Salivary gland neoplasms represent about 3% of head and neck tumors. The area most affected by tumors is parotid salivary gland (standing for about 80% of all cases). The most common type of the neoplasm is pleomorphic adenoma (which accounts for 80-90% of all diagnoses). One of the rare diagnoses in this region comprises synovial sarcoma, as it mainly occurs in lower extremities. In head and neck region it accounts for about 3% of all diagnoses. About 20 cases have been described in this region, so far. The etiology of the disease remains unknown, but there are reports linking synovial sarcoma with the rearrangement in the gene responsible for chromosomal transcription t(X;18) (p11,q11).
