Bilateral anterior and posterior scleritis in a patient with acute myelogenous leukemia

Purpose: To report a novel case of bilateral anterior and posterior scleritis in a patient with acute myelogenous leukemia (AML). Observations: A 69-year-old African American man was admitted to the hospital for relapse of AML. After admission, but prior to induction of chemotherapy, the patient developed ocular redness and proptosis. The diagnosis of bilateral anterior and posterior scleritis was made following an ophthalmic examination, infectious and autoimmune lab work-up, and neuroimaging. The patient was administered immunosuppressive therapy, clinically monitored, and initiated on chemotherapy for AML relapse. About one week later, the patient showed clinical improvement and resolution of the scleritis and proptosis. Conclusion: Scleritis may present during AML relapse, and it may be due to a paraneoplastic syndrome or a reactive anti-leukemic inflammatory response. Clinicians should monitor patients with AML relapse for symptoms such as ocular redness, proptosis, pain, photophobia, and decreased vision, which may indicate development of scleritis.
