A 42-year-old patient suffered for many years from chronic bronchitis and chronic right-side pneumonia. A tumour obturating the right main bronchus was diagnosed tomographically and fiber bronchoscopically. Ovoid tumour, 2 x 3 cm in size, originating from the distal bronchus, was removed during the operation (bronchotomy). Histologically, an encapsulated tumour was found consisting of lipocytes with rare bronchial glands and narrow spaces and channels lined with one layer of the respiratory epithelium. Bone inclusions attributed to metaplasia were found in the capsule.
