A case of the patient with Hodgkin's lung lymphoma, who ten years ago was treated because of having Hodgkin's lymphoma of the mediastinum and neck, is reported in this paper. This time, the patient has been admitted to the hospital due to the pulmonary infiltration in the left upper lobe. As the etiology of the pulmonary infiltration could not be established by a routine diagnostic procedure (sputum cytology, catheter bronchial aspirate smears, bronchial brushing, excision of the bronchial mucosa, transtracheal and transbronchial aspiration), the transthoracic fine needle aspiration was performed to confirm the diagnosis. Cytologically, beside erythrocytes, the cells of the bronchial epithelium, eosinophilic granulocytes and lymphocytes, the cells of the Reed-Sternberg cell type were found in the transthoracic aspirate smears too.
