VARIOUS fungi are capable of causing primary infection (coccidioidomycosis, histoplasmosis, blastomycosis, and so forth), whereas others usually complicate an underlying disease (aspergillosis, cryptococcosis, and monilia). A relative newcomer to the latter group of fungus infections is mucormycosis, a disease unique in its acute course and highly fatal outcome. Out of 114 cases reported in the world literature,1the majority being discovered post mortem, scarcely over a handful have recovered. Diabetes and leukemia are the 2 main disease states for which mucormycosis has a predilection. However, it has become evident that corticosteroids, antibiotics, and antileukemic agents play a vital role in the invasiveness of the fungus.2Most commonly the disease presents as an infection of the nose, paranasal sinuses, and orbit, with eventual extension into cranial structures. Clinical findings are now considered sufficiently distinctive so that a diagnosis can be made before bacteriologic or tissue confirmation. Such was the
