Why is it called Klippel-Trènaunay-Weber syndrome?

In 1900 the French physicians Maurice Klippel and Paul Trènaunay reported the case of a patient with a port-wine stain, asymmetrical overgrowth (hypertrophy) of soft tissue and bone together with hemangiomas of the skin In 1907, the eminent London physician F. Parkes Weber reported three more cases, and noted the varicosities. As is often the case in medicine, those who describe a syndrome are often given credit by having the syndrome named after them. Thus, in 1918 it became know as Klippel-Trènaunay-Weber syndrome.
