title: Laryngeal papillary carcinoma with unexpected evolution: case report.
abstract: BACKGROUND
  According to the literature, laryngeal papillary carcinoma is rare and has a benign prognosis.
  
  
  METHODS
  In this report we present a surprising case with nodal metastasis at the time of diagnosis. Computed tomography showed infiltration of the lesion and metastatic lymph nodes. The resected specimen was submitted to histopathological study that confirmed the diagnosis of papillary squamous cell carcinoma.
