The transition of chronic pancreatic fibroinflammatory disease to neoplasia is a primary example of the paradigm linking inflammation to carcinogenesis. However, the cellular and molecular mediators bridging these entities are not well understood. Because TLR4 ligation can exacerbate pancreatic inflammation, we postulated that TLR4 activation drives pancreatic carcinogenesis. In this study, we ...

INTRODUCTION IgG4-related disease (IgG4-RD) is a fibroinflammatory disorder that may involve almost each organ or system. IgG4-related kidney disease (IgG4-RKD) refers to renal lesions associated with IgG4-RD. The most frequent morphological type of renal lesions is IgG4-related tubulointerstitial nephritis (IgG4-TIN) which is associated with increased IgG4-positive plasma cell infiltration and...

Diabetic fibrous mastopathy is an uncommon self-limiting fibroinflammatory diseae of the breast that is seen predominantly in premenopausal women with long standing type I (insulin dependent) diabetes mellitus. In this report, we present a 29 years old female with uncontrolled diabetes mellitus presenting with bilateral breast masses which were irregular and hypoechoic on ultrasound, gradual en...

Abstract Background IgG4-related disease (IgG4-RD) is an immune-mediated that may present as a tumefactive lesion in nearly any organ. These mass lesions often resemble malignancy both clinically and radiologically, some patients undergo surgical resection which could possibly be avoided with early recognition of IgG4-RD. We performed retrospective single-center study examining how many IgG4-RD...

We aimed to evaluate the clinical and pathologic features of two common medical illnesses and their appropriate workup and pathognomonic findings. A 57-year-old white male presented with a new onset expressive aphasia while traveling abroad. He was evaluated at an outside facility and underwent workup for a stroke. The evaluation included a CT and MRI of the brain demonstrating three new enhanc...
