Rhabdomyosarcoma of Stensen's duct in children.

OBJECTIVES: Stensen's duct is a very uncommon location for rhabdomyosarcoma. The purpose of this article was to review the clinical history of 2 patients who had rhabdomyosarcoma of Stensen's duct. METHODS: We reviewed the clinical history, imaging studies, histologic analysis, and treatment of 2 patients with rhabdomyosarcoma of Stensen's duct. RESULTS: An 8-year-old boy (case 1) and a 17-year-old boy (case 2) presented with nonspecific facial swelling. In both patients, imaging studies showed a tumor at Stensen's duct, and biopsy showed embryonal rhabdomyosarcoma. Both patients were treated with preoperative chemotherapy, parotidectomy, and resection of Stensen's duct and postoperative chemotherapy and radiation therapy. Follow-up at 9 years (case 1) and 2 years (case 2) after surgery showed that the patients were free of disease. CONCLUSIONS: Stensen's duct rhabdomyosarcoma is rare and may have a better prognosis than rhabdomyosarcoma in other locations in the head and neck.
