Ocular adnexal extranodal marginal zone lymphoma (OA-EMZL) and immunoglobulin G4-related ophthalmic disease (IgG4-ROD) may exist on a continuum. Presence of immunoglobulin light-chain restriction and clonal gene rearrangement suggests presence of lymphoma; whereas bilateral, infraorbital nerve and systemic involvement accompanied by elevated serum IgG4 levels may indicate synchronous IgG4-ROD. Although steroids have been the mainstay for the treatment of IgG4-ROD, radiotherapy (RT) has been used occasionally. The reported RT doses range between 24 and 30 Gy, which can result in acute and late toxicities. A low-dose regimen of four Gy has not been previously described. We describe a patient with bilateral OA-EMZL arising from IgG4-ROD successfully treated with low dose ‘boom-boom’ radiotherapy. In addition, we review the literature for the association between these two conditions and the role of RT in their management.

ObjectiveMeningeal involvement in Immunoglobulin G (IgG)-4-related disease is rare and only described in case reports and series. Because a review into the disease is lacking, we present 2 cases followed by a literature review of IgG4-related hypertrophic pachymeningitis (IgG4-HP).MethodsTwo IgG4-HP cases were reported, one involving the spinal cord and responding to surgical management and a second involving the brain and responding to Rituximab therapy. We then review clinical cases and case-series of histologically proven IgG4-HP that were published in the PubMed-NCBI database.ResultsForty-two case reports and 5 case-series were studied (60 patients, 20 women). The median age was 53. Eighteen patients had systemic involvement and 24 had single-organ IgG4-HP. Fifty-five percent of patients had an elevated serum IgG4. Treatment was surgical in 20/53 cases. Steroid therapy and immunosuppressors were effective in 85% and more than 90% of the cases, respectively. The rate of disease relapse was 42.1% after steroid therapy was discontinued.Discussion/conclusionIgG4-HP is characterized by the lack of extra-neurologic organ-involvement and systemic signs. Histopathologic studies should be performed as it is crucial for diagnosis because serum markers are rarely informative. 18F-FDG positon tomography can be useful to characterize systemic forms. There is no specific CSF marker for IgG4-HP and the diagnostic value of CSF IgG4 levels needs to be studied with larger samples. We provide a treatment algorithm for IgG4-HP. Such treatment strategies rely on early surgery, steroids, and early immunosuppressive therapy to prevent neurologic complications.

Abstract Purpose: Clinical phenotypes in Immunoglobulin G4-related disease (IgG4-RD) according to the affected organs affected have different risks of malignancies. We attempt to determine the association of malignances with IgG4-related ophthalmic disease (IgG4-ROD). Design: Retrospective cohort study. Methods: Review of medical records, orbital images and histopathology reports in a territory-wide cohort of patients fulfilling the “probable” or “definite” comprehensive diagnostic criteria of IgG4-RD from 2005-2019. Findings: Among 122 patients who had biopsies taken from adnexal lesions including lacrimal glands (n=108), orbital mass (n=30), infiltrated orbital fat (n=10), conjunctiva (n=2) or extraocular muscles (n=3), 16 (13%) developed malignancies over 73±48months’ follow-up. There were 9 cases of ocular adnexal lymphoma (OAL) and 7 extra-orbital malignancies. Compared with the general population, the incidence of OAL was significantly higher (standardized incidence ratios, SIRs=10.0, 95%CI=4.5-17.6) while that of extraorbital malignancy was similar. The SIR was highest within the first year (SIR=46.7, 95%CI=18.5-87.6) when 7 OAL were concomitantly diagnosed. Patients who developed OAL or extra-orbital malignancies were older than other patients when diagnosed of IgG4-ROD (64.9±7.1, 68.3±8.5 versus 55.2±15.0 years, p<0.05). Asymmetric lacrimal gland enlargement (78% versus 13%), lack of frontal (0% versus 12%) or infraorbital nerve enlargement (0% versus 36%)were associated with OAL (all p<0.05). Pre-treatment serum IgG4 level or pattern of extraorbital involvement was similar among patients with or without malignancies. Conclusion: In this biopsy-proven IgG4-ROD cohort, 7% developed OAL which was 10 times higher than the general population. Patients with asymmetric lacrimal gland enlargement or without trigeminal nerves involvement radiologically were associated with OAL.

PurposeTo investigate the factors associated with response to steroid treatment and recurrence in patients with IgG4-related ophthalmic disease (ROD).MethodsTwenty-eight patients with biopsy-proven IgG4-ROD treated between March 2010 and January 2017 were included in this retrospective study. Clinical features, serum IgG4 levels, systemic involvement, treatments and treatment outcome, factors associated with response to treatment and recurrence were assessed.ResultThirteen men and 15 women (mean age 50.8 years) were evaluated over mean follow-up period of 27.3 months. Elevated serum IgG4 levels (>1.35 g/L) and systemic disease were noted in 9 (32%) and 18 patients (64%), respectively. The lacrimal gland was involved in all patients, and 22 patients (78.6%) had bilateral involvement. Most patients (82%) responded well to systemic steroids, but 12 (43%) relapsed after the initial steroid treatment, requiring additional therapies to achieve remission. Complete response to initial steroid treatment was associated with elevated serum IgG4 levels before treatment (P=0.001) and bilateral orbital involvement (P=0.050). Recurrence was associated with elevated serum IgG4 levels before treatment (P=0.007), lower dose (P=0.057) and shorter duration of initial steroids (P=0.042). Patients with recurrence eventually required significantly more steroids than those without recurrence (P=0.011).ConclusionsPatients with IgG4-ROD responded well to systemic steroid treatment, but recurrence was common, particularly among those with elevated serum IgG4 levels and shorter duration of initial steroid treatment. Low-dose maintenance treatment with systemic steroids should be considered to avoid recurrence in patients with elevated serum IgG4 levels.

Immunoglobulin G4 related disease (IgG4-RD) is a systemic fibro inflammatory condition that usually presents with multiorgan involvement. We present a rare case of 54 year old male with an isolated IgG4-RD of epididymis. The patient presented with a progressive swelling of the left testicle. A clinical diagnosis of tuberculosis was made. Ultrasound scrotum showed a relatively hetero-echoic mass lesion involving the left epididymis in close proximity to the left testis. There was a focal spindle cell proliferation and an increase in number of plasma cells and keloid like collagen. Immunohistochemistry was positive for vimentin and IgG4 and negative for CD34. Serum level of IgG4 was elevated (165 mg per dL). Computed tomography of abdomen and thorax did not show any systemic involvement. HE was posted for excision of the epididymal mass. Intraoperatively, the mass was found to be densely adherent to left testicle and inseparable from it, necessitating left total orchiectomy. Histopathology and immunohistochemistry with elevated serum IgG4 levels confirmed the diagnosis of IgG4-RD of the epididymis. To the best of our knowledge, this condition is an extremely rare entity, with only very few cases of isolated IgG4-RD of epididymis reported in medical literature, with no other systemic manifestations.

Background: Benign immunoglobulin G4 (IgG4)-related orbital disease (IgG4-ROD)—characterized as tumors mimicking malignant orbital lymphoma (OL)—responds well to steroids, instead of chemotherapy, radiotherapy and/or surgery of OL. The objective of this study was to report the differences in computed tomography (CT) features and- serum IgG4 levels of IgG4-ROD and OL. Methods: This study retrieved records for patients with OL and IgG4-ROD from a pathology database during an eight-year-and-five-month period. We assessed the differences between 16 OL patients with 27 lesions and nine IgG4-ROD patients with 20 lesions according to prebiopsy CT features of lesions and prebiopsy serum IgG4 levels and immunoglobulin G (IgG) levels This study also established the receiver-operating curves (ROC) of precontrast and postcontrast CT Hounsfield unit scales (CTHU), serum IgG4 levels, serum IgG levels and their ratios. Results: Significantly related to IgG4-ROD (all p < 0.05) were the presence of lesions with regular borders, presence of multiple lesions—involving both lacrimal glands on CT scans—higher median values of postcontrast CTHU, postcontrast CTHU/precontrast CTHU ratios, serum IgG4 levels and serum IgG4/IgG level ratios. Compared to postcontrast CTHU, serum IgG4 levels had a larger area under the ROC curve (0.847 [95% confidence interval (CI): 0.674–1.000, p = 0.005] vs. 0.766 [95% CI: 0.615–0.917, p = 0.002]), higher sensitivity (0.889 [95% CI: 0.518–0.997] vs. 0.75 [95% CI: 0.509–0.913]), higher specificity (0.813 [95% CI: 0.544–0.960] vs. 0.778 [95% CI: 0.578–0.914]) and a higher cutoff value (≥132.5 mg/dL [milligrams per deciliter] vs. ≥89.5). Conclusions: IgG4-ROD showed distinct CT features and elevated serum IgG4 (≥132.5 mg/dL), which could help distinguish IgG4-ROD from OL.

Abstract Background Immunoglobulin G4 (IgG4)-related disease (IgG4-RD) is an immune-mediated fibroinflammatory condition with high serum IgG4 levels affecting various organs, such as the pancreas, lacrimal and salivary glands, thyroid, kidney, and lung. Typical cardiovascular manifestations of IgG4-RD include periaortitis, coronary arteritis, and pericarditis. However, reports of IgG4-RD associated with coronary arteritis are rare. Here, we report a case of IgG4-related masses surrounding the coronary arteries. Case summary A 59-year-old man was referred to our hospital because of mediastinal masses detected by computed tomography (CT). Coronary CT angiography revealed masses surrounding the right coronary artery and the left anterior descending coronary artery. An elevated serum level of IgG4 and histological findings led to the diagnosis of IgG4-related coronary arteritis with mass formation. Coronary angiography showed numerous feeding arteries to the masses, which were demonstrated as multiple microchannels in the intravascular ultrasound (IVUS) images. Discussion IgG4-RD involving the cardiovascular system has been reported. However, coronary artery disease associated with IgG4-RD is very rare, and the mechanism of mass formation in IgG4-related coronary arteritis is unclear. In our case, within the cardiovascular system, IgG4-RD was limited to the coronary arteries, suggesting that the affected coronary arteries may provide the necessary blood supply to the mass, thus, aiding its growth. These findings were supported by the images from coronary angiography and IVUS.

Immunoglobulin G4 (IgG4)-related disease is a multi-organ, immune-mediated, fibro-inflammatory disorder characterized by tumefactive masses in the affected organs. Incidence and prevalence of IgG4-related disease (RD) are not clearly known and have slight male preponderance. It often involves multiple organs at the time of presentation or over the course of disease mimicking malignancy, Sjogren's syndrome, antineutrophil cytoplasmic antibodies associated vasculitis, infections. A thorough workup is needed to rule out these mimickers. A 33-year-old gentleman presented to us with history of progressive swelling in the right peri-orbital region for four years. On evaluation, abdominal imaging was notable for the sausage-shaped pancreas and hypoenchancing nodules in bilateral kidneys. Histological examination of right lacrimal gland revealed lymphoplasmacytic infiltrate and storiform fibrosis. Serum IgG4 levels were normal, and immunostaining was negative. A diagnosis of IgG4-RD was suggested because of multi-organ involvement, classical radiological and histopathological features. Awareness about IgG4-RD, an under-recognized entity is essential, as it is treatable, and early recognition may help in a favourable outcome. Appropriate use of clinicopathological, serological and imaging features in the right clinical context may help in accurate diagnosis. Elevated serum IgG4 levels and biopsy are not mandatory for the diagnosis.

Autoimmune pancreatitis (AP) is a rare autoimmune pancreatic manifestation of systemic immunoglobulin G4 (IgG4)-related sclerosing disease. Distinguishing between AP and pancreatic cancer is crucial because the clinical courses, treatments, and prognoses of these two disease entities are quite different. We herein report a case involving a 52-year-old man with subacute epigastralgia who visited our hospital for evaluation of a suspicious pancreatic mass found during esophagogastroduodenoscopy. Enhanced computed tomography (CT) revealed an enlarged lesion in the pancreatic head with encasement of hepatic vessels. The lesion also exhibited increased 18F-fluorodeoxyglucose accumulation on positron emission tomography/CT imaging, which was highly suggestive of pancreatic cancer. After open biopsy, morphologic examination showed an inflammatory infiltrate in the pancreas, which was compatible with chronic sclerotic pancreatitis. Further laboratory tests revealed an elevated serum IgG4 level, and the diagnosis of sclerotic pancreatitis was then confirmed. After corticosteroid treatment, the pancreatic lesion showed shrinkage on follow-up CT, and the serum IgG4 titer decreased to the normal range. This case suggests that clinicians should be familiar with the clinical presentations and diagnostic criteria of AP versus pancreatic cancer. An awareness of the differences between these diseases may avoid misdiagnosis and unnecessary surgical intervention.

Immunoglobulin G4 (IgG4)-related disease (IgG4-RD) is a novel clinical disease that is characterized by elevated serum IgG4 concentrations and tumefaction or tissue infiltrated by IgG4+ plasma cells. The clinical manifestations of IgG4-RD depend on the type of tissues affected. IgG4-related sclerosing cholangitis is a type of IgG4-RD. We report a patient who initially visited a local hospital with a 5-month history of jaundice. He was found to have a mass in the upper part of the common bile duct that mimicked cholangiocarcinoma. He underwent surgery in our hospital and was later diagnosed with IgG4-related sclerosing cholangitis. We administered prednisolone 40 mg once a day for treatment. Taking into account the possible side effects of moderate-dose hormone therapy, we also administered teprenone, potassium chloride, and calcium carbonate. The patient did not have any recurrence of symptoms or adverse drug reactions during follow-up.

Immunoglobulin G4 related disease (IgG4-RD) is a recently perceived fibroinflammatory condition, identified as a systemic illness for the first time in the early 2000. It can involve virtually every organ of the body, commonly presenting as lymphadenopathy, retroperitoneal fibrosis, autoimmune pancreatitis, tubulointerstitial nephritis, parotid or lacrimal gland enlargement. The diagnosis is confirmed by histopathological analysis and is often, but not always accompanied by an increased level of serum IgG4 concentration. In fact, the name addressing this autoimmune fibroinflammatory condition may be considered a misnomer, as the role of the non-inflammatory immunoglobulin IgG4 in the immune mechanism of IgG4-RD remains to be elucidated.
