A 6-year-old boy had a nonpruritic rash on his back for 10 days. There was no associated fever. The child's mother had placed a bandage over the lesions to prevent transmission to her other children.

Five days before this 1-year-old girl was brought to her doctor's office, a rash had developed on her left shoulder and the left side of her chest. The abrupt onset of a high fever (temperature, 41°C [105.8°F]) and irritability accompanied the outbreak of the rash. The child had a history of asthma and eczema.

After 3 months of seeing this painless mass at the angle of the 3-year-old's left jaw, his parents sought medical advice for their son. The youngster had no constitutional symptoms. A Mantoux test was performed, and an erythematous, indurated area measuring 15 mm in diameter was found at the test site 48 hours later.

Two 7-year-olds show the purpuric rash of the lower body and legs that is typical of Henoch-Schönlein purpura. This disease is a vasculitis that chiefly affects small vessels of the skin, joints, gastrointestinal tract, and kidney.

Exquisite pain of 3-days' duration in his right index finger sent a 19-year-old man for medical consultation. He recalled that a thorn had become embedded in the finger while gardening 1 week earlier.
