The medical opinion: Dr Lawrence Seymour, a consultant in acute medicine says: "A spider naevus (or angioma) is a benign skin blemish found on the face, neck, trunk or arms of 15 per cent of healthy adults.

A spider angioma (also known as a nevus araneus, spider nevus, vascular spider, and spider telangiectasia) is a type of telangiectasis found slightly beneath the skin surface, often containing a central red spot and reddish extensions which radiate outwards like a spider's web.
