Invasive Colonic Mucormycosis in an Immunocompromised Postliver Transplant Patient.

Mucormycosis (zygomycosis) is an invasive fungal disease caused by Rhizopus species, most commonly implicated in diabetic ketoacidosis and other immunocompromised states. This report presents a unique case of colonic mucormycosis in a patient several weeks after liver transplant. The patient's course was complicated by polymicrobial infection and intra-abdominal abscesses, ultimately leading to septic shock and death. This case is the first of its kind to describe such malignant abdominal mucormycosis in a solid organ transplant recipient.
