There are several asymptomatic skin diseases that favour the axillae. Most of the conditions in this month’s quiz are rather uncommon. Check the colour, and whether the surface is smooth (a patch) or thickened (a plaque).
Four examples of brown armpits, four examples of white armpits and four examples of skin coloured papules are included.
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.
What is wrong with this armpit?
Vitiligo
Is any treatment appropriate?
Completely white patches are likely to be due to vitiligo, and it is likely that other affected areas will be observed. Early treatment with a potent topical steroid may be of benefit, but it should not be used for more than a few weeks in case it causes unsightly stretch marks.
