The differential diagnosis includes other causes of desquamative
gingivitis and cicatricial conjunctivitis, which include pemphigus vulgaris, erythema multiforme, dermatitis herpetiformis, aphthous stomatitis, and Behcet's disease.
The overlap between respiratory bronchiolitis and desquamative
interstitial pneumonia in pulmonary Langerhans cell histiocytosis: high-resolution CT, histologic, and functional correlations.
Some pathologists used diagnoses of organizing pneumonia, desquamative
interstitial pneumonia, respiratory bronchiolitis, or diffuse alveolar damage.
Among the histiocytic/macrocytic lesions are respiratory bronchiolitis and desquamative
interstitial pneumonia, Erdheim-Chester disease (ECD), and hypersensitivity pneumonitis.
As described and referenced in the preceding paragraphs, the histologic appearance of lung injury secondary to cigarette smoke is a constellation of findings that includes smokers' macrophages within airspaces, which may be airway centered (respiratory bronchiolitis) or diffuse (desquamative
interstitial pneumonia) in distribution; emphysema; small-airway injury evidenced by submucosal and adventitial fibrosis, remodeling that results in distortion, and increased bronchus-associated lymphoid tissue; thickening of walls of small arteries and arterioles; stellate cellular and/ or fibrotic lesions of pulmonary Langerhans' cell histiocytosis; and alveolar wall fibrosis (Figure, c through g).
In addition to traditional entities, such as emphysema, respiratory bronchiolitis, and desquamative
interstitial pneumonia, it is now recognized that cigarette smoke may result in alveolar wall fibrosis, a pathologic change that, in combination with emphysema, may have significant clinical and physiologic implications.
(4) The purpose of this short article is to suggest how RBF fits into the general category of smoking-related ILD, and particularly to compare it with two possibly related forms of accepted smoking-related ILDs: respiratory bronchiolitisinterstitial lung disease (RBILD) and desquamative
interstitial pneumonia (DIP).
If prominent areas of desquamative
interstitial pneumonia-like changes are seen with macrophages that lack anthracotic smoking pigment, one should consider the possibility of an underlying myelodysplastic syndrome or drug-induced pneumonitis.
Alveolar macrophages Obstructive diseases, drug reactions, respiratory bronchiolitis, smoking-related interstitial disease (respiratory bronchiolitis-associated interstitial lung disease, desquamative
interstitial pneumonia, pulmonary Langerhans cell histiocytosis) 3.
interstitial pneumonia is also associated with smoking in most cases.
The most common HRCT findings in patients with RA-ILD are usual interstitial pneumonia (UIP) (Figure 1), nonspecific interstitial pneumonia (NSIP) (Figure 2), lymphocytic interstitial pneumonia, organizing pneumonia, diffuse alveolar damage, respiratory bronchiolitis, and desquamative
interstitial pneumonia (11).
