Lymphatic malformations are abnormal growths of the lymphatic system, which is a network of vessels that help transport lymph fluid throughout the body. These malformations can occur anywhere but are most commonly found in the head, neck, and axillary regions. They can appear as soft, painless swellings and may vary in size. These conditions are usually present at birth or develop in early childhood. Lymphatic malformations can be classified into different types, such as lymphangiomas and cystic hygromas. Treatment options may include observation, surgical removal, or other interventions to manage symptoms and improve quality of life.
