Sino-oral zygomycosis due to Absidia corymbifera in a patient with acute leukemia.
Fungi belonging to class Zygomycetes become pathogenic in certain predisposing conditions; principally diabetes mellitus, immunosuppression, trauma or burns. We report a case of a 31-year-old man with acute promyelocytic leukemia who developed infection of the sino-oral cavity, due to Absidia corymbifera during a neutropenic phase following induction chemotherapy. A provisional diagnosis of zygomycosis was made by demonstration of broad aseptate branching filamentous hyphae in the scrapings of the palate, which was subsequently confirmed as A. corymbifera by culture. Surgical debridement could not be done due to the thrombocytopenic status of the patient; instead antifungal therapy with amphotericin B was instituted. However, the patient succumbed to the infection after 15 days of its diagnosis. Although infections with Absidia are infrequent, this case highlights the need for its awareness as a potentially lethal opportunistic fungal infection that can present even with short duration of exposure to the usual risk factors.[1]References
