Pathol Int 2022; 72:361-370.

Abstract
Immunoglobulin G4 (IgG4)-positive marginal zone lymphoma (MZL) is rare and undefined. It is unclear whether IgG4-positive MZLs have as favorable an outcome as MZLs in general. Also, correlation with IgG4-related disease (IgG4-RD) and IgG4-positive MZLs is unknown. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews, we searched MEDLINE and EMBASE for all peer-reviewed articles using keywords including"IgG4" and "marginal zone lymphoma" from their inception to February 20, 2022. Twenty-two articles, including six observational studies and 24 cases from 16 case reports and case series, were included. Only one study had a comparative group, and the other five were exploratory observational studies. IgG4-positive MZLs commonly occurred in males (83.3%). It primarily involved ocular adnexa (41.7%) and skin (29.2%). Only 29.2% had concurrent IgG4-RD, and no expiration was noted. While most cases were treated with excision, resection, or clinical observation, 21.7% received rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone as a first-line treatment. This systematic review summarizes the current understanding of the characteristics of IgG4-positive MZLs. While there seems to be IgG4-RD-related and de novo IgG4-positive MZLs, future research needs to clearly define MZL with polyclonal IgG4-positive cells and IgG4-producing lymphoma. Further studies are critical to clarifying long-term prognosis and optimal surveillance planning.

Abstract
BACKGROUND Idiopathic retroperitoneal fibrosis (iRPF) is a rare fibro-inflammatory disease, characterized by inflammation of the abdominal aorta and its surrounding structures. The exact pathophysiology remains unclear. Diagnosis is often troublesome due to the non-specific and highly variable clinical presentation. Standardized treatment protocols are lacking. OBJECTIVE This article presents a review on iRPF, addressing clinical and diagnostic modalities as well as its pathophysiology and the possible inclusion within the IgG4-related disease (IgG4-RD) spectrum. Finally, a diagnostic-therapeutic algorithm for a standardized approach to iRPF is proposed. METHODS The PubMed Internet database was searched. Articles were selected based on the relevance of abstract, article type and impact of the journal. RESULTS iRPF and IgG4-RD share a common autoimmune aetiology. Diagnostics are multimodal and based on imaging. Ruling out malignancy should be of primary concern. Complications are mostly of renal or vascular origin due to compression of retroperitoneal structures. Corticosteroids remain the first-line treatment regimen and are mostly successful, but evidence supporting alternative immunosuppressive and anti-inflammatory treatments is growing. Long-term therapy, as well as follow-up, is paramount in this chronic and often relapsing disease.

The value of 18F-FDG PET/CT in the distinction between retroperitoneal fibrosis and its malignant mimics. Semin Arthritis Rheum 2017; 47:593-600.

Abstract
OBJECTIVE To discuss the utility of 18F-fluorodeoxyglucose (FDG) positron emission tomography/computerized tomography (PET/CT) in the diagnosis of idiopathic retroperitoneal fibrosis (iRPF). METHODS IRPF patients diagnosed between September 2011 and June 2016 were included. Retroperitoneal malignancy patients were included as control. The morphological features and FDG uptake of retroperitoneal lesions were measured along with lymph node (LN) mapping. RESULTS Seventy-one iRPF patients were included. Fifteen lymphoma patients and 6 retroperitoneal metastatic malignancy patients were included as control. Significant differences in morphological features were observed between iRPF and lymphoma but not retroperitoneal metastatic carcinoma. Compared with malignancy, iRPF displayed a lower frequency of high-FDG-uptake retroperitoneal lesions (P = 0.017) and a lower mean maximum standardized uptake value (SUVmax) (P < 0.001). LNs located at axillary, retroperitoneal, supraclavicular, inguinal or peritoneal sites were more frequently observed in retroperitoneal malignancy, therefore, were defined as specific LNs. The area under the curve (AUC) for SUVmax was 0.893 with a sensitivity of 85.7% and a specificity of 80.3%, when the cut-off value of the SUVmax was 6.23. The AUC for the logistic regression model combining the lesions above renal arteries, the SUVmax and the number of specific LNs was 0.987 with a sensitivity of 90.5% and a specificity of 98.6%. The risk stratification model analysis indicated that most of the retroperitoneal malignancy patients were at moderate or high level, while most of the iRPF patients were at low risk. CONCLUSIONS Retroperitoneal malignancy can mimic iRPF morphologically. 18F-FDG PET/CT can help to distinguish iRPF from retroperitoneal lymphoma and metastatic malignancy.

Abstract
Retroperitoneal fibrosis (RPF) is a rare disease characterised by fibrous tissue proliferation in the retroperitoneum, with encasement of the ureters and large vessels of the abdomen as the most destructive of potentially severe complications. It can either be idiopathic, or secondary to infections, malignancies, or the use of certain drugs. The idiopathic form accounts for approximately 75% of the cases, and is usually responsive to immunosuppressive therapy. In recent years, the emergence of a new clinical entity, IgG4-related disease (IgG4-RD), shed light on many fibro-inflammatory disorders once thought to be separate clinical entities, although frequently associated in the so-called multifocal fibrosclerosis. Among these, together with sclerosing pancreatitis and cholangitis, pseudotumour of the orbit, idiopathic mediastinal fibrosis and other conditions, is idiopathic retroperitoneal fibrosis (IRF). Both IRF and IgG4-RD can be associated with a wide variety of disorders, usually governed by immune-mediated (and particularly auto-immune) mechanisms. In our review, we discuss the clinical and therapeutic challenges IRF presents to the internist, as well as the meaning of its recent inclusion in the IgG4-RD spectrum from a clinical practice standpoint.
