title: Benign Mucor colonization (fungus ball) associated with chronic sinusitis.
abstract: Mucormycosis of the nasal cavity and paranasal sinuses is an aggressive, life-threatening condition characterized by fulminant destruction of soft tissues and bone, vascular invasion, and thrombosis. Patients who have this infection generally are immunosuppressed or diabetic. The most effective treatment is immediate surgical debridement of all involved tissue, along with systemic antifungal agents. We identified four patients with chronic sinusitis in whom Mucor organisms were histologically confirmed within the sinus contents but not in the sinus mucosa. All four were successfully treated with conservative debridement. Our dilemma was determining appropriate treatment for this apparently less aggressive condition. We conclude that conservative debridement is the treatment of choice in the absence of tissue invasion, and that systemic antifungal therapy is probably unnecessary.
