Lymphangioma - benign tumor of the lymph vessels, representing a congenital malformations of them (expansion and the wrong location). Usually seen in children, often on the face, neck, chest, underarm, on the mucous membranes of the lips, tongue and cheeks. Looks soft, elastic chistovodnoe tumors with thinned over her skin.

Lymphangioma (lymph + GK. angeion - vessel) - a tumor of the lymphatic vessels. True lymphangioma - very rare tumor. Most HP is a malformation. L. can be localized in all tissues, most commonly in the skin, neck, retroperitoneal space, the mesentery, very rarely - in the liver, spleen, kidneys. According to the structure there are diffuse, cavernous and cystic L.
Diffuse L. characterized extended lymph slots lined with endothelial tissue and filled with lymph; these cracks are located in the dense fibrous connective tissue containing bundles of smooth muscle fibers and adipose tissue. Located in the tongue, lip, they give them a large size (macroglossia, macrocheilia).
Cavernous lymphangioma consist of lymph cavities with more or less thick walls of fibrous tissue with bundles of smooth muscle fibers.
Cystic L. can have one or more multi (most often on the neck, armpit area), the cavity of them are lined with a thin layer of endothelium. Described even the so-called hypertrophic L. in which wall cavities thickened over harvesting of endothelium in several layers. They represent the transition to the true tumors - lymphangiectasia.
Clinically of lymphangioma are characterized by small soft swelling in the skin or subcutaneous tissue, disappearing under the pressure of a finger. Cystic L. usually represent a conglomerate of cystic cavities in the magnitude of a pinhead to huge tumors (often on the neck, in the subcutaneous tissue, groin, the popliteal fossa, sometimes in the mesentery) the soft consistence. Growth is slow. L. easily inflamed and nagnaivajutsja.
Treatment - removal of the tumor. Diffuse lymphangioma not always possible to exterminate completely.
Lymphangiectasia tend to recur after surgery.
