Lymphangioma, also known as cystic hygroma, is a benign proliferation of tumored lymph vessels, and is rare. However, the tumors are important to recognize because they may mimic many vascular tumors including angiosarcomas and Kaposi's sarcoma.

These tumors may occur anywhere but usually present in the head and neck in children and infants. Visceral organs such as the lungs and gastrointestinal tract may also be involved. In the soft tissue, these tumors may be present as a soft fluctuant mass that varies in size.

The tumor is a benign neoplasm or hamartoma arising from lymphatic vessels, manifesting as a raised, soft, shaggy, bubbly, pinkish-white lesion; cosmetic considerations may warrant attempted removal of lymphangiomas.
