[Disseminated osseous angiomatosis in children].

The authors review 54 cases of diffuse bone angiomatosis (one new case and 53 from the literature) and describe the major clinical, radiological and anatomical features. The difficulties of distinguishing between haemagiomata and lymphangiomata are emphasised. The diagnosis is often helped by the presence of visceral or cutaneous lesions and when such lesions are found, a skeletal survey should always be done. These conditions, which may be classified under the general heading of angiodysplasias of bone, are hamartomata and must be distinguished from other bone lesions of vascular origin.
