Primary intraosseous Kaposi’s sarcoma of the maxilla in AIDS: a case report

In China, Kaposi’s sarcoma (KS) is very rare. However, KS does occur as one of the complications in patients with acquired immunodeficiency syndrome (AIDS). Usually AIDS-related KS involves the lymph nodes, the skin and gastrointestinal tract. Intraosseous KS have been reported but it is very rare. We report a case of primary intraosseous KS of the maxilla in an AIDS patient, proven by pathology findings and showed multiple metastasis by positron emission tomography and computed tomography (PET/CT). To our knowledge, this is the first report of primary intraosseous KS of the maxilla in an AIDS patient in China.
