Abstract

Kaposi's sarcoma (KS) is an angiogenic tumor. KS lesions frequently develop in the skin and oral cavity mucosa in the head and neck regions, and pure laryngeal localization is extremely rare. We reported a 64-year-old male patient without HIV, HBV, and HCV positivity presented with a hemangiomatous lesion detected incidentally in the right vocal cord. Biopsy was taken for histopathological and immunohistochemical evaluation. Examination revealed that spindle cells were of vascular origin and expressed HHV-8, a specific marker associated with Kaposi's sarcoma-associated herpesvirus. Positron emission tomography-computed tomography (PET/CT) demonstrated an increased fluorodeoxyglucose (FDG) uptake in the vocal cord. The patient was treated with a 30 Gy volumetric arc plan. Disease-free follow-up continues in the first year after low-dose definitive RT. This is the first case report of KS in the vocal cord in which the most detailed data about RT were shared.
