A case of gastrointestinal zygomycosis in a patient with gastric adenocarcinoma

Zygomycosis, in particular, infection, due to fungi of the order Mucorales, is typically found in patients with diabetes, solid organ transplants, hematologic malignancies, or those treated with deferoxamine. Recently, with increased mylebsuppressive chemotherapy regimens, more cases of pulmonary or disseminated zygomycosis have been reported in neutropenic patients than in the past. We present a white man diagnosed with gastric adenocarcinoma who presented with a small bowel perforation due to gastrointestinal zygomycosis. He was not significantly neutropenic, however, his risk for development of this unusual fungal infection was malnutrition, acidosis, and leukopenia.
