Pulmonary Pathology, Set 1

For each of the following patients, select the most likely pathologic finding:

1. A 23-year-old healthy woman experiences fever, cough, and dyspnea while staying at her sister's house for a few days, but she ceases to have these problems when she returns to her own home. She experiences a similar episode on a visit 6 months later. A chest x-ray shows no abnormal findings:

2. A 62-year-old man has had a cough for several months. He is a smoker. Recently, he had hemoptysis. A chest radiograph reveals a right hilar 6 cm mass. A chest CT scan confirms the presence of the mass, but there are infiltrates distal to the mass. On bronchoscopy, there is obstruction of a right upper lobe bronchus, and a biopsy reveals squamous cell carcinoma:

3. During the week following intubation and use of 100% inspired oxygen, a 31-year-old man requires increasing ventilatory pressures to maintain oxygenation:

4. A 42-year-old man has a chronic abscess of the right middle lobe several months following orthotopic cardiac transpslantation:

5. A 56-year-old man has had increasing dyspnea for several years. A chest radiograph reveals marked interstitial fibrosis. At autopsy both lungs have numerous very firm 0.5 to 1.0 cm fibrous pulmonary nodules. By light microscopy, the nodules contain birefringent crystals:
