Hypopyon commonly manifests in infections and autoimmune diseases such as Behcet’s disease, but rarely occurs in patients with acute leukemia. In this case, a 5-year-old girl was diagnosed as having hypopyon by a local physician and referred to our hospital for a definitive diagnosis. She was diagnosed as having B precursor acute lymphoblastic leukemia (ALL), with central nervous system invasion. The patient underwent iridectomy to decrease the intraocular pressure in the left eye, and ALL cells were observed in the iris. Following treatment, she remained in complete remission for 7 years. Hypopyon in patients with acute leukemia is often observed at the time of relapse, but is rarely detected at the initial stage. Regular follow-up for recurrence is necessary owing to the limited transport of anticancer drugs to the eyes.
