Answers
EASY These are usually easy to diagnose but can cause confusion when they occur in an atypical site, such as around the eyes. Most resolve within 18 months or so and specific treatment is not usually recommended. In this situation, though, intervention would be warranted and would require referral to an ophthalmologist.
MODERATE This is caused by infection with a pox virus, usually in those who have come into contact with sheep. The result is a sore, ulcerating nodule typically on the hands or arms, which may cause lymphangitis or lymphadenopathy. Most lesions resolve spontaneously after about six weeks.
HARD This is a febrile vasculitis that affects children usually under the age of five years. It comprises a fever lasting more than five days, with a rash, conjunctivitis, cracked lips, enlarged cervical glands and changes in the hands and feet (initially reddening and swelling, then desquamation). These children need urgent paediatric assessment as they can be very unwell and can suffer cardiac complications.
