Abstract
Mucormycosis is an uncommon but severe fungal infection, typically observed in immunocompromized patients. We report a case of acute lymphoblastic leukemia complicated by rhino-oculo-cerebral mucormycosis in a pediatric patient. Combination lipid polyene-echinocandin therapy, along with surgical debridement appeared to be effective. Nevertheless, a severe relapse occurred during posaconazole prophylaxis; antifungal therapy, hemimaxillectomy and suspension of chemotherapy were performed. Although mucormycosis is a frequently lethal infection, prompt diagnosis and aggressive treatment can be successful even in cases of relapse.
