Egypt10 participantsStarted 2023-11-20
Plain-language summary
Lympho-vascular malformations result from errors in embryologic vasculogenesis involving capillaries, veins, arteries, lymphatics, or a combination of these. Infantile haemangiomas \& Vascular malformations like : Capillary malformations \& Venous malformations : they increase in size and never regress on their own. \& They are generally present at birth, they enlarge in response to infection, hormonal changes or trauma . Lymphatic malformations can be classified into macrocystic (cyst diameter \>1cm), microcystic (cyst diameter \<1 cm), or mixed , in macrocystic lymphatic malformations, surgery and sclerotherapy are effective . Surgery of microcystic lymphatic malformations remains challenging due to their infiltrative nature \& Sclerotherapy is often impossible. As especially large microcystic and mixed malformations are still a therapeutic challenge, pharmaceutical treatment as sirolimus is used in last years as main line of treatment with great efficacy.
