The diagnostic challenge of pulmonary Kaposi's sarcoma with pulmonary tuberculosis in a renal transplant recipient: a case report.

We report a case of a 39-year-old, HIV-negative, post renal transplant patient who developed mucocutaneous Kaposi's sarcoma with lung parenchymal involvement and concurrently culture proven pulmonary tuberculosis. To the best of our knowledge, this is the first case report of this combination, which presented with cavitating lung nodules and responded well to withdrawal of immunosuppressive drugs beside antituberculous treatment.
