Abstract
The cases of 2 siblings with cat scratch disease are described who presented with symptoms suggestive of acute febrile gastroenteritis. The first patient, a 7.5-y-old girl, developed mesenteric lymphadenitis, hepatosplenic granulomas and osteolytic bone lesions only late in the course of her protracted illness. Her 3-y-old brother had a shorter, self-limited illness without complications. Cat scratch disease is often unrecognized and the full spectrum of its clinical manifestations remains to be investigated.
