Kaposi's sarcoma of the larynx: An unusual presentation. Case report

Kaposi's sarcoma is an uncommon angioproliferative tumor in non-immunocompromised patients. It is located mainly on the skin, although, in some patients, it can present in solid organs and viscera. The involvement of the larynx is exceptional and when present, it is associated with severe states of immune suppression. We present the case of a non-immunocompromised male patient without a history of human immunodeficiency virus, who consults for a two-month history of hemoptysis, globus pharyngeus, and progressive dysphonia. On physical examination and flexible fiberoptic nasolaryngoscopy a mass is seen in the posterior supraglottis, lobulated and violet in color, obstructing approximately 90% of the airway at that level. An excisional biopsy was performed by transoral laser CO2 microsurgery, and pathology reported Kaposi's sarcoma. Postoperative follow-up does not show tumor recurrence.
