ABSTRACT
Mucormycosis is an emerging and slowly rising fatal infectious disease in most countries. It is the third most common invasive mycosis after candidiasis and aspergillosis. Hematologic malignancies notably acute myeloblastic leukemia (AML) and diabetes mellitus (DM) especially when uncontrolled or there is ketoacidosis are the most common predisposing conditions. Clinical manifestations vary according to the organ involved. Based on anatomic localization, mucormycosis can be classified as one of 6 forms: Rhinocerebral, Pulmonary, Cutaneous, Gastrointestinal, Disseminated and Uncommon presentations. The mortality rate is often very high. Early diagnosis and aggressive treatment are the cornerstone of management. Here we report 5 cases of mucormycosis in patients admitted to Imam Reza hospital, the tertiary referral center in Northwest of Iran. We will also have a brief review of this fungal infection.
