A 48-year-old lorry driver presented with 3 weeks of blurred vision, pain and diplopia. There was a right upper lid ptosis with some restriction of eye movements. A CT revealed an enlarged lacrimal gland and lacrimal gland biopsy showed IgG4-positive plasma cells. The patient responded to oral prednisolone and fully recovered. As a condition which mimics a number of diseases, an IgG4-related disease presents a diagnostic challenge and ought to be considered in both acute and chronic presentations.

Intracranial Involvement

IgG4-related disease (IgG4-RD) is a multi-organ chronic inflammatory process caused by infiltration of IgG4-positive plasma cells in one or more organs. Intracranial involvement has only recently become better recognized. Our case series adds to the growing literature on the varying presentations of intracranial IgG4 by describing the clinical and imaging findings of three patients who presented to our institution with intracranial involvement. Our first patient presented with a mass-forming IgG4 pachymeningitis mimicking a sphenoid wing meningioma, which is to our knowledge the largest mass-forming pachymeningitis published in the literature. Our second case depicts another presentation of extensive IgG4 pachymeningitis involving both cavernous sinuses and surrounding Meckel’s caves. The third case describes a patient with presumed lymphocytic hypophysitis, which was later determined to be IgG4-related hypophysitis with concomitant pachymeningitis and perineural spread along the optic nerves. The delayed diagnoses in our cases illustrates the diagnostic challenge that clinicians face in differentiating intracranial IgG4-RD from other infiltrative diseases such as sarcoidosis, granulomatous disease, tuberculosis and lymphoma. Earlier consideration of IgG4-related hypophysitis and hypertrophic pachymeningitis in the differential diagnosis can prevent significant morbidity including unnecessary surgical intervention and organ failure secondary to extensive fibrosis.

Abstract Objective The growing utilization of needle biopsy has challenged the current pathology consensus of IgG4-related disease (IgG4-RD). The aims of this study were to identify the histological characteristics of needle biopsy and surgical specimens and evaluate the ability of needle biopsy in histological diagnosis of IgG4-RD. Methods Biopsies from patients who were referred to as IgG4-RD by the 2019 ACR/EULAR IgG4-RD classification criteria in Peking University People’s Hospital from 2012 to 2019 were re-evaluated. Typical histological features and diagnostic categories were compared between needle biopsy and surgical biopsy. Results In total, 69 patients met the 2019 ACR/EULAR classification criteria and 72 biopsies of them were re-evaluated. All cases showed lymphoplasmacytic infiltrate, while storiform fibrosis and obliterative phlebitis were only present in 35 (48.6%) and 23 (31.9%) specimens, respectively. Storiform fibrosis was more likely to be seen in retroperitoneum lesion (P = 0.033). Surgical biopsy showed significantly higher IgG4+ plasma cells/high-power field (IgG4/HPF) count (P < 0.01) and higher proportion of IgG4/HPF > 10 (P < 0.01). No significant difference was observed with regard to the ratio of IgG4+ plasma cells/IgG+ plasma cells (IgG4/IgG) (P = 0.399), storiform fibrosis (P = 0.739), and obliterative phletibis (P = 0.153). According to the 2011 comprehensive diagnostic criteria, patients who performed a needle biopsy were less likely to be probable IgG4-RD (P = 0.045). Based on the 2011 pathology consensus, needle biopsy was less likely to be diagnosed as IgG4-RD (P < 0.01), especially to be highly suggestive IgG4-RD (P < 0.01). Only 1/18 (5.6%) needle salivary specimens fulfilled the cutoff of IgG4/HPF > 100, which was significantly less than 15/23 (65.2%) of surgical ones (P < 0.01). Conclusions Needle biopsy shows an inferiority in detecting IgG4/HPF count but not in IgG4/IgG ratio, storiform fibrosis, and obliterative phlebitis. Compared with surgical samples, needle biopsy is less likely to obtain a histological diagnosis of IgG4-RD. A different IgG4/HPF threshold for needle biopsy of the salivary glands may be considered.

Abstract Background Fibrous sclerosing tumours and hypertrophic lesions in IgG4-related disease (IgG4-RD) are formed in various organs throughout the body, but disease in the oral region is not included among individual organ manifestations. We report a case of ossifying fibrous epulis that developed from the gingiva, as an instance of IgG4-RD. Case presentation A 60-year-old Japanese man visited the Department of Oral and Maxillofacial Surgery, Gunma University Hospital, with a chief complaint of swelling of the left mandibular gingiva. A 65 mm × 45 mm pedunculated tumour was observed. The bilateral submandibular lymph nodes were enlarged. The intraoperative pathological diagnosis of the enlarged cervical lymph nodes was inflammation. Based on this diagnosis, surgical excision was limited to the intraoral tumour, which was subsequently pathologically diagnosed as ossifying fibrous epulis. Histopathologically, the ossifying fibrous epulis exhibited increased levels of fibroblasts and collagen fibres, as well as infiltration by numerous plasma cells. The IgG4/IgG cell ratio was > 40%. Serologic analysis revealed hyper-IgG4-emia (> 135 mg/dL). The patient met the comprehensive clinical diagnosis criteria and the American College of Rheumatology and European League Against Rheumatism classification criteria for IgG4-RD. Based on these criteria, we diagnosed the ossifying fibrous epulis in our patient as an IgG4-related disease. A pathological diagnosis of IgG4-related lymphadenopathy was established for the cervical lymph nodes. Concomitant clinical findings were consistent with type II IgG4-related lymphadenopathy. Conclusions A routine serological test may be needed in cases with marked fibrous changes (such as epulis) in the oral cavity and plasma cells, accompanied by tumour formation, to determine the possibility of individual-organ manifestations of IgG4-related disease.

Abstract Purpose: To investigate the clinical manifestations of orbital involvement in a large cohort of Chinese patients with IgG4-related disease (IgG4-RD). Methods: A total of 573 patients with IgG4-related disease were included. We described and compared the demographic, clinical, laboratory and histopathologic findings from 314 patients with IgG4-related ophthalmic disease (IgG4-ROD) and 259 with extra-ophthalmic IgG4-RD.Results: Male predominance was found significant in extra-ophthalmic IgG4-RD only. Patients with IgG4-ROD showed younger age at diagnosis and longer duration from onset till diagnosis. In patients with extra-ophthalmic IgG4-RD, the most commonly involved extra-ophthalmic organ was pancreas; while in IgG4-ROD patients, salivary gland was most frequently affected. Multivariate analysis exhibited IgG4-ROD was associated with allergy history, higher serum IgG4/IgG ratio, multiple organs involvement and sialoadenitis. Orbital images were reviewed in 173 (55.1%) IgG4-ROD patients. Fifty-one (29.5%) patients had multiple lesions. Lacrimal gland involvement was detected in 151 (87.3%) patients, followed by extraocular muscles (40, 23.1%), other orbital soft tissue (40, 23.1%) and trigeminal nerve (8, 4.6%). Biopsy was performed from various organs in 390 cases. A dense lymphoplasmacytic infiltration and fibrosis were the main feature in orbital specimens. Storiform fibrosis and obliterative phlebitis were absent in lacrimal gland.Conclusions: Lacrimal gland involvement was the most common orbital manifestation of IgG4-ROD. Patients with IgG4-ROD showed different characteristic in demographic, clinical, laboratory findings compared to patients with extra-ophthalmic IgG4-RD. These features might indicate potential differences in the pathogenesis of these two subgroups of IgG4-RD.

Systemic vasculitis (SV) associated with anti-neutrophilic cytoplasmic antibodies is a multifactorial process characterized by the variability of the epitope specificity of anti-neutrophilic cytoplasmic antibodies and the diversity of clinical phenotypes of the disease. In recent years, there has been an increasing interest in the combination of AAV and the phenomenon of IgG4 hyperproduction, which varies widely within AAV, from anti-neutrophilic cytoplasmic antibodies products of IgG4 subclass of undetermined significance, the presence of IgG4 positive plasma cells in the foci of immunoinflammatory lesions in patients with a definite diagnosis of AAV, to the typical clinical manifestations of an IgG4-related disease (IgG4-RD). We introduce own clinical case and analyze the combined data of the literature, which included 35 cases of a combination of AAV and IgG4-related pathology, indicating existing differences in the clinical manifestations of classical IgG4-RD and when combined with AAV. The currently accumulated data allows us to discuss the allocation of a specific clinical and immunological variant of AAV with IgG4 hyperproduction, characterized by a combination of clinical manifestations of AAV and clinical and / or histological signs of IgG4-related pathology. It is important to emphasize that the allocation of phenotypes of AAV in the future may be important for the personalized choice of treatment tactics for patients.

Systemic Disorder

Immunoglobulin G4–related disease (IgG4-RD) is a systemic disorder characterized by multiorgan fibrosis with IgG4-producing plasma cells, increased IgG4 serum concentration, and responsiveness to steroid therapy. Involvement of the pancreas, salivary glands, orbit, aorta, and other sites has been well documented in the literature; however, there have been limited reports of cases involving the coronary arteries. We report the case of a 53-year-old Hispanic man who was brought to the emergency center and diagnosed with sudden cardiac death. Autopsy was subsequently performed, revealing multiorgan involvement by IgG4-RD, including involvement of the coronary arteries. The inflammation and fibrosis, in combination with concomitant atherosclerotic disease, resulted in severe stenosis of the coronary arteries. Two of the coronary arteries were further occluded by thrombosis. These factors led to cardiac hypoperfusion, myocardial infarction and, ultimately, sudden cardiac death. Fatal involvement of the coronary arteries has not been previously reported, raising a new concern for a severe complication of IgG4-RD.

Eosinophilic Angiocentric Fibrosis

Eosinophilic angiocentric fibrosis is a rare indolent lesion of the head and neck region that has characteristic histologic findings of onionskin fibrosis and prominent eosinophils. Its pathogenesis has been poorly understood and has been most commonly attributed to hypersensitivity or previous trauma. Recently, the lesion has been included in the spectrum of immunoglobulin G4 (IgG4)–related disease. However, few of the existing cases of eosinophilic angiocentric fibrosis have been evaluated for IgG4+ and IgG+ plasma cells. Therefore, we provide an update on the clinical and histologic features of eosinophilic angiocentric fibrosis to increase awareness of the entity and encourage its further characterization as an IgG4-related disease.

Abstract IgG4-related disease (IgG4-RD) is characterized by multi-organ irreversible damage resulting from tissue-specific infiltration of IgG4+ plasma cells and cytotoxic T lymphocytes (CTLs). However, whether IgG4 antibody contributes to the inflammation remains unclear. In this study, we established a mouse model that enabled us to evaluate the pathogenic function of IgG4 antibodies in response to a tissue-specific autoantigen using recombinant ovalbumin (OVA)-specific human IgG4 monoclonal antibody (rOVA-hIgG4 mAb) and the mice expressing OVA of the pancreatic islets (RIP-mOVA mice). We found no inflammatory effect of rOVA-hIgG4 mAb transfer alone; however, co-transfer with OVA-specific CD8 CTLs (OT-I T cells) induced tissue damage with dense lymphocytic inflammation in the pancreas of RIP-mOVA mice. rOVA-hIgG4 mAb caused accumulation of conventional DC1 cells (cDC1s) in the lymphoid tissues, and the dendritic cells (DCs) activated the OT-I T cells via cross-presentation. We also revealed that the synergistic effects of CTLs and antibodies were observed in the other subclasses including endogenous antibodies if they recognized the same antigen. The transfer of OVA-specific CD4 helper T cells (OT-II T cells) into RIP-mOVA mice induced the production of anti-OVA antibody, which had a synergistic effect, through acquisition of a T follicular helper (TFH) phenotype. Moreover, using OT-II T cells deficient in Bcl6 caused lower anti-OVA antibody production and inflammation with OT-I T cells. Our results indicated that autoreactive IgG4 antibodies play an important role of the tissue-specific CTL response in IgG4-RD.
