Normal subcutaneous tissue with hairs, sweat ducts, blood vessels, muscular tissue, etc. connective tissue matrix in which are numerous cells. This ANGIOMA 6S5 angiomatous tissue extends from the cutis vera into the musculartissue beneath, and is sharply separated from the surrounding tissues,though here and there small bundles of fibrous tissue may be seenprojecting into the vascular or capillary mass. (X 300).—The structure of the small vessels with their well-defined endothelial lines can easily be made out. Where the vesselsare very small the tissue is markedly cellular, many of the cellsbeing apparently of endothelial origin, though plasma cells and
