What is a granuloma histology?
A granuloma is a type of chronic inflammation that forms in an attempt to contain and remove a harmful agent from the body. Granulomas are made up of specialized immune cells including lymphocytes, histiocytes, and multi-nucleated giant cells.
How do you identify a granuloma?
A granuloma can only be diagnosed when a pathologist observes this type of inflammation under the microscope. If a foreign body or a parasite is not observed inside the granuloma, stains for acid-fast bacilli and fungi are ordered since mycobacteria and fungi are frequently the cause of this type of inflammation.
What is a distinguishing feature of granulomatous inflammation?
Abstract. The granulomatous inflammatory response is a special type of chronic inflammation characterised by often focal collections of macrophages, epithelioid cells and multinucleated giant cells.
What are the components of granuloma?
Granulomas. Granulomas, consisting of aggregates of macrophages, often including multinucleated giant cells and “epithelioid” macrophages together with variable numbers of lymphocytes, are a pathologic hallmark of tuberculosis.
What is the significance of a granuloma?
Granulomas seem to be a defensive mechanism that triggers the body to “wall off” foreign invaders such as bacteria or fungi to keep them from spreading. Common causes include an inflammatory condition called sarcoidosis and infections such as histoplasmosis or tuberculosis.
How is a granuloma formed?
Granuloma formation is com- prised of four main steps: (1) the triggering of T cells by antigen- presenting cells, represented by alveolar macrophages and dendritic cells; (2) the release of cytokines and chemokines by macrophages, activated lymphocytes, dendritic cells, and poly- morphonuclear cells.
How do I choose the best granuloma annulare treatment?
One option for granuloma annulare treatment cryotherapy, which involves applying liquid nitrogen to any bumps on the skin to freeze them off. Drinking lots of water may help treat granuloma annulare. Corticosteroids applied as a topical ointment are the usually the first choice of treatment by dermatologists for granuloma annulare.
What drugs cause granuloma annulare?

What does granuloma, giant cell mean?
Granuloma, Giant Cell. A non-neoplastic inflammatory lesion, usually of the jaw or gingiva, containing large, multinucleated cells. It includes reparative giant cell granuloma. Peripheral giant cell granuloma refers to the gingiva (giant cell epulis); central refers to the jaw.
