Intraocular histiocytic lymphoma: a pediatric case presentation

An 11-year-old white female with a 5-month history of stage IV systemic histiocytic lymphoma presented in relapse with a red, painful left eye with a decrease in visual acuity. A diagnostic anterior chamber paracentesis was performed revealing cells consistent with the systemic diagnosis of histiocytic lymphoma. Also, at that time, central nervous system involvement was found. This is the youngest patient to our knowledge to have documented intraocular involvement from histiocytic lymphoma. She is also unusual in that the ocular involvement was predominantly localized to the anterior segment.
