Anaplastic rhabdomyosarcoma, previously called pleomorphic rhabdomyosarcoma, is the least common of all subtypes. It most often occurs in patients aged 30-50 years. It is rarely observed in children. Anaplastic rhabdomyosarcoma is defined by large, lobate hyperchromatic nuclei and multipolar mitotic figures.
