Abstract

<p>Background. Most long-standing foreign bodies (FBs) in the airway are asymptomatic, but some can become symptomatic. Case. We encountered a 75-year-old man. Nine years earlier, chest X-ray at a medical examination had revealed a FB suspected of being metallic in the right lower zone. However, he wished the FB to be observed, as it was asymptomatic. Two years ago, chest CT revealed that the FB was surrounded by a shadow, and a small amount of right pleural effusion was noted. Because he was still asymptomatic, we continued to observe it, until it ultimately began to induce cough as a symptom. He was therefore referred to our hospital. Bronchoscopy revealed granulomatous and friable tissue in the right B10, but the FB could not be identified. Right lower lobectomy was performed to remove the FB as well as the surrounding shadow. A pathological examination revealed that lung tissue peripheral from the FB had a high degree of fibrosis and accumulation of plasmacytes and lymphocytes, which indicated obstructive pneumonia accompanied by fibrosis. Conclusion. If a long-standing FB in the airway with surrounding shadow and atelectasis is not differentiated from malignant disease or is difficult to remove and causes obstructive pneumonia, surgical resection needs to be considered.</p>
