Tuberculosis is an infectious disease and can be cured. Sarcoidosis is a non-infectious immune-mediated disease and it cannot be cured, its an auto-immune disease, for some it goes away on its own but for others they have it for life and its treated by suppressing the immune system.

The only similarity is they are granulomatous diseases but they cause different types of granuloma, so they are distinctly different.

I had been diagnosed of Tuberculosis but confused with Sarcoidosis. Can you suggest the categorical difference between the two diseases.
