[Cystic lymphangioma].

Lymphangioma is a benign, congenital type of tumour which can be classified as a malformation of the lymphatic vessels with an enlargement and a proliferation of same. It is divided, depending on the calibre of the vessels, into Capillary, Cavernous and cystic. 80% of these lesions are located in the neck; 50% of these cases are already evident at the moment of birth and 90% prior to the 2nd year of life. Its treatment is surgical but, due to the large number of digitations present, its complete removal is difficult to achieve, thereby giving rise to frequent relapses. We are submitting the case of a three and a half-year-old girl who was operated on in our department. With this, we would like to contribute to a greater knowledge of this pathology.
