Human granulocytic ehrlichiosis (HGE) is an emerging infectious disease tha
t primarily affects adults. Typical clinical features include fever, headac
he, and myalgias. This case represents the youngest reported patient with H
GE. Her clinical presentation was unusual in that she presented with severe
abdominal pain. In addition, she did not develop the typical spectrum of l
aboratory abnormalities that has been reported in adults. This patient's co
urse suggests that the presentation of HGE may be more varied than previous
ly reported.
