ABSTRACT
This chapter presents the case study of a 62-year-old man. A 62-year-old man presents to the accident and emergency department with a 2-day history of an asymptomatic skin eruption appearing mainly on his trunk and limbs. It seems to have started after visiting his local swimming pool and he had wondered if the chlorine in the water may have triggered the skin rash. He is otherwise fit and well but has recently had a sore throat and temperature but no cough. He has no previous history of skin problems. He is referred to the on-call dermatology team. There is a widespread eruption mainly on the lower limbs and trunk but also to a lesser extent on his arms. The morphology of the rash is purple and non-blanching; lesions are starting to coalesce and are mainly macular but some are popular. His tonsils are erythematous with some surface exudate and he has tender cervical lymphadenopathy.
