The patient was a 16 year old girl who developed a nonproductive cough and intermittent wheezing in
the absence of any viral illness. She failed to respond to antibiotics and bronchodilators and
progressively worsened over three months with severe exertional dyspnea. Pulmonary function tests showed
severe airflow obstruction with no response to bronchodilators:
|PFT ||Initial visit ||1 month ||3 months ||1 year|
|FEV1/FVC ||32% ||37% ||36% ||39%|
She failed to respond to B-agonist inhalation and oral and intravenous theophylline and prednisone.
No evidence of alpha-1-antitrypsin disease, cystic fibrosis or aspiration was found on clinical,
radiologic or serologic evaluations. She had a weakly positive rheumatoid factor, but other work-up for
collagen vascular disease was negative. A clinical diagnosis of bronchiolitis obliterans was made. She
underwent a left thoracotomy and a diagnosis of "consistent with bronchiolitis obliterans" was made. She
required intubation and mechanical ventilation on several occasions and was eventually transferred to The
Methodist Hospital for lung transplantation.
The patient underwent transplantation of her heart and both lungs. Figure 1 shows the gross
cut surface of one of her native lungs. The remaining figures show microscopic views of sections taken
from her native lungs. Figures 3, 4 and 5 are consecutively higher powers of one lesion.

A 60 year old woman was found to have a right middle lobe lung mass on chest x-ray while undergoing
follow-up for a non-invasive, papillary, transitional cell carcinoma of the bladder. She had mild
progressive dyspnea and a slight, productive cough. Pulmonary function showed mild obstruction and
decrease in the diffusing capacity. She had a 70 pack year history of smoking but had quit for one
year. At thoracotomy, multiple pulmonary nodules were found in the right middle lobe and removed
surgically. Three of the nodules measured 1.0, 0.7 and 0.6 cm in diameter. A right middle lobectomy was

The patient was a 41 year old gay male who was HIV positive and fulfilled the criteria for AIDS. He
had been placed on HAART (Highly Active Anti-Retroviral Therapy) for 5 weeks.
The patient presented with cough, fever, malaise, and weight loss. He did not have hemoptysis. The
CD4 count was greater than 100.
The CT scan showed bilateral infiltrates associated with bronchial thickening and bronchial
obstruction. A bronchoscopy was performed and found bronchial nodules of soft yellow tan tissue. A
biopsy of the nodules was performed.

A 30-year-old Black woman presented with a progressive shortness of breath and productive cough over
the last six months associated with chest radiographs showing a bilateral reticulonodular pattern with
bronchiectasis, greatest in the left lower lobe. Repeated cultures of sputum were negative. Past
medical history is pertinent only for a history of ulcerative colitis for which she had a colectomy in
1994. Pulmonary function studies showed predominantly obstructive lung disease. A diagnostic
thoracoscopic biopsy was performed (Case contributed by Michael D. Kanzer, MD, Christiana Care Health
Services, Newark, Delaware).

A 50-year-old white female, status post bilateral modified radical mastectomies and chemotherapy 3
years earlier for breast cancer, developed a left upper lobe mass that grew from 2.4 cm to 5.5 cm in
maximum dimension over 3 months. Other medical history included probable systemic lupus erythematosus
with ocular sicca symptoms, arthralgias, and intermittent mild rash, treated with hydroxychloroquine.
Bronchoscopy with bronchial biopsy was negative for malignancy. A PET scan showed increased activity in
the left lung and hilar and mediastinal lymph nodes. Left upper lobectomy and thoracic lymphadenectomy
were performed. Gross examination of the left upper lobe revealed an ill-defined 6.5 cm zone of tan
consolidation with foci of necrosis, and bronchiectasis with thick brown mucus plugs.
