Hemorrhages into the Pancreas

Albuminoid Degeneration of the Pancreas.

This is only found in combination with amyloid change in other organs of the body, and a diagnosis cannot be made.

Hemorrhages into the pancreas may be divided into three classes.

The most common form depends upon passive hyperæmia, the result of chronic diseases of the heart, lungs, or liver. In this condition the effusion of blood coexists with chronic inflammatory changes in the interstitial connective tissue. The appearance at first is of minute bloody points scattered throughout the areolar tissue; later, these change into round or oval pigment masses, or spaces containing reddish serum and surrounded by thickened, rust-colored, irregular walls.

The second class includes the rare cases of hemorrhage resulting from the rupture of one of the large blood-vessels of the gland, and due to some pre-existing change in the vessel walls. In these the pancreas is enlarged, may be converted into a sac containing blood, either fluid or coagulated or partially crystallized according to the duration of life after the hemorrhage has taken place, and a ruptured blood-vessel may be readily discovered on dissection.

The condition in which, without any evidence of passive hyperæmia or gross vascular lesion, the entire pancreas become hemorrhagic, constitutes the third class. The gland is then dark-red or violet in color, the meshes of the interstitial tissue are filled with recent or altered blood, and the acini are stained of a dull-gray hue. The hemorrhage may extend to the connective tissue surrounding the gland. Finally, the organ becomes soft, the peritoneal covering sloughs, and fragments of broken-down gland-tissue escape into the peritoneal cavity. These lesions are so analogous to those which attend thrombosis occurring in other organs that their dependence upon the same cause seems probable.

The first form of hemorrhage is unattended by special symptoms. In the second a pulsating tumor may suddenly appear in the epigastrium, and the ordinary indications of hemorrhage—vomiting, fainting fits, cold extremities, feeble pulse, and general exhaustion—are present. Death may occur suddenly or the patient may linger on for months. In the third condition death usually occurs very suddenly, probably from pressure upon the sympathetic ganglia. There are no symptoms, and the rapid termination prevents the development of general peritonitis, which would otherwise occur from the sloughing of the peritoneum.

There are no indications for treatment.
