Zygomycosis (mucormycosis) is a rare, highly aggressive opportunistic fungal disease caused by saprophytic fungi, belonging to the division Zygomycota, class Zygomycetes. Patients with immunodeficiency, neutropenia, iron overload, hematological malignancies, as well as diabetics with ketoacidosis are typically affected.
Case presentation: Authors describe the case of an eighteen-year old man with poor compliance suffering from diabetes since the age of nine. He was admitted with ketoacidotic somnolence in severe general condition with unilateral periorbital erythematous edema. Though from nasal exudates gained by the fibero-endoscopic sinus surgery Methicillin-resistant Staphylococcus aureus and Pseudomas aeruginosa was cultured, amphotericin-B was administered as the medical history, clinical picture suggested presence of zygomycosis. An invasive infection caused by Rhizopus oryzae was confirmed by histology and microbiology.
Discussion: The combination of antifungal therapy, repeated surgical interventions and granulocyte colony-stimulating factor resulted in good clinical response. Four month after discharge he is alive and doing well.
