NCI Definition: An aggressive malignant mesenchymal neoplasm with skeletal muscle differentiation, occurring in adults and rarely in children. The tumor is characterized by the presence of bizarre round, spindle, and polygonal cells. Clinical presentation includes a rapidly enlarging painful mass usually of the lower extremities. [1]

Pleomorphic rhabdomyosarcomas most frequently harbor alterations in TP53, RB1, NF1, PTEN, and DNMT3A [2].

Most Commonly Altered Genes in Pleomorphic Rhabdomyosarcoma

TP53 c.217-c.1178 Missense, TP53 Mutation, TP53 Missense, RB1 Loss, and CREBBP Mutation are the most common alterations in pleomorphic rhabdomyosarcoma [2].
