Pancreatic KHE. a H&E stained sections of tumor showing predominantly glomeruloid arrangement in this field. These glomeruloid nodules are composed of closely packed vascular channels lines by single layer of bland endothelial cells. b This area shows predominantly spindle cell growth, infiltrating into the pancreatic acini. These areas resemble KS. c Other areas of spindle cell growth surrounding lining of a pancreatic duct, where the spindled endothelial cells grow in sheets with slit like lumina containing variable number of erythrocytes. d Focus of perineurial invasion
