A male patient with severe aplastic anemia was admitted for bone marrow transplantation. While waiting for a donor, high doses of methylprednisolone, anabolic steroid and granulocyte colony stimulating factor were given without response. Deferoxamine was administered for prophylaxis of hemochromatosis because of high level of ferritin. Acute right lower abdominal pain and pyrexia developed. A diagnosis of acute appendicitis was made and appendectomy was performed. The histopathological examination of the resected appendix revealed necrotizing hemorrhagic appendicitis with numerous hyphae of Mucorales. Though anti-fungal agent (amphotericin B) administration was continued, he subsequently developed ileo-cecal abscess and eventually died due to myoglobinuric nephropathy caused by extensive necrosis of the iliopsoas muscle. Autopsy revealed dissemination of hyphae of Mucorales in lungs, kidneys, large vessels and muscle of the bilateral lower limbs. Systemic vascular invasion and embolization of fungal hyphae were also observed. However, culture of exudate sampled from ileocecum yielded no Mucorales. It was emphasized that antemortem diagnosis and effective anti-fungal treatments are essential for the management of intestinal mucormycosis. The relation ship between mucormyocosis and deferoxamine was also discussed.

Neutropenic enterocolitis (NE) and acute appendicitis are life-threatening conditions that develop in children with severe or prolonged neutropenia secondary to acute leukemia and lymphoma. The medical records of 118 patients who were treated for acute lymphoblastic leukemia (69 patients), acute myelogenous leukemia (22 patients), or aplastic anemia (27 patients) between 1997 and 2006 in our hospital pediatric hematology department were examined retrospectively. NE was diagnosed in 11 patients (age range, 2.5-16 years) on the basis of clinical and laboratory features. Two of these 11 patients had appendicitis in addition to NE. Conservative treatment was favored for all patients, but 1 patient with acute appendicitis underwent surgery. Neutropenic patients with a hematologic malignancy and abdominal pain should receive their diagnoses immediately and undergo treatment. NE and acute appendicitis should always be considered in the differential diagnosis of abdominal pain. Conservative treatment must be chosen initially for patients with NE, and these patients should be evaluated carefully for surgery. The criteria for the surgical process are the same as those for immunocompetent children. In addition, the close monitoring of hematologic factors is necessary.
