Small bowel infarction by Aspergillus.

Primary gut involvement by Aspergillus is a rare and often fatal complication of intensive antileukemic therapy. We describe the case of an adult patient affected by acute leukemia who developed a small bowel fungal thromboembolism without radiographic evidence of lung involvement during the post-induction aplastic phase. The diagnosis was made histologically at laparotomy performed for small bowel perforation. The patient died a week later in spite of amphotericin-B treatment and neutrophil recovery. Anti-Aspergillus prophylaxis and early introduction of amphotericin-B in the treatment of febrile neutropenia is probably advisable in all cases of AML.
