Fetal lymphangioma can be induced without labor if it can be treated; if it is difficult to be treated or more serious, induction of labor is recommended. Lymphangioma is a kind of congenital developmental abnormality, belongs to a type of malformation, mainly related to the abnormal development of primitive lymphatic sacs and lymphatic vessels in the process of fetal development, mostly seen in the neck, armpit, mouth and other parts of the body, and manifested as painless masses. If the lymphangioma does not affect the growth of the fetus after birth, or can be treated by surgical removal, it can be considered not to induce labor. If the lymphangioma affects the normal development of the fetus, or is difficult to treat after birth, such as limb hypertrophy, compression of the trachea and other symptoms, it is recommended to terminate the pregnancy in time and induce labor.
