OLARTE, Patricia; DUARTE, Ricardo  e  LORA, Alejandro. Retroperitoneal rhabdomyosarcoma in the adult. rev. colomb. cir. [online]. 2012, vol.27, n.3, pp.227-234. ISSN 2011-7582.

Rhabdomyosarcoma is a malignant soft tissue tumor accounting for approximately 4-8% of all solid tumors in children. It generally originates in the head and neck and in the genitourinary system. Retroperitoneal rhabdomyosarcoma has been rarely reported in the literature, and the embryonary rhabdomyosarcoma of omental origin in the adult is even rarer. This soft tissue malignancy is more common in children. The number of cases per million inhabitants was 8.3 (males) and 3.7 (females) in the period between the years 1994 and 2005; most cases are sporadic rhabdomyosarcomas. According to the histologic type, these neoplasms are embryonal, alveolar, and pleomorphic. The embryonal rhabdomyosarcoma is named so for its resemblance to the immature skeletal muscle, and represents 60% of all rhabdomyosarcomas in patients under 20 years of age. The purpose of this article is the review of the scientific literature and the report of a case of retroperitoneal rhabdomyosarcoma in an adult managed at Clínica Universitaria Colombiana, Bogotá, Colombia.
