Alveolar soft part sarcoma is a distinct clinicopathological entity of unknown histogenesis described by Christopherson et al1 in 1952. It commonly occurs in adolescents and young adults, and females are affected more often than males.2 Although frequently found in association with muscles of the extremities,3-5 it has also been encountered in other anatomic sites, including the orbit, where it appears to be an exceedingly rare tumor.6
The purpose of this paper is to report two cases of alveolar soft part sarcoma involving the orbit of a 10-month-old boy and a 3-year-old girl, both recently observed at the Unidad de Patología de la Facultad de Medicina de la Universidad Nacional Autónoma de Mexico, in the Hospital General.
