Orificial tuberculosis and Kaposi's sarcoma in an HIV-negative individual.

Orificial tuberculosis is a rare form of cutaneous tuberculosis. It happens mainly in immunocompromised patients and is characterized by rapidly ulcerating papules in the orifices, including oropharynx or anus, due to autoinoculation of internal tuberculosis. It is a symptom of advanced underlying disease. Kaposi's sarcoma occurs more frequently with the increase of HIV-infected patients. We report on an HIV-negative individual who developed rapid-deteriorating orificial tuberculosis concomitant with Kaposi's sarcoma and had a fatal outcome.
