Infectious granuloma is a medical condition that may refer to several different diseases involving the formation of granulomas (small masses of immune cells) due to an infectious agent. Synonyms for infectious granuloma depend on the type of disease. For example, tuberculosis is a type of infectious granulomatous disease, and synonyms for it may include tuberculosis granuloma or tuberculous granuloma. Similarly, fungal infections such as histoplasmosis or blastomycosis may be referred to as fungal granulomas. Other diseases that may present with infectious granulomas include sarcoidosis, leprosy, and syphilis. It is important to correctly identify the underlying cause of infectious granulomas to determine the appropriate treatment.
