Oral Fusarium infection in a granulocytopenic patient with acute myelogenous leukemia: a case report.

The fungus Fusarium moniliforme causes fusariosis, which can be invasive and fatal in immunocompromised patients. We report a case of oral Fusarium infection in a granulocytopenic patient with acute myelogenous leukemia who developed necrotic ulceration of the gingiva, extending to the alveolar bone, but was otherwise free of any active systemic lesions. Fusarium moniliforme was identified, by histopathology and culture, to be present in the lesion and was deduced to be the causative organism for this invasive oral infection.
