Cytological examination of the material from the bronchopulmonary system is a highly effective method of diagnosing lung cancer. Cytomorphological criteria for various types of lung tumors, including adenocarcinomas, are well known and described in detail in the literature. However, in some cases, cytologists face difficulties in the differential diagnosis of various types and subtypes of malignant lung lesions, which determines the continuing interest in studying their cytomorphological features. The article presents a clinical and morphological case of lung adenocarcinoma, shows the high efficiency of the traditional (classical) cytological method in its diagnosis, which complements the literature data.

INTRODUCTION

Lung cancer (LC) occupies a leading place in the structure of the incidence of malignant neoplasms and a leading place in the structure of mortality among cancer patients. Cytological examination of lung material is a highly informative, accessible and minimally invasive method of diagnosing LC.

DISCUSSION

The article presents a clinical and morphological case of lung adenocarcinoma in a 62-year-old man. To assess the lesion, a comprehensive diagnosis was carried out using a combined cytological method of examining sputum samples, taking into account clinical and anamnestic data and the results of imaging studies. The data obtained were correlated with the results of histological and immunohistochemical studies.

CONCLUSION

An integrated approach based on the analysis of the morphological features of the cellular material, clinical and anamnestic data, and the results of immunochemical research allows to increase the value of cytological examination of sputum. The results of the combined cytological examination correlate with the data of histological and immunohistochemical studies.
