What is a granulomatous lesion of tuberculosis called?

In tuberculosis, the granulomatous lesion is specifically referred to as a tubercle. A tubercle is a small, round inflammatory nodule that forms as part of the body's immune response to the infection caused by the bacterium Mycobacterium tuberculosis. The formation of tubercles is crucial as it represents the body's attempt to wall off the infection and prevent it from spreading.

While a granuloma is a general term for a type of inflammation characterized by the formation of a localized aggregate of macrophages, lymphocytes, and giant cells, not all granulomas are specifically tubercles. A nodule is a more general term that refers to any small mass of tissue, which doesn't have the specific infectious connotation that a tubercle does. An abscess, on the other hand, is a collection of pus that forms due to infection, which differs from the caseous necrosis found in tubercles associated with tuberculosis. Therefore, calling the granulomatous lesion of tuberculosis a tubercle is accurate and reflects its specific association with the disease.
