[Mucormycosis--a rare complication in patients with diabetes mellitus].

Mucormycosis usually occurs in immunocompromised patients or in patients with diabetes mellitus. Pathogens are moulds of the mucorales species. The diagnosis is made by histological examination of biopsies. A 39 year-old patient with insulin-dependent diabetes mellitus was admitted with a tentative diagnosis of a tumour of the maxilla. After diagnosis of hyphae of the mucorales species, the patient's diabetes was stabilised and he was treated over 17 weeks with amphotericin B (40 mg per day) and made a good recovery. A 58 year-old insulin-dependent patient with ethmoidali and sphenoidali sinusitis did not respond to antibiotic therapy. Mucormycosis was diagnosed by means of biopsy. Although treatment with amphotericin B was started, the patient died after 3 weeks due to multiple organ failure.
