Final answer:
A consequence of chronic inflammation for the host is the formation of a granuloma, which occurs when immune cells encapsulate persistent pathogens or irritants.
Step-by-step explanation:
A consequence of chronic inflammation for the host is the formation of a granuloma. Chronic inflammation can lead to the accumulation of immune cells which aim to encapsulate and contain the persistent irritant or pathogen. This aggregation forms a granuloma, which is a structured collection of immune cells, like macrophages, that often encapsulate non-degradable pathogens or foreign materials. Granulomas serve to wall off the irritants and prevent their spread. They are a hallmark of various chronic inflammatory diseases, such as tuberculosis, sarcoidosis, and chronic granulomatous disease.
In comparison, a boil or furuncle is a local infection of a hair follicle or oil gland. When multiple boils coalesce and form a deeper lesion, it is known as a carbuncle. An abscess, on the other hand, is a collection of pus that has built up within the tissue of the body. A cyst is a pathological epithelial lined cavity that fills with fluid or soft material, which is not necessarily caused by infection but can be a result of chronic inflammation.
