Core Tip

Core tip: Neutropenic enterocolitis (NE) is a predominantly cecum-based disease with high mortality seen in patients post chemotherapy. The pathogenesis of NE is still poorly understood. The clinical presentation is characterized as ileocolonic inflammation and bowel wall thickening in patients with neutropenia, fever, and abdominal pain. The pathological features of NE include patchy necrosis, hemorrhage, ulcer, edema, perforation, infiltrating organisms, and characteristically, depletion of inflammatory cells (neutrophils). High clinical and histological diagnostic discordance rate exists. High index of clinical suspicion and timely diagnosis are critical for patient appropriate treatment and improvement of survival.
