Purpose:
To report a case of acute myeloid leukemia with bilateral proptosis as the sole presenting sign.
Design:
Observational case report.
Methods:
A patient with bilateral proptosis was seen in consultation by pediatric ophthalmology.
Results:
Complete blood count, computerized tomography, and bone marrow biopsy confirmed the diagnosis of acute myeloid leukemia, with the proptosis due to diffuse infiltration of all extraocular muscles.
Conclusion:
In a child with the sudden onset of proptosis without any other systemic findings, the diagnosis of acute leukemia must be considered.
