Synovial sarcoma presenting as a parotid mass: Case report and review of literature

Abstract

Review of the literature suggests an aggressive long-term outcome for synovial sarcoma and advocates early diagnosis and radical surgical excision for a favorable prognosis.

Clinicopathologic factors and adjuvant treatment effects on survival in adult head and neck synovial cell sarcoma

“…Overall 5‐year survival rates of head and neck synovial cell sarcoma range between 40% and 50% . Two‐year recurrence rates after successful surgery and radiation have been widely reported at 50% …”

“…2,28,29 Two-year recurrence rates after successful surgery and radiation have been widely reported at 50%. 19,30 All of our patients initially treated at The Mayo Clinic underwent surgical resection of the primary tumor as initial management. Postoperative adjuvant therapy was heterogenous among our patient population with most patients receiving radiation with or without chemotherapy.…”

Excellente réponse à la radiothérapie externe d’un synovialosarcome primitif de la glande parotide

“…La région de la tête et du cou est le deuxième site atteint représentant 5% à 10% des cas. Cette tumeur survient très rarement et pose le diagnostic différentiel avec l’envahissement de la glande parotide par un synovialosarcome d’une structure de voisinage, avec le carcinome myoépithélial et avec d’autres tumeurs primitives mésenchymateuses [2]. Le traitement de base est l’exérèse chirurgicale large chaque fois que celle-ci est possible, associée à une radiothérapie externe, notre cas s’ajoute pour confirmer l’efficacité de ce traitement combiné.…”

Exclusive periductal/pericystic growth pattern in a case of long‐standing monophasic synovial sarcoma of the parotid gland

“…Our review of the literature identified only seven biopsy‐proven cases of SS occurring in the parotid gland . There were two males (29%) and five females (71%) aged 15–72 years (median value 35 years).…”

“…Our review of the literature identified only seven biopsy-proven cases of SS occurring in the parotid gland. [2][3][4][5][6][7][8] There were two males (29%) and five females (71%) aged 15-72 years (median value 35 years). Symptoms had lasted for 2-120 months (median value 24 months) before diagnosis, with the main signs/complaints being local swelling (seven cases, 100%), facial pain (two cases, 29%), headaches (1996).…”
