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 2

Make a diagnosis.

Linear facial telangiectasia

What features distinguish this condition from other causes of telangiectasia?

Red linear and arborising telangiectasia frequently occurs on the face, particularly on the nose, cheeks, and chin. It is due to genetic predisposition, hormonal factors and chronic sun exposure. It is more noticeable with increasing age. The vessels tend to be more prominent in males, especially on the sides of the nose. Facial telangiectasia may be a predisposing factor for rosacea or arise as a consequence of chronic inflammation.
