title: [Soft tissue chondroma].
abstract: The paper gives a rare case of soft tissue chondroma in a 55-year-old female woman who has unsuccessfully received physiotherapeutic procedures for more than 6 months due to misdiagnosis. The patient detected the tumor herself. Clinical and X-ray diagnostic difficulties are considered. Differential diagnosis was made between synovial chondromatosis and chondrosarcoma. A correct diagnosis could be established only at open tumor biopsy. The neurovascular fascicle, tendons, and an intrinsic group of shoulder muscles could be preserved during radical surgery. The problems in the morphological diagnosis of extraskeletal chondroma are discussed in detail. The results of organ-preserving resection are presented.
