This case report describes a 4‐year‐old‐horse with two cutaneous masses on the right crest of the neck. Biopsy revealed chronic nodular pyogranulomatous dermatitis and panniculitis. Giemsa and periodic acid‐Schiff stains showed focal spherical, yeast‐like organisms. A diagnosis of cutaneous fungal granuloma was made. The size of the masses decreased after oral treatment with fluconazole for 10 days combined with potassium iodide for 30 days, and the remaining masses were excised by laser. Lesions did not recur at the site. Fungal granuloma should be considered as a differential diagnosis in horses with cutaneous or subcutaneous nodules. A definitive diagnosis can only be achieved by histopathological examination or by culture of the affected tissue.
