Lesions on the ear – 10 cases

This quiz will test your diagnostic skills in diagnosing lesions on the ear.

Accurate diagnosis of lesions on the ear requires a careful history, thorough skin examination in a good light, and sometimes a biopsy. Inflammatory and neoplastic conditions may appear similar, often presenting as scaly or ulcerated plaques or nodules.

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

Discoid lupus erythematosus

Discoid presents as irregular erythematous scaly plaques on nose, cheeks, ears, lips and elsewhere. They are characterised by 'carpet-tack' (follicular) scaling, dyspigmentation and scarring. Open comedones within the concha are common.

Management may include topical steroids, topical calcineurin inhibitors, oral antimalarials and, in severe cases, systemic steroids or other immunosuppressive agents. Sun protective measures are important.
