Rhinophycomycosis.

Rhinophycomycosis, a subcutaneous fungal infection, is less uncommon than many other frequently cited granulomatous lesions of the paranasal sinuses. Four illustrative cases are presented with their characteristic clinical, radiological and histopathological features. The initial origin of the swelling was always in the region of the nasal vestibule and ala. The therapeutic response to potassium iodide, ketaconazole and fluconazole was dramatic and sustained.
