Objective: To study the clinical and morphological manifestations of lung sequestration.
Material And Methods: Surgical material (lung tissue) of 18 patients (2017-2021) and 8 archival observations (1972-1994) of confirmed lung sequestration were examined. Histological staining (hematoxylin and eosin, Schiff reagent, Ziehl-Neelsen, picrofuchsin according to Van Gieson) and immunohistochemical reactions with antibodies to SMA, TTF1, CK5/6 (DAKO) were performed.
IgG4-related disease is an immune-mediated disorder with tumor-like multiorgan involvement, elevated serum IgG4 level and specific histopathological appearance (lymphoplasmacytic infiltrate rich in IgG4+ plasma cells and storiform fibrosis). The article presents rare clinical and morphological observations of IgG4-related mastopathy in women with suspected tumor process. A strategy for the treatment of IgG4-related disease should be based on the results of pre-surgery histopathological examination, which may help to avoid unreasonable surgical intervention and choose glucocorticoids or rituximab as the first-line treatment.

The literature describes only single cases of two types of SA in the same patient.
Objective: To identify and determine the clinical and morphological characteristics of combined types of SA in patients with biventricular chronic heart failure (CHF).
