title: Ectopic production of beta-HCG by a maxillary squamous cell carcinoma.
abstract: BACKGROUND
  Paraneoplastic syndromes of the head and neck are rare. Hypercalcemia and leukocytosis have been described. The literature was reviewed, and a case of a squamous cell carcinoma of the maxilla producing beta human chorionic gonadotropin (beta-HCG) is presented.
  
  
  METHODS
  A 47-year-old white man with a T4N1M0 squamous cell carcinoma of the left maxilla was treated with a maxillectomy and neck dissection for an N1 positive neck. After completing his planned radiotherapy, he developed distant metastases, which included an axillary node that stained positive for human beta-HCG.
  
  
  RESULTS
  Retrospective review of the primary specimen showed beta-HCG positivity in an anaplastic component of the tumor along with vascular invasion.
  
  
  CONCLUSIONS
  The first case in the literature of a paraneoplastic syndrome with beta-HCG production in association with squamous cell carcinoma of the maxilla is presented. This case history fits the aggressive nature of beta HCG producing tumors elsewhere in the body.
