title: [Ultrasound tomography in diagnosis of malignant soft tissue tumors in children].
abstract: Ultrasound findings of 50 children with soft tissue sarcomas of the trunk and limbs were analyzed. There was a high proportion of diagnostic errors (62%), which resulted in the choice of adequate therapeutical measures at early stages of therapy and in advanced disease. The reasons of the errors were as follows: nonspecificity of the first clinical manifestations of soft tissue sarcomas; ignorance of instrumental studies that establishes a diagnosis in time; outpatient physicians' unconcern of cancer, misunderstanding of the nontumor nature of disease; no scientifically grounded algorithm of studies. Echographic signs that characterize malignancy, their changes over a therapy, ultrasound pattern due to posttherapeutical changes are considered.
