A malignant sarcoma of soft tissue that arises near but not in a joint, most often in an adolescent or young adult, is typically slowgrowing, and may escapes notice until it causes pain. The diagnosis of this tumor can be suspected by X-ray or imaging, made by biopsy, and confirmed by chromosome studies. Cytogenic studies reveal a translocation between the X chromosome and chromosome 18 in the tumor cells. The most common treatment for the tumor is surgery to remove the entire tumor, nearby muscle, and lymph nodes. Synovial sarcoma tends to recur locally and to involve regional lymph nodes. Distant metastasis occurs in half cases. The well-documented and adequately followed cases are currently lacking and this report described an instance of Synovial sarcoma good result after treatment and review of literature.
