Both LIP and low grade lung lymphoma may "transform" to a high grade lymphoma UIP, usual interstitial pneumonitis; NSIP, nonspecific interstitial pneumonitis; DIP, desquamative
interstitial pneumonitis; RB-ILD, respiratory bronchiolitis-ILD; AIP, acute interstitial pneumonitis; BOOP, bronchiolitis obliterans organizing pneumonia; LIP, lymphocytic interstitial pneumonitis.
With descriptions in the medical literature dating to the 1950s, the signs and symptoms of desquamative
inflammatory vaginitis (DIV) include dyspareunia and exudative, chronic vaginitis, with yellow-watery, purulent discharge that is occasionally blood-tinged, said Dr.
10) Desquamative interstitial pneumonitis (DIP) has been described in two patients with HCV infection.
This new categorization recognizes six entities: usual interstitial pneumonia or IPF, nonspecific interstitial pneumonia, desquamative interstitial pneumonia (DIP), respiratory bronchiolitis-associated lung disease, cryptogenic organizing pneumonia, and lymphoid interstitial pneumonia.
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.

29,39,207,208) More pronounced cases of RBILD merge in the continuum with cases of desquamative
interstitial pneumonia (29) (Figure 12).
107) Variable numbers of alveolar macrophages are seen and, in some cases, may be sufficiently numerous as to suggest desquamative
Some cases showed focal areas with distal airspaces filled by alveolar macrophages in a pattern resembling desquamative
Pigmented macrophages typically accumulate in bronchioles and peribronchiolar airspaces, a lesion referred to as respiratory bronchiolitis, which may mimic desquamative
interstitial pneumonia both radiologically and histologically (so called, desquamative
interstitial pneumonia-like changes).
It should be noted that some cases of congenital PAP may have pathologic findings of desquamative
interstitial pneumonitis on transbronchial biopsy, with typical PAP histologic findings only in subpleural areas.
Smokers are at increased risk for a number of pulmonary diseases, including 3 forms of interstitial pneumonia: respiratory bronchiolitis-associated interstitial lung disease, desquamative
interstitial pneumonia, and PLCH.
