Case 1
A 62-year-old woman presented to the emergency room with shortness of breath of 6 months’ duration, which had worsened over the last 2 to 3 days before admission. Fever and weight loss exceeding 20 lb were also reported. The patient denied cough, orthopnea, and paroxysmal nocturnal dyspnea. Her past medical history included diabetes mellitus, hypertension, and congestive heart failure for which she was taking insulin, fosinopril, furosemide, and potassium supplements. She had an 80 pack-year
The Clinical Picture
Signs and symptoms reported by our patients were nonspecific, constitutional, and mild (Table 2). Dyspnea was the most common complaint and was exertional in one instance. Cough productive of scanty whitish sputum was reported by four patients. All diagnostic studies done on bronchial secretions were uninformative. Pleuritic chest pain was observed in one patient. There was no associated pleural effusion or pneumothorax. Different patterns of radiologic pictures emerged and included diffuse,
Discussion
Bronchiolitis obliterans with organizing pneumonia secondary to viral infections, toxic exposures, the use of certain medications, cocaine abuse, and HIV infection has been clearly described in the literature.9, 10, 11 The idiopathic variety of this entity, however, was only first described in 1985 by Epler et al.1 Careful history and relevant investigations are required to differentiate the idiopathic variety of BOOP from the secondary causes of BOOP, which were just mentioned.

2017, Human PathologyCitation Excerpt :CCOP was associated with a nodular pattern of radiographic infiltration and with persistence of these infiltrates despite therapy, in contrast to classical COP. Between 10% and 20% of patients with COP have progressive disease, with some rare cases having a fulminant course that terminates in the adult respiratory distress syndrome/diffuse alveolar damage [13,20,22-24]. A poor outcome in COP has been tied clinically to patients with underlying immunologic disorders especially autoimmune disease, severe hypoxemia, prior tobacco use, and bronchoalveolar lavage demonstrating increased eosinophils and neutrophils [21,25-28].
