[Enigmatic lymphatic diseases involving the lung]

Lymphedema associated with other developmental malformations (Milroy syndrome, Hennekam syndrome, Noonan syndrome, Gorham-Stout syndrome, yellow nail syndrome) are unfrequent disease, but explorations led to the identification of genetic mutations that have then been validated in mouse models. However, lymphatic vessels complexity and its proximity with the venous system suggest the need for further researches, especially in the comprehension of pulmonary symptoms.
