Immunohistochemical profile of Myogenin and MyoD1 does not support skeletal muscle lineage in alveolar soft part sarcoma: A study of 19 tumors
Sarcoma, Alveolar Soft Part
Soft Tissue Neoplasms
Cytoplasmic staining with MyoD1 in alveolar soft part sarcoma may correspond to cross-reactivity with an undetermined cytoplasmic antigen. The lack of immunostaining with myogenin, MyoD1, desmin, and muscle-specific actin provides evidence against a myogenic origin for alveolar soft part sarcoma.
