A rare congenital condition in which blood vessels and/or lymph vessels fail to form properly. The main features are nevus flammeus (port-wine stain), venous and lymphatic malformations, and soft-tissue hypertrophy of the affected limb.
A pathologic dilation of lymph vessels characterized by chronic diarrhea and loss of proteins.
A lymphatic malformation, usually occurring in young children and involving the head and neck. It may be congenital or acquired. Congenital lymphangiomas are often associated with chromosomal abnormalities such as Turner syndrome, although they can also exist in isolation. Lymphangiomas are commonly diagnosed before birth using fetal ultrasonography. Acquired lymphangiomas may result from trauma, inflammation, or lymphatic obstruction.
A condition of localized fluid retention and tissue swelling caused by a compromised lymphatic system. The lymphatic system returns the interstitial fluid to the thoracic duct and then to the bloodstream, where it is recirculated back to the tissues. Tissues with lymphedema are at risk of infection.
