a tumor of the lymphatic vessels.

Most lymphangiomas represent defects of development. They may be localized in any part of the body and its organs and tissues, but they are found most often in the neck, skin, subcutaneous connective tissue, or retroperitoneal space (less frequently, in the liver, spleen, or kidneys). They appear as soft swellings of various dimensions in the skin or subcutaneous tissue and seem to disappear when pressed. Lymphangiomas grow slowly. They become inflamed readily. Treatment is surgical.

Histologically, a lymphangioma can be a well-circumscribed lesion composed of 1 or multiple large cysts, which can interconnect.[8] These are typically called a cavernous lymphangioma. A lymphangioma can also be composed of microscopic cysts producing an ill-defined, compressible, spongelike lesion, known as a cystic lymphangioma.[2] The walls of the small or large lymphatic spaces are thin and contain fibrous tissue, smooth muscle, and aggregates of lymphoid tissue.
