Overview
Rhabdomyosarcoma may be classified according to the "International classification of rhabdomyosarcoma" into five subtypes: Alveolar rhabdomyosarcoma, embryonal rhabdomyosarcoma, botryoid rhabdomyosarcoma, spindle cell rhabdomyosarcoma, and anaplastic rhabdomyosarcoma.
Classification
Multiple classification systems have been proposed for subclassifying rhabdomyosarcomas. The most recent classification system, the "International classification of rhabdomyosarcoma", was created by the Intergroup Rhabdomyosarcoma Study.[1] This system attempts to combine elements of the previous systems and correlate these with prognosis based on tumor type. Rhabdomyosarcomas are classified into five subtypes:
- Alveolar rhabdomyosarcoma
- Usually affects young adults
- Early metastasis is common
- Embryonal rhabdomyosarcoma
- Usually affects children <10 years of age
- Typically locally invasive
- Botryoid rhabdomyosarcoma
- Spindle cell rhabdomyosarcoma
- Anaplastic rhabdomyosarcoma
Several additional subtypes of rhabdomyosarcoma exist that do not fit into the International Classification scheme:
- Pleomorphic rhabdomyosarcoma: Usually occurs in adults rather than children.
- Sclerosing rhabdomyosarcoma: It is a rare rhabdomyosarcoma subtype.
