Kaposi's sarcoma is a lympho-angioproliferative disease that primarily affects the skin and subcutaneous tissues. Most importantly, Kaposi’s sarcoma occurs in the immunocompromised, especially AIDS patients and organ transplant recipients being treated with immunosuppressants. The occurrence of classic Kaposi’s sarcoma after the diagnosis of any primary solid tumor has rarely been reported. We experienced a 70-year-old man, who had received surgery and chemoradiotherapy for the treatment of primary gallbladder cancer, that developed multiple tender deep purple papules on his trunk, back and feet which were proven to be pathologic symptoms of Kaposi’s sarcoma.
