Abstract

Tuberculosis (TB) and malignancy are among the most important current global health problems. Many authors suggest that their coexistence is a chance association owing to their high prevalence. There is, however, enough evidence that one condition may predispose the other. In our retrospective report of two cases, TB in draining lymph nodes was discovered incidentally on histopathology, following surgical resection for malignancy. The possibility of coexistent lesions, especially in regions endemic for TB, mandate a detailed histopathological examination to prevent the chances of diagnostic failure and thus therapeutic error.
