ExplanationIn the 7th edition of Robbins it was clearly stated that…“Caseous necrosis, a distinctive form of coagulative necrosis, is encountered most often in foci of tuberculous infection. The term caseous is derived from the cheesy white gross appearance of the area of necrosis.”
Regarding the option gangrene, it is not specified the type of gangrene and therefore, we go with the better option as tuberculosis in the given question. Moreover, according to Robbins, gangrenous necrosis is not a specific pattern of necrosis
but is a term used in clinical practice.
