A gross pathology specimen of a lung with caseous pneumonia (казеозная пневмония) in a preservation jar. The specimen shows a dark brown consolidated lung lobe. On the image, there is a clearly visible area of caseous necrosis - a pale yellowish-white, cheese-like (caseous) necrotic focus in the central/upper portion of the lung parenchyma. Add a red arrow pointing to this main pathological focus with a label that reads "Caseous Necrosis Focus" in bold red text. The label should be clean and professional, placed outside the specimen area. Background matches the original: glass jar with amber/yellow preservation fluid, white label at top reading "КАЗЕОЗНАЯ ПНЕВМОНИЯ".
