INTRODUCTION

Eosinophilic angiocentric fibrosis (EAF) is a rare benign fibrotic lesion of unknown aetiology, found predominantly in the upper respiratory tract where it causes obstruction1. The first case of this lesion was described by Holmes and Panje in 1983 who named it intranasal granuloma faciale2. In 1985, Roberts and McCann described three cases of lesions in the upper respiratory tract as mucous variants of granuloma faciale. Based on detailed histology, the authors recommended the name eosinophilic angiocentric fibrosis1. Additional cases of this disease have been published3–20. We present a case of a patient with this diagnosis.

CASE REPORT

A 49-year-old male patient observed deformation of his nose gradually worsening for 20 years. In the last five years the patient observed a gradually increasing nasal obstruction, more apparent on the left. The patient suffered an unspecified nose injury in his childhood and had a history of allergies to dust and pollen. He had a surgery of the nasal septum five years ago. The patient had no other history of problems. Examination showed septal perforation and septal thickening in its frontal part. Spherical, elastic resistance was felt in this area of the septum and nasal pathways, which deformed the external nose, particularly on the left. There were no cutaneous lesions. Computed tomography (CT) showed a soft-tissue, expansive lesion in the frontal part of the nasal cavity, sized 41 x 31 mm. Partial destruction of nasal bones was apparent, more distinct on the left (Figure 1).

Biopsy of the lesion showed evidence of chronic inflammatory changes. We performed removal of the tumour from lateral rhinotomy including resection of parts of the nasal bones and lateral nasal cartilages on both sides. Furthermore, we performed partial resection of the frontal process of the maxilla on the left. The lesion caused partial destruction of lateral nasal cartilages on both sides of the nose. At the same time, we performed partial resection of the cartilaginous and bony part of the septum. Subsequently, corticosteroids were administered locally for three months.

Histology examination revealed dense collagenous sclerosing lesion with obliterative and concentric perivascular fibrosis and inflammatory infiltrate with significant numbers of eosinophils. Histologically the lesion can be separated into early and late phases: The early phase consists of eosinophilic vasculitis without fibrinoid necrosis, occurring in a patchy fashion and involving groups of capillaries and/or venules. Eosinophils create a cluster and migrate through the vessel wall and are accompanied by a mixture of plasma cells, lymphocytes, and fibroblasts (Figure 2a). The late lesion is characterized by a dense fibrous thickening of stroma and a characteristic obliterative perivascular onion skin whorling of collagen fibres and reticulin. The inflammatory infiltrate becomes progressively hypocellular with increasing fibrosis (Figure 2b). The typical histological findings with both early and late phases of the disease, which could both be seen in a single biopsy, were noted in our patient.

Two years later, a lesion recurrence was observed in the left lower edge of the orbit, in its medial part. Extirpation of the lesion was performed. We also reconstructed the saddle-like deformation of the nose after the previous surgery by inserting an alloplastic implant (Medpor). We used this implant for augmentation of the nasal dorsum and as a tip support. The application of the Medpor implant for facial reconstruction was described for example by Niechajev21. The patient was free of any problems thereafter. Five years later, a lesion recurrence was observed in the lateral part of the nose on the right and in the frontal part of the septum. The recurrence was not in contact with the implant. The lesion was gradually removed from lateral rhinotomy on the right, including expanded resection of a part of the nasal bone on the right, partial resection of the frontal process of the maxilla and of the affected part of the septum. No recurrence of the lesion was observed at regular follow-up visits in the course of subsequent two years. Reconstruction of the nose by Medpor implant was successful in restoring aesthetics and function.

DISCUSSION

The PubMed database was searched using the following keywords: eosinophilic angioncetric fibrosis, nasal cavity, nasal obstruction. Articles published in English from 1983 to 2015. We have selected only a few main articles for this publication.

EAF is a slowly progressing fibrotic lesion3–7. The aetiology is unknown.

Associations with trauma, allergy and nasal surgery are reported in the literature7,8. Fang et al. (2014) published review of 52 cases with sinonasal EAF8.

Typical symptoms of the disease include nasal obstruction, epistaxis, pain and swelling6,8. As shown by research studies, EAF is a part of the spectrum of IgG4-related systemic diseases9.

Non-enhanced CT revealed the lesion to be of homogenous isodensity compared with grey matter and rarely has calcifications. As the lesion progresses, it may cause adjacent bone remodelling, thinning, slight absorption or even sclerosis. EAF is generally isointense relative to grey matter on Tl-weighted images, with moderate inhomogeneous enhancement after contrast administration. Most lesions exhibit hypointense signal intensity on T2-weighted images in comparison to fibrosis seen in the late stage lesions10. In our case, CT showed clear destruction of nasal bones particularly on the left including partial destruction of the frontal process of the maxilla on the left.

The histological features were described by Roberts and McCann in 19851. The histology shows gradual progression of the lesion from an early inflammatory lesion to a fibrotic lesion. Both features may be found in a single biopsy. The early lesion is characterized by the presence of eosinophilic vasculitis without fibrinoid necrosis, occurring in a patchy fashion involving groups of capillaries and/or venules in the submucosa. The eosinophils cluster around and migrate through the vessel wall, show degranulation and are accompanied by a variable number of plasma cells and lymphocytes in the perivascular space. There is no true granulomatous reaction. The late lesion is characterised by obliterative perivascular onionskin whorling of collagen fibres and reticulin. The inflammatory infiltrate becomes progressively scanty as fibrosis increases1. The typical histological findings with both early and late phases of the disease, which can both be seen in a single biopsy, were noted in our patient.

Granuloma faciale, Wegener‘s granulomatosis, Churg-Strauss syndrome, Kimura‘s disease3,5,9,11–13, angiolymphoid hyperplasia with eosinophilia3,5, and nasal NK/T-cell lymphoma10,14 should be considered in the differential diagnosis.

The treatment of EAF is predominantly surgical; corticosteroids provide no improvement3–5,10–13,15,16, while the same applies to antibiotics3,11,12,16 and immunosuppressants5. Recurrences of the disease are often observed3,10,13. Our patient had repeated resections of the lesion for its recurrences. As shown in literature, radical resection is crucial for the treatment of EAF. This procedure may be difficult at times given the extent and localization of the disease7.

CONCLUSION

EAF is a rare benign lesion of unknown aetiology, found predominantly in the upper respiratory tract. Fibrosis must be confirmed by considering other lesions in the differential diagnosis. The typical histological finding provides the basis for determining the correct diagnosis. CT and magnetic resonance imaging combined with history may contribute to making the right diagnosis and also provide closer specification of the extent of the lesion. The most common treatment method is surgical resection. The published case is unique in our country.
