lymphangioma
Pronunciation: lim-fan-jee-OH-mah
Benign lymphatic malformation commonly occurring in the head and neck region, particularly in pediatric patients.
Full Definition
Lymphangioma is a benign tumor-like malformation of the lymphatic system characterized by dilated lymphatic channels lined with endothelium. In head and neck oncology, these lesions most commonly affect the tongue, floor of mouth, and neck in pediatric patients. While benign, lymphangiomas can cause significant functional impairment including airway obstruction, feeding difficulties, and speech problems. Treatment typically involves surgical excision, though complete removal can be challenging due to the infiltrative nature of these lesions.
Usage
Usage note: Specify microcystic or macrocystic type when documenting lymphangioma characteristics.
