This article reports 30 cases of rhabdomyosarcoma, 25 males and 5 females, male to female ratio of 5:1. The minimum age was 3 months, the maximum was 75 years old, and the average age was 25.7 years; the peak incidence was from 3 months to 9 years old (11 cases in total, accounting for 36.7%). Polymorphic rhabdomyosarcoma is older, and other ages are lower. This group of cases occurred in 11 cases of head and neck, 8 cases of lower extremities, 6 cases of genitourinary system, 3 cases of trunk, 2 cases of abdominal cavity. Most of the growth in the head and neck was embryonic (7 cases), followed by alveolar (3 cases), and only 1 case of polymorphism. In the lower limbs, pleomorphism was dominant (5 cases), embryonal in 2 cases, and alveolar in 1 case. Growth in the urinary system was mainly embryonal and grape-shaped rhabdomyosarcoma (3 cases each). Visit
