Granuloma

In medicine (anatomical pathology), a granuloma is a group of epithelioid macrophages surrounded by a lymphocyte cuff. Granulomas are small nodules that are seen in a variety of diseases such as Crohn's disease, tuberculosis, sarcoidosis, berylliosis and syphilis. It is also a feature of Wegener's granulomatosis and Churg-Strauss syndrome, two related autoimmune disorders. Important aspects of granulomas are:

• Whether they are caseating or not. Caseation (literally: turning to cheese) is a form of necrosis at the centre of a granuloma and is a feature of the granulomas of tuberculosis.
• More to be added
