Its existence was controversial for many years, until modern techniques of pathomorphological diagnosis approved it as a separate entity of lung disease. It manifests in the form of well limited nodules localized in the lungs, which are mostly identified accidentally. Clinical symptoms are rare and nonspecific; the disease usually occupies only one lung. Pathomorphological diagnosis requires immunohistochemical designation of expressions of numerous antigens in order to exclude malignant lymphoma of the lungs. Surgical resection is used in cases of larger nodules; the smaller ones require periodic observation, and the prognosis is good. The authors describe the case of 65-year-old woman with pulmonary nodules which were detected accidentally in the right lung. The patient was qualified for right-sided videothoracoscopy and removal of the lung nodule. In classic HE staining of the histological material, the presence of lymphoid infiltration of the lungs was revealed, which formed lymph follicles with reactive germinal centres. In order to differenti...
