Histiocytoma is an inflammatory pseudotumor usually found in the lung parenchyma or pleura. Endobronchial localisation is rare and can cause atelectasis or air-trapping. Conventional chest X-ray can show the tumor and secondary pulmonary changes. Conventional tomograms and CT can give additional information about tumor extension. However, to make the final diagnosis, biopsy is necessary.
