Carcinoid tumors are rare malignant neoplasms of the respiratory system. They belong to neuroendocrine tumors with a low degree of (G1, G2) malignancy. Even less common is the primary multiplicity of these tumors in the trachea and bronchi, which can complicate the only radical, surgical treatment. We present an observation of a 75-year-old patient who was able to diagnose a carcinoid of the cervical trachea and left main bronchus in a timely manner, determine the exact localization and prevalence of the tumor, and successfully conduct surgical treatment in 2 stages.

The described clinical case shows the challenges in the differential diagnosis of primary diffuse large B-cell lymphoma of the lung. It has been shown that the diagnosis can be made only by a morphological examination of a biopsy specimen, and the specimen should be representative and allow for full histological and immunohistochemical testing. A correct diagnostic algorithm, an interdisciplinary approach, the use of new technologies, particularly radiation imaging methods, to reliably determine the primary localization and spread of the pathological process, biopsies for the morphological confirmation shorten the time to diagnosis. A quick diagnosis improves the treatment outcomes and affects the quality of life and life expectancy of patients.

Adrenocortical cancer (ACC) – a neoplasm of the adrenal cortex, which is rare, in 0.02–0.06% of cases. It is characterized by various clinical manifestations in the form of hypercorticism of varying severity and unfavorable prognosis. Typically, a tumor in the form of a node, often with signs of infiltration growth. Some tumors are formed by light and dark cells, there is often significant cellular polymorphism. Malignant tumors of the adrenal cortex have a pronounced tendency to hematogenous metastasis, usually in the lungs, bones and other organs. The article presents a rare clinical case of metastatic lung injury, identified 22 years after the removal of the adrenal malignant tumor (AKP).
