The Primary Brain Eosinophilic Angiocentric Fibrosis, A Rare Case Report

A rare lumpy inflammatory lesion of the orbit: a unique case report

BACKGROUND

Eosinophilic angiocentric fibrosis (EAF) is a rare inflammatory lesion, especially in orbit. EAF is believed to be related to IgG4-related disease (IgG4-RD), but the clinical manifestations of systemic involvement are relatively rare and easy to be confused with tumors or other inflammatory diseases. Histopathological examination is the most important way of its diagnosis and differentiation.

CASE PRESENTATION

We presented a 55-year-old female patient presented with recurrent swelling of the right lower eyelid for more than 2 months. The pathological diagnosis was EAF. Positive immunostaining for IgG, CD34, κ, and λ, while negative immunostaining for IgG4.

CONCLUSIONS

Complete surgical resection is the preferred treatment, histopathological examination is the main diagnostic standard.

Eosinophilic angiocentric fibrosis of the sinonasal tract: a case report and review of the literature

Eosinophilic angiocentric fibrosis (EAF) is a rare chronic benign disorder of unknown etiology and is characterized by submucosal thickening and fibrosis in the upper respiratory tract. In this report, we describe a case of EAF in the nasal cavity of a woman who underwent elective surgery for division of adhesions and has had no recurrence during 2 years of postoperative follow-up. A review of the literature on the clinical manifestations of EAF, sites of lesions, management, and outcomes identified 48 articles that included 72 cases. A summary of these reports is presented, including our present case. The most common anatomic site involved was the nose (77.8%), the most common manifestation was nasal obstruction (66.7%), and the most common treatment modality was surgical resection (83.3%). After surgery, 36% of patients remained free of EAF. The most common pharmacologic agent used was a corticosteroid (38.9%).
