Intestinal Intussusception by Monophasic Synovial Sarcoma: Case Report and Literature Review.

INTRODUCTION Synovial sarcomas are rare malignant tumors of soft tissues, arising mainly from periarticular structures. Gastrointestinal localizations are unusual presentation of these rare sarcomas. METHODS We present the case of a 56- years old man with monophasic synovial sarcoma, arising primarily from the ileum, and causing intussusception. A review of the literature was conducted to gather information about this rare sarcoma. RESULTS We found that the criteria normally used to determine the prognosis in patients with monophasic synovial sarcoma of soft tissue are poorly applicable for gastrointestinal localizations. CONCLUSIONS A better characterization of these tumors could identify them as a distinct entity, compared with monophasic synovial sarcomas of soft tissues.
