A surgical case of eosinophilic angiocentric fibrosis of the lung

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%).

Eosinophilic angiocentric fibrosis and IgG4-related disease revisited

INTRODUCTION

Eosinophilic angiocentric fibrosis (EAF) has been postulated to lie on the spectrum of IgG4-related disease (IgG4-RD) in a study reported in 2011. However, the aetiology of EAF remains controversial despite increasing literature reporting IgG4-RD targeted investigations in those studies. This review aims to formally evaluate the relationship between EAF and IgG4-RD using the latest 2019 ACR/EULAR classification scheme for IgG4-RD.

METHODS

A literature search was performed on the PubMed database for all studies describing patients diagnosed with EAF. Additionally, two EAF cases were retrospectively identified from our institution and presented. The demographics, clinical presentation, histological and serological data of each patient were analysed.

RESULTS

A total of twenty cases were evaluated, including eighteen patients from fourteen articles in the English literature and two cases from our institution. Six out of twenty (30%) patients with EAF met the criteria for IgG4-RD with the 2019 ACR/EULAR classification scheme.

CONCLUSION

This represents the first attempt at formally evaluating the relationship between EAF and IgG4-RD using a validated set of classification criteria. Using the currently available data, a small proportion of patients with EAF met the criteria for IgG4-RD. However, various limitations of this study suggest that further efforts at disease characterization of EAF may be required.
