NCI Definition: A rapidly growing malignant mesenchymal neoplasm. It is characterized by the presence of round cells with myoblastic differentiation and a fibrovascular stroma resembling an alveolar growth pattern. The tumor usually presents in the extremities. [1]

Alveolar rhabdomyosarcomas most frequently harbor alterations in FOXO1, PAX3, MYCN, PAX7, and MYCL [2].

Most Commonly Altered Genes in Alveolar Rhabdomyosarcoma

FOXO1 Fusion, PAX3-FOXO1 Fusion, FOXO1-PAX3 Fusion, MYCN Amplification, and PAX7-FOXO1 Fusion are the most common alterations in alveolar rhabdomyosarcoma [2].
