A rhabdomyosarcoma composed of embryonic and alveolar components. It is characterized by the presence of spindle cells with myoblastic differentiation, a myxoid stroma, and fibrous septa. These tumors were previously considered variants of alveolar rhabdomyosarcoma. The lack of PAX3-FOXO1 fusions in most of these tumors suggests that are biologically and clinically related to embryonal rhabdomyosarcoma.
No clinical trials have been registered for rhabdomyosarcoma with mixed embryonal and alveolar features.
6 publications have been identified in PubMed for rhabdomyosarcoma with mixed embryonal and alveolar features. Research spans Case Report / Case Series (50%), Review / Meta-Analysis (33%), and Epidemiology / Natural History (17%).
