Abstract

A typical angioma simplex is composed of new-formed, very tortuous blood-vessels, held together by a small amount of connective tissue and situated usually in the skin, e. g., nevus. The normal vessels of the part where it is situated may enter more or less into its formation, becoming dilated and tortuous, and it has therefore become customary to include in the class of angiomata tumors composed entirely of dilated pre-existent vessels, although the term telangiectasis or telangiectoma is by some preferred to this sort of angioma where dilatation is more prominent than actual new formation.

A typical angioma cavernosum is composed chiefly of blood spaces lined with endothelium, separated by a stroma of connective tissue. The spaces contain venous blood, but seem to represent capillaries, being interposed between arteries and veins. The structure is similar to that of the corpus cavernosum. Such are often found in the liver.
