Pulmonary Talcosis is a rare foreign body granulomatous disease that occurs as a result of exposure to talc either by inhalation of talc particles or via intravascular injection of talc containing medications. Pulmonary Talcosis is often misdiagnosed as pulmonary tuberculosis, atypical mycobacterium infection or sarcoidosis as many of their clinical and radiological findings overlap. We report a case of talcosis mimicking mycobacterial disease which was eventually diagnosed via lung biopsy. A detailed history and high index of suspicion is required for timely diagnosis and appropriate management.

Species of the genus Mycobacterium are capable of inducing cell apoptosis. Infected cells with M. tuberculosis undergo apoptosis through a caspase-dependent pathway. We have previously shown that whole Mycobacterium bovis cells and derived crude protein extracts were able to trigger apoptosis through a caspase independent mechanism. However, the identity of the protein or protein fractions capable of inducing apoptosis has not been determined. In this study, bovine macrophages were incubated in the presence of Mycobacterium tuberculosis recombinant proteins and Mycobacterium bovis protein extracts to identify proteins capable of inducing apoptosis. A subgroup of proteins and protein extracts from strains of the Mycobacterium tuberculosis complex were shown to induce DNA fragmentation in bovine macrophages through a caspase independent pathway. Our findings suggest that bovine macrophages may elicit a different response to mycobacterium infection than that displayed by murine or human cells.
