Background: Rhinosporidiosis is considered an endemic disease in some countries and can affect several species of animals, among them, also equines. In this specie, although the nasal cavity is the most common site of infection, in some cases, it could also be spotted in the larynx region. The present study had as an objective to describe two cases of rhinosporidiosis in horses, one of them nasal and the other in the laryngeal area. Cases: Horse 1. A 12-year-old male Standardbred was sent to the veterinary hospital for the resection of the formation presented in the mucocutaneous junction of the left nostril. During the physical exam, a red mass of a moderately consistency, with an irregular, verrucous, pedunculated and ulcerated surface was observed, measuring approximately 2 cm in diameter. The surgical procedure for the resection of the mass was done through the use of the electrocautery technique, with the animal sedated with a romifidine dose of 0.08 mg/kg, a butorphanol dose of 0.04 mg/kg and a local anesthesia of 2% lidocaine. Eight months after the surgical procedure, the animal returned to the hospital and the presence of three new masses was noted in the same nostril, around the region where the extracted mass used to be found and they resembled the previous lesions. The horses owner didnt authorize a new surgery or a new histopathological exam of the lesions. Horse 2. The other case refers to an asymptomatic 15-year-old male mixed breed. During a routine gastroscopic exam, the presence of several reddish coloration nodular and polypoid formations of irregular surface was observed in the larynx. Only one formation in the dorsal portion of the pharynx was observed. During the...(AU)
