Venous malformation
Clinical signs
  • age: inborn, but diagnosed usually in adults
  • location: variable, usually deep soft tissue
  • complex formations, affecting skin, muscle, bone, joints
  • x-ray: venograms required for diagnosis (slow venous flow); sometimes calcifications; often bone abnormalities (thinning, demineralization, hypoplasia, sometimes osteolysis
  • size: usually large; varricosities, venous dilatations and cutaneous spongiform masses
  • worsens during the life
  • dilates during exercise, strain or in vertical position
  • often painful
  • sometimes disorders of hemocoagulation

Histology

Variable, often large, thick walled venous blood spaces, thrombi, calcifications, variable dilatation of the venous spaces. Connective tissue, fat, muscle usualy separates the blood vessels. Large vascular spaces often dissect the connective tissue and its structures.
