Rhabdomyosarcoma can be broadly classified into different subtypes, namely the embryonal, the alveolar, the sclerosing/spindle cell, the rarer pleomorphic subtype, mixed subtypes, not otherwise specified RMS and last RMS with anaplasia. In some subtype further sub classifications can be distinguished: 2.4.1.1.
Feb 12, 2024 · Rhabdomyosarcoma is classified into histologic subtypes: embryonal, alveolar, pleomorphic, spindle, and mixed-type. Embryonal is the most commonly occurring subtype and also has the best prognosis. The management approach is tailored to a patient's risk stratification.

Feb 6, 2019 · Embryonal and alveolar rhabdomyosarcoma (ERMS, ARMS) are subtypes of RMS that mainly occur in children, with relatively good outcomes. The incidence in adults is extremely low and survival is significantly worse compared with children.
embryonal rhabdomyosarcoma (ERMS) for early childhood, which typically presents in the head, neck and genitourinary (GU) regions; and alveolar (ARMS) for the later childhood and adolescent years and is commonly located in the trunk and extremities.
There are four histologic subtypes: embryonal rhabdomyosarcoma (ERMS), alveolar rhabdomyosarcoma, spindle cell/sclerosing rhabdomyosarcoma and pleomorphic rhabdomyosarcoma. ERMS includes the typical, dense and botryoid patterns of rhabdomyosarcoma.
Dec 18, 2020 · Abstract. Embryonal rhabdomyosarcoma is a malignant tumor deriving from embryonic skeletal muscle cells. It is also known as myosarcoma, malignant rhabdomyoma, rhabdopoietic sarcoma, rhabdosarcoma, embryonal sarcoma, botryoid rhabdomyosarcoma, and sarcoma botryoides. Download chapter PDF.
