Abstract

We herein report a case of pulmonary hyalinizing granuloma (PHG), which is a rare pulmonary mass. A 69-year-old man with no symptoms presented to our hospital because of the appearance of an abnormal shadow on chest X-ray. Computed tomography revealed a right middle-lobe mass with spicula and infiltration into the upper lobe. Since a bronchofiberscopic examination showed no malignant cells in the specimen, the patient underwent thoracoscopic surgery, which revealed PHG. Spiculation and interlobar infiltration, which comprise the characteristic features of primary lung cancer, are uncommon presentations of this rare entity.
