Figure 1. Main histologic features (hematoxylin and eosin staining). (A) Diffuse lymphoplasmacytic inflammatory cell infiltrate in the ovary with areas of fibrosis (original magnification 100×). The infiltrate is angiocentric, as is apparent in the 2 vessels shown. (B) Original magnification 100×. In a high-power view, the infiltrate appears rich in plasma cells and eosinophils and there is accentuation around veins with involvement of the wall (phlebitis) and extension into the lumen with obliteration. (C, D) Original magnification 400×.
