title: Lipoma and liposarcoma of the larynx: case reports and literature review.
abstract: OBJECTIVE
  Two cases of laryngeal lipomatous tumors are presented. Their diagnoses and management are discussed and contrasted.
  
  
  METHODS
  Case report and literature review.
  
  
  RESULTS
  Patient 1 is a 58 year old male presenting with five years of progressive shortness of breath, dysphagia, and globus sensation. Clinical exam and imaging study showed a 3.5 cm hypodense laryngeal mass, and he underwent transoral robotic-assisted surgery for complete excision. Final pathology revealed a well-differentiated liposarcoma. Patient 2 is a 79 year old female presenting with one year of non-progressive hoarseness and globus sensation. Clinical examination and imaging study revealed a 1.8 cm hypodense laryngeal mass. Transoral endoscopic complete excision of the submucosal mass was performed. Final pathology revealed benign spindle-cell lipoma.
  
  
  CONCLUSIONS
  Liposarcoma and lipoma may present with similar symptomatology, clinical, and imaging findings. Pathology evaluation is of utmost importance for definitive diagnosis. Therefore, diagnosis and treatment of laryngeal lipomatous lesions are best accomplished with complete excision of the mass.
