Abstract

We present the case of a synovial sarcoma five years after primary total hip arthroplasty in a male 65 year-old patient who was surgically treated for left hip pain due to coxarthrosis. A 32 mm uncemented prosthesis with metal-on-polyethylene tribology was placed in the patient. The latter developed synovial sarcoma that caused lung metastasis. The association between total hip arthroplasty and malignancy is discussed, as well as its frequency worldwide.

What is a synovial sarcoma?
A synovial sarcoma (also known as: malignant synovioma[1]) is a rare form of cancer which usually occurs near to the joints of the arm, neck or leg. It is one of the soft tissue sarcomas.
Synovial sarcoma was originally coined early in the 20th century as some thought that the microscopic similarity of some tumors to synovium and its propensity to arise adjacent to joints indicated a synovial origin; however, the actual cells from which the tumour develops are unknown and not necessarily synovial.

If you have had a hip revision, it is likely that during the revision the surgeon had to debride (clean out) the snynovial fluid of metal particles.
