Head and Neck Soft Tissue Sarcoma

Head and Neck Soft Tissue Sarcoma

Module Summary

Sarcomas of the head and neck are rare tumors accounting for approximately 2 percent of all head and neck cancers with approximately 1000 cases diagnosed each year in the United States. Patients that develop sarcomas in this region generally present with a palpable mass, local skin changes, or symptoms arising from site specific complications such as hoarseness, nasal obstruction or cranial nerve deficits. Imaging studies are useful in the in the complete examination of the patient and allow for preoperative staging and planning of reconstruction. Prognostic factors that have been identified include gender, tumor stage, status of surgical margins, histiologic subtype and nodal status. Ideal treatment for these malignancies involves wide margin resections, however due to the proximity to vital structures and the small space in this anatomic region this may not always be possible. The role and benefit of radiotherapy and chemotherapy for treatment of this tumor type is controversial and varies by anatomic site.

Case Studies

  1. A 12-year-old boy presents with chronic nasal obstruction of the right nasal cavity and a mass sensation. Imaging studies and biopsy are consistent with a diagnosis of stage II rhabdomyosarcoma. What considerations must be taken into preoperative planning and prognosis for this patient? What are the possible complications that can arise from treatment?  
  2. A 36-year-old man presents with swelling of the right side of the jaw and pain. Diagnostic studies are consistent with a diagnosis of primary osteosarcoma. What considerations must be taken into preoperative planning for resection and reconstruction of this patient? In what instances would chemotherapy be a viable treatment option for this patient? What are the possible adverse effects related to chemotherapy?
  3. A patient presents with a previously diagnosed chondrosarcoma arising from the laryngeal cartilage. What anatomic considerations must be taken into account for preoperative planning for this patient? What are the potential complications that could arise in resection of this tumor?
