His parents denied that he had any trauma or fever. On physical examination, he was afebrile in no apparent distress. His left knee was swollen and tender (Figure 175-1). He admitted to other joint pains but there was no swelling or tenderness in the other joints. The pediatrician noted a petechial and purpuric eruption from his buttocks down to his ankles (Figure 175-1). It was non-blanching but only barely palpable. There were prominent circumferential petechiae around the left sock area. Upon further questioning, the mother admitted that her son had a viral upper respiratory infection 2 weeks ago. A urinalysis showed mild hematuria but no proteinuria. He never developed abdominal pain. Therapy was supportive and systemic corticosteroids were not used.
