Rhabdomyosarcoma (RMS) is usually considered a childhood soft tissue tumour. It normally arises within extremities, head and neck region and the genitourinary system. Common sites in the genitourinary tract include the urinary bladder, prostate and paratesticular soft tissues. It can arise at unusual sites but very rarely. RMS is more common in males as compared to females and two-thirds of the cases are diagnosed in children aged 6 years or younger with a smaller incidence peak in mid-adolescence. The annual incidence is four to seven per million children of 20 years or younger. Approximately 350 cases are diagnosed per year in the USA. Unfortunately, statistics of RMS are not known for Pakistan.
横纹肌肉瘤（RMS）通常被认为是一种儿童软组织肿瘤。它通常发生在四肢、头颈部区域以及泌尿生殖系统。泌尿生殖道的常见部位包括膀胱、前列腺和睾丸旁软组织。它也可能发生在不常见的部位，但极为罕见。与女性相比，RMS在男性中更为常见，三分之二的病例在6岁及以下儿童中被诊断出来，在青春期中期有一个较小的发病高峰。20岁及以下儿童的年发病率为每百万中有4至7例。在美国，每年约有350例病例被诊断出来。遗憾的是，巴基斯坦尚无RMS的统计数据。
