A 9-year-old horse presented serosanguineous nasal discharge, absence of breath out through the right nostril, and respiratory noise. Endoscopic and radiographic exams revealed a six centimeter diameter mass, covered by yellowish mucosa, which was obstructing the entire right nasal cavity and part of the left one. The mass was excised through a right frontal sinusotomy. The microscopic exam and the culture revealed a fungic granulomatous rhinitis. Antibiotic and anti-inflammatory drugs were postoperatively administered; moreover, camomile tea and distilled water were flushed in a drain placed above the bone flap.
