Orbital involvement in nonendemic Burkitt lymphoma is rare. The authors report a unique case of a patient who sought treatment for extraocular muscle enlargement without a concurrent orbital mass, which subsequently led to the diagnoses of Burkitt lymphoma and acquired immune deficiency syndrome in an adult patient. The case report adhered to the principles of the Declaration of Helsinki and Health Insurance Portability and Accountability Act compliance. This single case report was institutional review board exempt, given that it does not meet the definition of human subjects' research.
