title: Classic Kaposi's sarcoma in Han Chinese and useful tools for differential diagnosis.
abstract: Kaposi's sarcoma (KS) is a common AIDS-related malignant neoplasm in the head and neck region, especially in the oral cavity, but is rarely described in the HIV-negative and non-immunosuppressed individual. Our case is of interest, because it is the first case in which manifestation of the KS occurred in the face and head areas in a patient with a Han ethnic background who had an adequate immune system. The lesions were diagnosed as angiosarcomas twice. The clinical presentation, therapeutic options, and tools for differentiating Kaposi sarcoma from other vascular and nonvascular spindle cell lesions are presented, and the relevant literature is reviewed.
