Sarcoma mieloide orbitario como primer signo de presentación de leucemia mieloide aguda en un paciente pediátrico: reporte de caso

Abstract

Myeloid sarcoma (MS) is a rare extramedullary tumor composed of immature myeloid cells that may occur in association with acute myeloid leukemia (AML). It is more common in children than in adults, and the orbit represents one of the most frequent sites of involvement. When MS presents as an isolated lesion or precedes the diagnosis of AML, accurate diagnosis may be challenging, potentially delaying treatment and adversely affecting prognosis. We report a case of orbital MS as the initial manifestation of AML in a previously healthy pediatric patient with a rapidly progressive clinical course.
