Liposarcoma of the Larynx

OBJECTIVES: The objective was to review the presentation, diagnosis, treatment, and prognosis of patients with laryngeal liposarcoma (LLS). A case is reported, and a retrospective review of the English-language literature is presented. METHODS: All published cases of LLS with adequate histopathologic documentation and clinical information were included for review. RESULTS: Thirty cases of LLS have been reported. A majority of these patients are men between 40 and 70 years of age. The most common location of the tumor is the supraglottis, and the presenting complaints are similar to those of other laryngeal neoplasms. Although these neoplasms recur often and can cause significant morbidity, they are typically of low grade and rarely metastasize. The outcomes of this disease are generally good when it is treated with wide surgical excision. CONCLUSIONS: Cases of LLS are extremely rare. Because the histologic changes are frequently subtle, LLS can be easily mistaken for a benign tumor. As a result, the diagnosis requires a high index of suspicion and diligence in examining biopsy specimens. Computed tomography and magnetic resonance imaging can assist in the diagnosis and surgical approach. Genetic and immunostaining analysis techniques may also prove to have valuable prognostic, diagnostic, and therapeutic implications for this disease. Wide surgical excision is the mainstay of treatment. The use of radiotherapy and chemotherapy in treating this cancer remains experimental, but might be considered on a case-to-case basis for palliation or to treat aggressive variants of the disease.
