The case of death of a 74-year-old man with bilateral multisegmental pneumonia with progressive pulmonary-cardiac insufficiency is presented. The pathological anatomical examination verified rectal cancer, as well as extensive lesions of visceral and parietal lymph nodes of the small pelvis, lymph nodes along the main trunks of the inferior, superior mesenteric arteries, in peri-aortic and para-aortic areas behind the peritoneum along the spine along the course of the abdominal aorta, further in the lower and upper tracheobronchial localisations (a total of 25 lymph nodes) and lower lobes of the lungs. When comparing the structural characteristics of rectal carcinoma and tumour growths in lymph nodes and lungs, phenotypic morphological discordance was found, which required additional immunohistochemical study of the material (PAN-CK, CDX-2, CD20). When comparing the results of all the morphological studies performed, the evidence base was obtained to interpret the changes in groups of lymph nodes and lung tissue as a metastatic process of intestinal cell carcinoma.
