AGGRESSIVE RHABDOID TUMOR IN THE RIGHT LUNG: A CASE REPORT.

Rhabdoid tumor is a rare and aggressive neoplasm that usually occurs in children and is often localized in the central nervous system and kidneys, but can be found in many other sites. In our case report, we describe a tumor that was found on computed tomography in the thoracic region of a 62-year-old male and was successfully surgically resected. The images and descriptions of our findings and the results of the additional immunohistochemical studies allow us to make the final diagnosis.

Morphological and functional features of the colonic mucus barrier in patients with symptomatic uncomplicated diverticular disease and acute uncomplicated diverticulitis.

Objective: Aim: The purpose was to identify the morphological and functional features of the colonic mucus barrier in patients with symptomatic uncomplicated diverticular disease and acute uncomplicated diverticulitis.

Patients And Methods: Materials and Methods: In the research, three groups were formed. Group 1 included fragments of the mucous membrane of the large intestine, which were collected from 12 people during autopsies.

Management of granulomatosis with polyangiitis complicated by intestinal perforation and pancytopenia: a case report and literature review.

Granulomatosis with polyangiitis is a systemic vasculitis. While the classic triad typically comprises otorhinolaryngologic, pulmonary, and renal manifestations, it is essential to recognize that granulomatosis with polyangiitis can affect any organ. Furthermore, reports have documented less common sites of involvement, such as the gastrointestinal tract.

MORPHOLOGICAL FEATURES OF MAXILLARY SINUS CYSTS BASED ON THE STUDY OF PARTICULAR HISTOCHEMICAL AND IMMUNOHISTOCHEMICAL FACTORS OF INFLAMMATION.

Objective: The aim: To study the morphological structure and immunohistochemical markers of inflammatory cells in the maxillary sinus cyst wall.

Patients And Methods: Materials and methods: Biopsy samples of maxillary sinus cysts of 92 operated patients aged 18 to 74 years were studied. We used standard staining with hematoxylin and eosin, PAS reaction, and immunohistochemical analysis with monoclonal antibodies to CD68 (macrophages) and CD3 (T- lymphocytes) to determine morphological features and severity of inflammation and PanCK AE1/AE2 antibodies to identify epithelium state.

Lung Expression of Macrophage Markers CD68 and CD163, Angiotensin Converting Enzyme 2 (ACE2), and Caspase-3 in COVID-19.

The coronavirus (SARS-CoV-2) damages all systems and organs. Yet, to a greater extent, the lungs are particularly involved, due to the formation of diffuse exudative inflammation in the form of acute respiratory distress syndrome (ARDS) with next progression to pulmonary fibrosis. SARS-associated lung damage is accompanied by the pronounced activation of mononuclear cells, damage of the alveoli and microvessels, and the development of organized pneumonia.
