Clinical Case:
A 69-year-old man with a history of acute myeloblastic leukemia-M1 presented with bilateral conjunctival injection. Ophthalmological examination revealed lesions located at the upper tarsal conjunctiva of the right eye and lower tarsal conjunctiva of both eyes. Histological and immunohistochemical studies confirmed conjunctival myeloid sarcoma. The patient died due to multiorgan failure three months later.
Discussion:
Extramedullary recurrence of leukemia can appear as an ocular manifestation that brings about a recurrence of the leukemia, leading to a poor prognosis.
