Abstract
Objectives: Liposarcoma is the second most common sarcoma of the adult life, next to malignant fibrous histiocytoma, accounting for 15% to 18% in different series. Liposarcoma of the head and neck region is rare and comprises only about 3% to 6% of all sarcomas. Liposarcoma of the larynx is even more infrequent and accounts for about 2% of all sarcomas. The aim of this case presentation is to demonstrate one example of the rare entity of laryngeal liposarcomas.
Methods: Case report: A 74-year-old male from Kazakhstan presented in our department with a 3-year history of dysphagia and a feeling of a lump in his throat. He complained of intermittent cough and of vomiting of a pedunculated mass from his pharynx which lolled out of his mouth and could be swallowed again. There was no history of dysphonia, dyspnea, or stridor.
Results: Indirect laryngoscopy showed no tumor. But coughing revealed a tumor arising from the left aryepiglottic fold which could be pulled out of the left corner of the mouth. Direct laryngoscopy and esophagoscopy revealed the lesion to be a large pedunculated polypoidal mass arising from the left aryepiglottic fold with a size of 10 cm in largest diameter. The mass was reddish in color and soft in consistency with an intact overlying mucosa. The tumor was completely surgically excised by means of microlaryngoscopy. Histological examination confirmed the lesion to be a well-differentiated, lipoma-like liposarcoma whose principal treatment is wide excision.
Conclusion: In this case report the presentation, treatment, and prognosis of this rare entity will be discussed.
