[Ocular relapse of acute lymphoblastic leukemia]

A bilateral leukemic hypopyon can be inaugural in the child's leukemia or reveal a relapse. A five years old child with acute lymphoblastic leukemia presented after 30 months of treatment a bilateral hypopyon. Anterior chamber paracentesis with cytological survey revealed leukemic cells and confirmed the ocular relapse. The treatment included the association of topical corticosteroids, chemotherapy and radiotherapy. This child died unfortunately 16 months later following a medullar relapse. We remind the different clinical aspects of leukemic invasion of the anterior segment and the therapeutic methods for this relapse.
