[Mesenteric cystic lymphangioma associated with necrosis of the Bauhin's valvula in children].

Mesenteric Cystic Lymphangiomas is a rare benign tumor. The first case was described after an autopsy in 1507 by Benivieni, an anatomist from Florence. In 1880 by Tillaux. Since then many cases have been described.
