Gastric mucormycosis due to Rhizopus oryzae in a renal transplant recipient

Gastric mucormycosis is a rare disease with a reported fatal outcome of 98%. Manifestations range from colonization of peptic ulcers to infiltrative disease with vascular invasion and dissemination. In our renal transplant patient a deep gastric ulceration infected with Rhizopus oryzae (class Zygomycetes), which is known to be an agent of mucormycosis, was diagnosed in the early posttransplant period after antirejection therapy. The infection was successfully managed with amphotericin B and omeprazole.
