As fall approaches, mothers start bringing their kids into the clinic for routine check-ups and vaccinations. One mother brings her eight year old son in. On exam, you find tender lymph nodes along the neck and axilla on the left. He says it hurts when you palpate them. You see this on his left shoulder:
You notice the child has a mild fever. You ask him about symptoms and he just says, "I feel sick." You look at the mother. She says, "I think he's faking it to get out of going to school. You should have seen him playing with his grandmother's kittens two weeks ago. He was full of energy."
