Sinus infection caused by exserohilum rostratum in a pediatric patient with acute myeloid leukemia

Abstract

The episodes of febrile neutropenia are severe cases that require an exhaustive etiological study and a quick start of antimicrobial agents. Within the possible microorganisms, fungal origins are also found, and depending on its tissue invasion, they can reach a high mortality rate. A case of a pediatric patient who suffered from acute myeloid leukemia is reported, and after his induction chemotherapy, the patient showed an episode of febrile neutropenia, which matches a rhinosinusal infection caused by Exserohilum rostratum, a filamen-tous fungi that is uncommonly associated with pathological cases. An antifungal therapy and an early surgical treatment were started, which lead to a positive response, without complications to the patient. After the monitoring and receiving secondary prophylaxis during the episodes of neutropenia, the patient hasn’t presented new injuries nor rhinosinusal damage.
