title: Immunohistochemical study of embryonic rhabdomyosarcomas.
abstract: 11 orbital embryonic rhabdomyosarcomas were studied immunohistochemically from patients under 4 years of age. One out of these cases, undifferentiated, showed to be myoglobin negative, and desmin positive. We point out the importance of this fact in immunohistochemical determination of the specificity of this entity.
