Truncal Varicosities and Bilateral Port-wine Stain with Spinal Deformities Associated with Klippel–Trenaunay–Weber Syndrome

Klippel–Trenaunay–Weber syndrome (KTWS) is a rare congenital disorder characterized by asymmetric limb hypertrophy, usually of the lower limbs, as well as vascular anomalies and capillary malformations under the skin, termed as port-wine stain. KTWS is prevalent in all parts of the world. It has a high degree of diversity of the associated malformations. In the present case, vascular/lymphatic malformations were evident by the presence of bilateral port-wine stain and lymphangioma. More interestingly, prominent aberrant veins (truncal varicosities) were found in the anterior chest wall, together with the presence of multiple angiolipomatosis. Bone deformities were more than limb hypertrophy and macrodactyly and extended to spinal deformities in the form of scoliotic changes.
