Eosinophilic angiocentric fibrosis: an unusual entity of the sinonasal tract.
We present the case of a 45-year-old man who presented with medication-resistant chronic bilateral nasal obstruction. The patient had no known history of allergy or any other disease. Nasal septoplasty was performed to relieve his symptoms. Histologically, thick collagen bundles were seen, characteristically whorling around vessels in a fibrotic stroma. Inflammatory cells, rich in eosinophils, were scattered throughout the lesion. No granulomas, necrosis, or vessel destruction were present. A diagnosis of eosinophilic angiocentric fibrosis was made. This neoplasm, which has very characteristic histologic features, is a rare entity of the sinonasal tract.
