Laryngeal Kaposi sarcoma: case report and literature review

Laryngeal Kaposi sarcoma: case report and literature review. Problem/Objective: Kaposi sarcoma is the most frequently-occurring neoplasm in AIDS patients. Laryngeal localization is infrequent. We discuss the management options for laryngeal Kaposi sarcoma based on a literature review. Case report: A 42 year old, HIV-positive male receiving HAART therapy presented with mild hoarseness and sore throat. Fiberoptic laryngeal examination identified a small purple lesion in the right ventricular fold. He underwent biopsy under general anaesthesia. The lesion was histologically diagnosed as a Kaposi sarcoma. Systemic treatment was pursued, but 6 weeks later the patient developed severe dysphagia and acute airway obstruction when the lesion became glotto-supraglottic and obstruced the airway. Transoral tumour vaporization with a CO2 laser was performed in the emergency department. Post-operative chemotherapy was administered. Three months later, the patient was completely asymptomatic and the laryngeal examination was normal. Conclusion: Transoral CO2 laser vaporization combined with chemotherapy is a valid option for managing obstructive laryngeal Kaposi sarcoma.
