Abstract
BACKGROUND: AIDS-related KS generally involves cutaneous lesions, that slowly progress over months to years. Neither rapidly progressing of KS nor KS complicated with hemophagocytic syndrome (HPS) has rarely been reported. CASE PRESENTATION: We report a rare case of rapid progression of Kaposi's sarcoma complicated with hemophagocytic syndrome in a severely immunosuppressed patient with HIV-infection. The symptoms of this patient were atypical, showing only persistent high fever and rapid progressed to hemophagocytic syndrome. This patient was successfully treated with antiretroviral therapy combined with liposomal doxorubicin. CONCLUSIONS: The condition of the KS patient could deteriorate rapidly over a period of days and even developeded into HPS, which was life-threatening. However, chemotherapy initiated in a timely manner might improve prognosis.
