Pseudohypopyon in acute myelogeneous leukemia.

An 11-month-old boy presented with uniocular hypopyon, elevated intraocular pressure, and iris nodules. A differential diagnosis of physical abuse, infection, retinoblastoma, juvenile xanthogranuloma, and histiocytosis X were considered but initial physical and laboratory investigations all had normal results. Three weeks following initial presentation, the child developed fulminant acute myelogenous leukemia. The clinical course, investigations, and outcome are reviewed.
