Extracted text: Case 1 A 20-year-old man presents for evaluation of a rash that he thinks is an allergic reaction. For the past 4 or 5 days, he has had the "flu," with fever, chills headache, and body aches. He has been taking an over-the-counter flu medication without any symptomatic relief. Yesterday he developed a diffuse rash made up of red, slightly raised bumps. It covers his whole body, and he says that it must be an allergic reaction to the flu medication. He has no history of allergies and takes no other medications, and his only medical problem in the past was being treated for gonorrhoea approximately 2 years ago. On further questioning, he denies dysuria or penile discharge. He denies any genital lesions now but says that he had a "sore" on his penis a few months ago that never really hurt and went away on its own after a few weeks so he didn't think much about it. On exam, his vital signs are all normal. He has palpable cervical, axillary, and inguinal adenopathy. His skin has an erythematous, maculopapular eruption covering his whole body including his palms and soles of his feet. No vesicles are noted. His genital examination is normal.
