We report for the first time three siblings with cat-scratch disease occurring simultaneously. Case 1 was an 8-year-old boy with enlarged supraclavicular lymph nodes and fever. Case 2 was the 11-year-old sister whose presentation was a prolonged febrile illness. Case 3 was a 13-year-old male adolescent with adenitis of the neck and thigh. All three patients were treated with rifampin with improvement of their symptoms.
