title: [Analysis of clinical manifestations of pharyngeal and laryngeal amyloidosis].
abstract: OBJECTIVE
  To study the clinical manifestations of pharyngeal and laryngeal amyloidosis.
  
  
  METHODS
  Retrospective analysis of the clinical data of the inpatients with systemic and local amyloidosis.
  
  
  RESULTS
  Of the 25 cases, sex ratio was 21:4, and average age was 48 years. Seventeen cases were systemic, of which 7 patients died in 2 years since diagnoses were made. One case was local bronchial amyloidosis. Seven cases were local primary pharyngeal and laryngeal amyloidosis and no affirmative death report was recorded since diagnoses were made.
  
  
  CONCLUSIONS
  Amyloidosis occurs more likely in male and middle- and old-aged patients. Pharyngeal and laryngeal local primary amyloidosis have relatively better prognosis than that of systemic amyloidosis. Follow-up is important because local recurrence may be happened.
