Orofacial rhabdomyosarcoma in neonates and young children: a review of literature and management of four cases.
Rhabdomyosarcoma (RMS) is an aggressive malignant skeletal muscle neoplasm arising from embryonal mesenchyme. It accounts for over 50% of all pediatric soft tissue sarcomas. The head and neck region is the most common site for this tumor in children. Neonatal presentation of this tumor is rare. We present the management of one neonatal case and three additional cases of orofacial RMS in children under the age of 7 years. All four patients were seen in the department of oral and maxillofacial surgery at Children's Hospital and Regional Medical Center (CHRMC) in Seattle between 1992-2000. Three of the four cases were alveolar RMS and one was botryoid sub-type of embryonal RMS. Three patients were treated with a combination of surgery, chemotherapy and radiation, while the patient with botryoid RMS was treated with surgery and chemotherapy only. The patient with congenital RMS died at 2.5 years of age due to recurrent metastatic disease. The other three patients are alive without evidence of recurrent with a mean follow up was 5.5 years (range 2.5-8.5 years). We discuss the current management, diagnosis, biological behavior, histopathology, prognosis and survival of head and neck RMS in neonates and young children.
