Lymphangioma is a benign tumor of the lymphatic vessels, which is a congenital malformation of them (expansion and irregular arrangement). Usually observed in children, often on the face, neck, chest, in the armpit, on the mucous membranes of the lips, tongue and cheeks. It has the appearance of a soft, elastic cystic tumor with skin thinning over it.
Treatment of lymphangioma - surgical removal of the tumor.
Lymphangioma (lymph + Greek. Angeion - vessel) - a neoplasm of lymphatic vessels. True lymphangiomas are very rare tumors. Most lymphangiomas are malformations. Lymphangiomas can be localized in all tissues, most often in the skin, neck, retroperitoneal space, mesentery, very rarely in the liver, spleen, kidneys. According to the structure distinguish diffuse, cavernous and cystic lymphangiomas.
Diffuse lymphangioma is characterized by enlarged lymphatic crevices lined with endothelium and filled with lymph; These gaps are located in dense fibrous connective tissue containing bundles of smooth muscle fibers and adipose tissue. Being located in the tongue, lip, they give them large sizes (macroglossia, macrocheilia).
Cavernous lymphangiomas consist of lymph-bearing cavities with more or less thick walls of fibrous tissue with bundles of smooth muscle fibers.
Cystic lymphangiomas are single-chamber or multi-chamber (usually in the neck, in the armpit), their cavities are lined with a thin layer of endothelium. The so-called hypertrophic lymphangiomas are also described, in which the walls of the cavities are thickened due to reproduction of the endothelium in several layers. They represent the transition to true tumors - lymphangioendotheliomas.
Clinically, lymphangiomas are characterized by small soft swellings in the skin or subcutaneous tissue, disappearing under the pressure of a finger. Cystic lymphangiomas usually represent a conglomerate of cystic cavities ranging from a pinhead to huge tumors (often on the neck, in the subcutaneous tissue, groin, popliteal fossa, sometimes in the mesentery) of a soft consistency. Their growth is slow. Lymphangiomas easily inflamed and suppurate.
Treatment - removal of the tumor. Diffuse lymphangioma is not always possible to extirpate completely.
Lymphangioendotheliomas tend to recur after surgery.
