Klip·pel-Tre·nau·nay-Web·er syn·drome

(klĭ-pel' trā-nō-nā web'ĕr), [MIM*149000]
a combination of angiomatosis (usually nevus flammeus and nevus avanus) and associated with enlargement and venous anomalies of an affected limb. Limb changes affect muscle and bone (atrophy or enlargement). Lymphedema bladder involvement may occur. Inheritance is probably autosomal dominant and sporadic.

Klippel-Trenaunay-Weber syndrome

A congenital disease (OMIM:149000) characterised by malformations of capillary (98% of patients), venous (72%) and lymphatic (11%) vessels, as well as bony and soft tissue hypertrophy, leading to large cutaneous haemangiomas with hypertrophy of the related bones and soft tissues.

Molecular pathology
Defects in AGGF1 on 5q13.3, which encodes a protein that promotes angiogenesis and endothelial cell proliferation, are a cause Klippel-Trenaunay syndrome. Other potential Klippel-Trenaunay-Weber syndrome gene loci have been identified at 8q22.3 and 14q13.

Klippel-Trenaunay-Weber syndrome

Angio-osteohypertrophy A usually sporadic, occasionally AD condition characterized by hypertrophy of extremities, port-wine stains, and venous malformations, syndactyly and polydactyly. See Syndactyly.

The ISSVA classification is useful for identifying clinical landmarks, because some of the entities are associated with skin lesions, as is the case for hereditary hemorrhagic telangiectasia, Klippel-Trenaunay-Weber syndrome, Parkes-Weber syndrome, while other entities do not include lesions of the skin, for example angiodysplasia and arteriovenous malformations (Lowe et al 2012).
3) The difference between KTS and Klippel-Trenaunay-Weber Syndrome (KTWS) is that the latter includes significant arteriovenous malformations in the affected extremity.
