title: An extremely rare case of large Delphian node metastasis preceding primary laryngeal cancer.
abstract: OBJECTIVE
  To present an extremely rare case of large Delphian node metastasis preceding primary laryngeal cancer.
  
  
  METHODS
  A 74-year-old male who noted a mass on the lower anterior neck and consulted our department immediately. The mass rapidly grew to 6cm from 2cm in diameter within 2 months after the initial presentation.
  
  
  RESULTS
  Fiberoptic laryngoscopy was unremarkable. Surgical excision of the lesion showed well differentiated squamous cell carcinoma with invasion into the surrounding tissues. Postoperative radiotherapy was added. During follow-up after those treatments, thickening of the right vocal cord was observed, which gradually became more apparent. Total laryngectomy was performed 13 months after the initial operation.
  
  
  CONCLUSIONS
  Delphian node metastasis is included in the differential diagnosis in a case of rapidly increasing mass in the anterior neck.
