Kaposi's sarcoma of the larynx

Abstract

Kaposi's sarcoma (KS) is a neoplastic vascular disorder, classically arising in the skin of the lower extremities. As a consequence of the acquired immunodeficiency syndrome (AIDS) epidemic, an increasing number of patients have been found to have KS. In AIDS patients, KS appears to exhibit a more diffuse nature and frequently affects the head and neck. Mucosal lesions are most often seen, commonly involving the oral cavity. Only rare cases of laryngeal involvement have been recorded in the literature. We report 2 cases of KS of the supraglottic larynx. Our first patient, an elderly man of Mediterranean descent, complained of voice change and throat discomfort. Endoscopy with biopsy for diagnosis allowed conservative treatment with chemotherapy. Our second patient was a younger man with AIDS who presented with symptoms of airway obstruction. Management with carbon dioxide laser epiglottectomy was successful in relieving that patient's symptoms. Although rare, KS may present in both healthy and immunocompromised patients, and must be considered in the differential diagnosis of all violaceous lesions of the larynx.
