A 6-year-old mixed breed female horse from San Rafael, Alajuela, Costa Rica was treated from bilateral turbid and serous nasal discharge related to an irregular mass in the nasal septum that was partially obstructing the upper respiratory tract. Findings related to the mycological culture, cytology and histopathology determined that Conidiobolus coronatus was the underlying infectious agent. Conidiobolomycosis is a pyogranulomatous subcutaneous disease, without systemic spread, that affects the nasal cavity in horses. After surgical debridement of the mass, the animal was treated with intravenous sodium iodide for several weeks. Three months after the procedure no recurrence of the lesion was detected.
