Chronic rhinocerebral phycomycosis in association with diabetes.

Two patients with rhinocerebral phycomycosis associated with diabetes are presented. The chronic nature of the illness in these two cases in emphasized in contrast to the more fulminant course of most previously reported patients. A high index of suspicion is needed to establish the diagnosis as rapidly as possible. Treatment of the underlying disease combined with amphotericin B therapy and radical surgical excision of all infected tissue is important to establish cure of these patients.
