Spider naevi
System: Skin & Nail Signs · All skin & nail signs
What it is — and how it is elicited
A small central red spot with fine blood vessels radiating out like a spider's legs; pressing the centre makes the whole lesion blanch and refill.
What a positive finding suggests
A few can be normal, especially in children and pregnancy; many are associated with liver disease and raised oestrogen levels.

Please note: This page is an educational reference about clinical examination signs. A clinical sign supports — and never replaces — a full clinical evaluation, examination and appropriate testing. A sign being present does not by itself prove a diagnosis, and an absent sign does not rule one out. If you have symptoms that worry you, see a health professional.
