Simultaneous occurrence of pulmonary tuberculosis and carcinomatous lymphangitis.

Tuberculosis is an important cause of mortality due to its high prevalence, considering that one third of the worlds population is infected with the tuberculosis bacillus. We report the first case of carcinomatous lymphangitis associated with active pulmonary tuberculosis. Carcinomatous lymphangitis is a rare event that may be confounded with tuberculosis because of its radiographic and clinical characteristics.
