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).
Differential diagnosis of Klippel-Trenaunay-Weber syndrome in which PWSs are seen in extremities and face, hemihypertrophy of soft and bony tissues, and Beckwith-Wiedemann syndrome along with facial PWS, macroglossia, omphalocele, and visceral hyperplasia, other lesion syndrome, and coats disease were considered.
(3) The difference between KTS and Klippel-Trenaunay-Weber Syndrome (KTWS) is that the latter includes significant arteriovenous malformations in the affected extremity.
When arteriovenous malformations coexist Klippel-Trenaunay-Weber syndrome (or Parkes-Weber) can be diagnosed [3].
Two cases had soft-tissue masses, of which one had Klippel-Trenaunay-Weber syndrome and the other a facial teratoma, both diagnosed antenatally.

Klippel-Trenaunay-Weber syndrome (KTWS) is characterized by a triad of port-wine stain, varicose veins, and bone and soft tissue hypertrophy involving an extremity [1].
Hemangiomas are often related to some systemic hereditary diseases such as blue rubber bleb naevus syndrome, Maffucci's syndrome, Klippel-Trenaunay-Weber syndrome (Mako, 1996; Golitz, 1980).
A myriad of syndromes are characterized by substantial localized or asymmetric tissue overgrowth, represented by Beckwith-Wiedemann syndrome, Sotos syndrome, Proteus syndrome, Klippel-Trenaunay-Weber syndrome, Madelung's disease, neurofibromatosis type I, Weaver syndrome, Nevo syndrome, Simpson-Golabi-Behmel syndrome, Bannayan-Riley-Ruvalcaba syndrome, Perlman syndrome, Pallister-Killian syndrome, and many other conditions.
The differential diagnosis for this disorder includes Beckwith-Wiedemann Syndrome, Klippel-Trenaunay-Weber Syndrome, Neurofibromatosis, lymohangiomatosis, hemangiomatosis, and Mafucci's Syndrome.
