ABSTRACT
The primary rule for making pathological observations and descriptions is “ that the observed facts must be strictly separated from interpretation of these facts”. The gross description begins with the description of the animal. These are Species, breed or type, sex, age, weight and identification marks. If age is not known it should be estimated and facts mentioned. The gross description, whether of an entire organ or structure or of focal pathological changes, is statement of size, shape, colour, consistency, appearance on cut surface and relation to surroundings. The principles of description of microscopic findings are the same as those for gross autopsy description. Facts and not interpretations are given. The descriptions progress from the general to the specific changes noticed. The various terms, pyknosis, necrosis, hydropic degeneration, acanthosis are interpretations. A good pathological description should be neat and efficient. A precise, concise and lucid description gives confidence in the reliability of the observations and the conclusions drawn.
