Acute myeloid leukemia presenting as bilateral proptosis from diffuse extraocular muscle infiltration.

Objective: To report a case of acute myeloid leukemia with bilateral proptosis as the sole presenting sign.

Methods: 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.

Conclusions: In a child with the sudden onset of proptosis without any other systemic findings, the diagnosis of acute leukemia must be considered.
