Capillary telangiectasia is a medical condition that causes small blood vessels to dilate and form clusters on the skin or within organs. There are several synonyms for this condition, which include spider angioma, spider nevus, and Campbell de Morgan spot. These terms describe the appearance of the clusters, which can look like spider webs or red dots on the skin. Capillary telangiectasia can also be referred to as a vascular lesion or vascular malformation. While most cases of capillary telangiectasia do not cause any symptoms, in some cases, they can be associated with liver disease or brain abnormalities. As with any medical condition, it is important to seek medical attention if you are experiencing any concerning symptoms.
