title: Bilateral exopthalmus due to retro-orbital chloromas in a boy with t(8;21)- positive acute myeloblastic acute leukemia.
abstract: Exophthalmus is an infrequent finding in pediatrics. The differential diagnoses include chloromas, tumors of immature hematopoietic precursor cells. The case of a child with acute myeloid leukemia is reported. The presenting signs had included exophthalmus and nasal speech due to retro-orbital and sinusoidal chloromas, respectively. As in most cases of pediatric acute myeloid leukemia with chloroma, the AML1/ETO fusion gene was found, which portended a not unfavorable prognosis. This child was treated according to the AML-BFM 98 protocol and achieved an ongoing remission. The exophthalmus resolved completely.
