Eosinophilic angiocentric fibrosis.

Eosinophilic angiocentric fibrosis (EAF) is a rare disease of the sinonasal tract, with histologic characteristic features like thick collagen bundles whirling around vessels in a fibrotic stroma with inflammatory cells rich in eosinophils. The Authors present a case of a 31-year-old man with bilateral nasal obstruction with no history of allergies or other systemic disease. The patient underwent a septoplasty with symptoms relieving. An EAF diagnosis was made. Differential diagnosis must rule out other lesions that may mimic EAF such as granuloma faciale, Kimura disease, Wegener granulomatosis, Churg-Strauss syndrome.
