This quiz tests your diagnostic skills for blistering conditions affecting the feet.
Blisters are relatively common findings on one or both feet. They are formed by intraepidermal or subepidermal cellular separation. This may arise because of mechanical injury, infection, or immunological reaction to exogenous or autogenous factors. The blisters may be filled with clear or haemorrhagic fluid or pus.
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.

When you finish the quiz, you can download a certificate.
What is the cause of the blistering?
Cutaneous larva migrans
Describe the clinical features of this condition.
The majority of cases of cutaneous larva migrans are in travellers to the tropics, and are caused by larvae of the dog or cat hookworm (Ancylostoma brasiliense). The larvae penetrate the skin resulting in bizarre tortuous tracks.
