Mucormycosis (MCM) is a rare fungal infection affecting people with impaired immunity. Data related to MCM from Lebanon are scarce. The aim of this study is to shed light on the epidemiology, incidence, and outcome of patients with MCM hospitalized at a tertiary care center in Lebanon. We conducted a retrospective chart review between Jan 1, 2008 and Jan 10, 2018. All patients with proven or probable MCM were included. A total of 20 patients were included. Their median age was 49 years and the majority were males. Comorbidities included mainly hematologic malignancy and diabetes mellitus. Most common sites of involvement were rhino-orbital and pulmonary, respectively. The number of MCM cases/10.000 hospital admissions increased significantly between 2008 and 2017 (0.47 vs. 1.18; P < 0.05). A liposomal amphotericin B formulation alone or in combination with other antifungals was used as a first line agent in all patients. All-cause mortality was 60%; however, death was attributed to MCM in 20% of cases. The incidence of MCM has significantly increased over the past 10 years at our institution, most likely due to the increasing patient population at risk. Understanding the epidemiology of MCM in our setting would help guide antifungal therapy.
