Caseous is an adjective denoting a cheesy, moldy, or cheesy-textured appearance or composition; in pathology, it describes a cheese-like, friable substance seen in caseating necrosis. It conveys a form that resembles milk cheese in texture or consistency and is used to describe such material or lesions, especially in tuberculous contexts. The term is precise, technical, and rarely used outside medical literature unless describing appearance.
