: Unfortunately we did not process any samples for fungal culture.
It is the first time we diagnose this in a chicken, «organic chicken» pathology is an emerging field here, so we cannot give you previous results. However the lesion type is suggestive of a Zygomicoses.
Comment from Livestock Health group in LinkedIn:
O.P.: My experience includes various predisposing factors especially in tropical poultry production ranging from poor husbandry, unfavorable ambient conditions to complicate initial prediposition to the pathogenic fungi organisms. This is a common complication in broiler chickens raised under poorly ventilated pens with wet floor. In addition, there would be infectious foot-pad dermatitis and chronic gangrenous inflammations of the breast tissues
