Picture of Ataxia Telangiectasia (Ear)
Ataxia telangiectasia (A-T) is a genetic condition that causes neurodegeneration. People who have the condition first exhibit symptoms in early childhood including difficulties with balance, slurred speech, immune system problems, and ocular telangiectasia -- dilation of blood vessels in the whites of the eyes that causes redness. The spider vein formations, or telangiectasias, appear on the cheeks, ears, and whites of the eyes. The photo depicts a telangiectasia on the ear of an affected patient. People with A-T have an increased predisposition to cancer.
