Figures & data
1 Mature epithelial nests and cysts, containing squamous, respiratory, and simple epithelia, embedded within mature fibrous mesenchymal tissue (H&E, ×200).
2 Many stromal capillaries highlighted by staining for von Willebrand's factor (bottom, gland with mucinous epithelium).
3 Most of the stromal area is deficient in capillaries (some are present in the upper area of the stroma). Stain for von Willebrand's factor.
4 CT scans with contrast enhancement obtained before initiation of interferon therapy and during the course of interferon therapy, showing from moderate to significant amounts of ascites flanking the liver and spleen. Note some tiny calcifications and a few foci of soft tissue attenuation within the peritoneal fluid.
