Lymphangiomas are benign tumors of the lymphatic system, which can develop anywhere but usually in the neck, head, or arms. They can develop congenital or be acquired. Congenital lymphangiomas are due to poor connection of lymphatic channels to the main lymphatic drainage duct during prenatal life, whereas acquired lymphangiomas are due to interrupted normal lymphatic drainage following surgery, malignancy, Trauma, or even radiotherapy.
Symptoms of lymphangioma include a swollen area on the skin, discomfort when the tumor is touched, and difficulty moving affected body parts. Lymphangiomatosis is a condition characterized by multiple tumors throughout the lymphatic system.
