Eosinophilic angiocentric fibrosis of the sinonasal tract. Annals of diagnostic pathology [Ann Diagn Pathol] Journal article

Eosinophilic angiocentric fibrosis (EAF) is an uncommon inflammatory fibrosing lesion of the upper respiratory tract and orbit that occurs mainly in young to middle-aged women. The etiology of EAF is unknown. To our knowledge, approximately 28 cases have been previously reported in the English literature. We report here 3 additional cases of EAF of the sinonasal tract; 2 in women aged 19 and 31 years, and 1 in a man aged 49 years. The 19-year-old woman is the youngest patient with EAF ever described. The patients presented with a nasal cavity mass, face pain, or nasal obstructive symptoms of long duration.
