A specimen of a venous channel (Panel E, hematoxylin and eosin) is characterized by total obliteration (i.e., obliterative phlebitis). Arrowheads mark the periphery of the vein. A high-power image ...

The critical histopathological features are a dense lymphoplasmacytic infiltrate, a storiform pattern of fibrosis, and obliterative phlebitis. We propose a terminology scheme for the diagnosis of ...

Pancreatic histology reveals less fibrosis, less obliterative phlebitis, and infiltration by fewer IgG4 plasma cells. The histologic characteristic of subtype 2 is a granulocytic-epithelial lesion ...

Organs with tissue fibrosis and obliterative phlebitis, such as the pancreas, salivary gland and retroperitoneum, show clinical manifestations; AIP seems to represent one manifestation of IgG4 ...

storiform fibrosis (fibrosis in a cartwheel distribution), eosinophil tissue infiltration and obliterative phlebitis. Elevated serum IgG4 levels or eosinophilia may be present. Never miss a story ...
