Current Approach to Neutropenic Enterocolitis Neutropenic enterocolitis (NEC) is a life-threatening clinical condition characterized by fever, abdominal pain, and thickening of the bowel wall. NEC is also known as "typhlitis" because of the involvement of the ileocecal region most often. Nonetheless, it can affect any part of the small or large intestine (1). The pathogenesis is related to reduced host defense mechanism, mucosal damage caused by cancer therapies like high-dose chemotherapy that involve alkylating agents (cyclophosphamide, ifosfamide, busulfan, melphalan, etc.) and antimetabolites (methotrexate, 5-fluorouracil, cytarabine, capecitabine,.etc.), and infiltration of the bowel walls by microorganisms (2-4). Histopathological examination typically reveals bacterial and fungal infiltration, ulcerated mucosal lesions, necrosis, edema, hemorrhage, and thickened bowel wall. Polymicrobial etiology is commonly observed, and include Pseudomonas aeruginosa, Escherichia coli, Klebsiella spp., viridans streptococci, enterococci, Bacteroides spp., and Candida spp. (1, 3).
