A gross pathology specimen of caseous pneumonia (казеозная пневмония) - a lung specimen in a glass jar with preservative fluid. The lung tissue is dark brown/reddish-brown, showing a large area of caseous necrosis in the center-upper portion of the specimen. The necrotic focus appears as a pale yellowish-white to creamy cheese-like area surrounded by consolidated dark lung tissue. Add a clear red arrow pointing to the main pathological focus (the caseous necrosis zone) with a label reading "Caseous Necrosis Focus" in bold white text with red background. The label should be clearly visible at the top right of the image.
