mast cell
This term is a specialized biological designation used primarily in medical, immunological, and histological contexts. It describes a specific effector cell of the innate immune system. Because it is a technical term, it is rarely found in casual conversation and is typically used in clinical reports or scientific literature to explain the mechanism of hypersensitivity.
In a clinical setting, the term is frequently associated with the process of degranulation, where the cell releases inflammatory mediators. It is distinct from basophils, although both share similar functions; the primary difference lies in their location and origin, with mast cells residing in tissues while basophils circulate in the blood.

Examples
Degranulation occurs when a mast cell is triggered by an allergen.
