Systemic paracoccidioidomycosis in a patient with enzymatic myeloperoxidase deficiency and acute lymphoblastic leukemia: case report.

Background: Paracoccidioidomycosis is a systemic fungal infection that is potentially fatal, and the most prevalent of its kind in Latin America. The predisposition to infection appears to be related to abnormalities in cellular immunity, given its low prevalence in endemic regions. The role of myeloperoxidase deficiency has not been elucidated.
