Abstract
Fusarium is a ubiquitous fungal species found in soil and water. While fusarium can cause localized infection in healthy individuals, it most commonly affects those with compromised immune systems, particularly those with prolonged neutropenia. The morality rate of systemic infection approaches one-hundred percent. Here we present two cases of disseminated fusarium infection in two patients with acute lymphoblastic leukemia (ALL) along with review of literatures regarding prophylaxis and treatment.
