Conidiobolomycosis was diagnosed via culture from an oral lesion in a 1.5-year-old German Shepherd dog. Clinically, the lesion consisted of a large, irregularly shaped, ulcerative focus on the caudal hard palate. Microscopically, the lesion was characterized by an eosinophilic granulomatous stomatitis with hyphal organisms surrounded by eosinophilic sleeves (Splendore-Hoeppli material) suggestive of an entomophthoramycosis. The fungus was cultured and identified with features consistent with Conidiobolus sp. Treatment with itraconazole at 10 mg kg-1 twice daily for 61 days resulted in clinical and radiographic resolution of the lesion.
