[Clinical manifestations and diagnosis of rhabdomyosarcoma of childhood at different sites].
Soft tissue sarcomas occupy the fourth place in the pattern of malignant neoplasms in children. Rhabdomyosarcoma (RMS) is more common (about 38%) among various morphological variants of soft tissue sarcomas. The specific features of RMS sites (the head and neck, torso and extremities, viscera, small pelvis, chest, and abdomen, genitalia) determine a diversity of clinical manifestations, as well as diagnostic problems. There are a great deal of diagnostic errors that are as high as 85%. Diagnosing RMS in children should be comprehensive and based on clinical, instrumental, laboratory, X-ray, radionuclide, ultrasonic, and morphological findings.
