Mycoplasma pneumonia and atypical acute hemorrhagic edema of infancy

Abstract Acute hemorrhagic edema of infancy is a benign rare presentation of leukocytoclastic vasculitis that affects children between 4 and 24 months of age. It usually involves the distal extremities, face, and ears. We report an atypical presentation of AHEI in a 1 year 5 months old boy starting initially over the trunk and back, then spreading to the face and extremities. Mycoplasma pneumonia IgM was found to be positive. The rash resolved spontaneously within two weeks. Herein we present a case of Mycoplasma induced AHEI with an atypical clinical presentation followed by a review of the literature.
