Telangiectasia – 10 cases

This quiz tests your skills in identifying different types of telangiectasia in 10 cases.

Telangiectasia refers to permanently dilated small blood vessels (arterioles, capillaries and venules). They present as small linear, arborising, spider or papular red lesions. They may be congenital or acquired, and localised, unilateral or widespread. Genetic, hormonal and environmental factors may be important in their pathogenesis. Primarily of cosmetic significance, they may be safely ignored or treated by electrosurgery or, preferably, by an appropriate laser.

For each of the ten cases, study the image(s) and then answer the questions. You can click on the image to view a larger version if required.

Each case should take approximately 2 minutes to complete. There is a list of suggested further reading material at the end of the quiz.

When you finish the quiz, you can download a certificate.

Case 1

Make a diagnosis.

Spider naevus

What features distinguish this condition from other causes of telangiectasia?

The spider naevus (figure 1) represents localised telangiectasia with a central arteriole (the 'body') and radiating capillaries (the 'legs' of the spider). It is most often noted on face, arms, or upper trunk. Common at all ages and both sexes, they may be associated with pregnancy, oral contraceptives and liver disease.
