title: Neuroendocrine carcinoma of the larynx presenting as a primary unknown carcinoma.
abstract: OBJECTIVE
  The case of an 80-year-old man showing a metastatic cervical small cell neuroendocrine carcinoma is presented.
  
  
  RESULTS
  The primary site could not be found at first; it took 8-10 months to detect the primary lesion in the larynx.
  
  
  CONCLUSIONS
  (18)F-deoxyglucose positron emission tomography (FDG-PET) was useful to find the submucosal lesion. Despite surgical treatments and chemotherapy, the patient survived for only 21 months.
