[Orbital embryonal rhabdomyosarcoma in adults. Report of 2 cases].

Rhabdomyosarcoma (RMS) is the most frequent sarcoma of infancy. Embryonal RMS is generally correlated with a better response to chemotherapy. In the present paper two cases of embryonal RMS of the orbit affecting adult patients are reported. Both patients are male, aged 22 and 24 years respectively. In Case 1 the lesion arose primitively in the orbit, in Case 2 the orbit was affected by secondary involvement. Both patients presented a rapid response to chemotherapy, with reduction of the neoplastic mass and regression of symptoms.
