A type of tumor that mainly consists of blood vessels or lymph vessels, often appearing as a growth on the skin or in other tissues.
The doctor diagnosed her with an angioma on her arm.
Angioma is formed from "angio-" (from Greek "angeion", meaning vessel) and "-oma" (from Greek "oma", meaning tumor or swelling). The word refers to a tumor or growth that is related to blood vessels or lymphatic vessels.
Think of 'vessel' ('angio-') and 'tumor' ('-oma') to remember that an angioma is a growth related to blood vessels.
