[Milk spots on the parietal peritoneum over the pancreas in the mouse (author's transl)]

In adult dd-mice of both sexes, milk spots on the parietal peritoneum over the pancreas were studied by light and transmission and scanning electron microscopy. The milk spots appeared like a leaf with a slender stalk adhering to the peritoneum or like a flat or disc-shaped mass on the pancreas. They varied in number from case to case, but they were, on the average, 2.1 +/- 0.6 in males and 4.0 +/- 0.7 in females. They were supplied with capillary vessels which had fenestrated endothelium. The milk spots were the same in structural details as the omental type I spots preveiously described.
