Skeletal-extraskeletal angiomatosis is defined as a benign vascular proliferation involving the medullary cavity of bone and at least one other type of tissue. It has also been known as cystic angiomatosis in which multiple cystic lesions are scattered diffusely throughout the skeleton often with similar angiomatous changes in other tissues, usually the spleen.

A case of skeletal angiomatosis in association with gastro-intestinal angiodysplasia and paraproteinemia is reported.
