Several chronic inflammatory diseases have been found to be a subtype of IgG4-related disease, all of which have a typical clinical and histological change, which is based in particular on an overexpression of IgG4 and subsequent fibrosis. At least a part of the retroperitoneal fibrosis, which was originally classified as idiopathic, seems to be assigned to IgG4-related disease. Lymphangiomas are benign, cystic tumors that rarely occur in adults. However, there is no firm association with IgG4-related disease described in the literature to date. This report is about a patient suffering from acute renal failure due to a giant retroperitoneal cyst. Surgical resection remains incomplete in the iliac vessel area due to severe fibrosis and histology revealed features of both lymphangioma and IgG4+ fibrosis. The case description is followed by a brief overview of IgG4-related disease and a consideration of whether lymphangiomas might be assigned to this topic.

Background: Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis disorder that utilizes the RAS-RAF-MEK-ERK pathway. It has a highly variable clinical presentation, where virtually any organ can be involved, thus having the potential of posing a great diagnostic challenge. Over half of the reported cases have the BRAF V600E mutation and have shown a remarkable response to vemurafenib. Case Presentation: We describe herein a patient with a history of stroke-like symptoms and retroperitoneal fibrosis that on initial pathology raised the possibility of IgG4-related disease. However, the patient was refractory to high-dose steroids and progressed further, developing an epicardial soft tissue mass and recurrent neurological symptoms. Integration of the above findings with new information at another hospital about a radiological history of symmetrical lower extremities long bone lesions raised the differential diagnosis of ECD. Molecular analysis of formalin-fixed paraffin-embedded tissue of both of the patient’s retroperitoneal biopsies (the second one of which had shown a small focus of foamy histiocytes, CD68+/CD1a–) was positive for BRAF mutation, confirming the diagnosis of ECD. The patient demonstrated a dramatic and sustained metabolic response to vemurafenib on follow-up positron emission tomography scans. Conclusion: This case highlights the need for developing a high index of suspicion for presentations of retroperitoneal fibrosis that could represent IgG4-related disease but fail to respond to steroids. When unusual multisystem involvement occurs, one should consider a diagnosis of a rare histiocytosis. Vemurafenib appears to be an effective treatment for even advanced cases of both ECD and Langerhans histiocytosis bearing the BRAF V600E mutation.

We describe a 49-year-old woman who presented with continuous bilateral lumbago. As the patient's ultrasonography manifestations were very similar to those of bilateral hydronephrosis, we performed retrograde pyelography and ureteroscopy. However, apart from slight left ureteropelvic junction obstruction, there was no hydronephrosis. Since malignant disease could not be completely denied, computed tomography-guided biopsy was performed. However, the tissue did not show evidence of malignancy. As the patient continued to have lumbago, we measured serum IgG4 levels because of suspicion of retroperitoneal fibrosis secondary to IgG4-related disease, which proved to be high. Further, immunostaining of the renal pelvic biopsy samples showed IgG4-positive cells. Therefore, diagnosing IgG4-related retroperitoneal fibrosis, we administered corticosteroids. The patient responded favorably to the drug, with gradual regression of the lesion.

We report a case of eosinophilic granulomatosis with polyangiitis (EGPA) complicated with a IgG4 related disease like symptoms presenting as eyelid swellings. In the present case, the serum level of IgG4 and the ratio of IgG4 to IgG were generally increased by the disease course of EGPA. Considering the course of clinical symptoms, there is a possibility that orbital manifestations were one of the clinical features during the disease course of EGPA while the histological features of right eyelid tissue and other ocular manifestations were consistent with the diagnosis of IgG4 related disease.
