(1) However, the patient had desquamative interstitial pneumonitis and superimposed bronchopneumonia, not pulmonary embolism.(2) The combination of sebum and desquamated cells provides an environment that is ripe for the growth of Propionibacterium acnes, the principal organism in inflammatory acne lesions.(3) Sections showed early patchy bronchopneumonia, centriacinar emphysema, and desquamative interstitial pneumonitis.(4) They include nausea, vomiting, an increased susceptibility to infection, oral mucositis, diarrhoea, desquamation of the palms and soles, and, rarely, cardiac and neurological toxic effects.(5) Scarlet fever provides the classic example of an erythematous rash with subsequent desquamation .(6) Transmission can occur by direct contact or from exposure to desquamated cells.(7) Dermoids are composed of mature epithelial tissues, a combination of skin, hair, desquamated epithelium, and teeth.(8) TrkA immunofluorescence was detected both in desquamated epithelial cells and inflammatory cells recovered from RSV-infected airways.(9) At the periphery of the tumor, the crystal-laden cells infiltrated the interstitium and also occupied the alveoli in a desquamative interstitial pneumonia-like pattern.(10) Participants were asked about the dermatologic effects of the protocols with regard to dryness, desquamation , and irritation.(11) Local tissue reactions were confined to the treatment site and included erythema, swelling, desquamation , erosions, and eschar in most patients.(12) Widespread erythema, particularly if associated with soreness, is usually caused by desquamative gingivitis.(13) Small numbers of epithelial giant cells were found admixed with acute inflammatory cells in the lamina propria and even among desquamated cells within the lumen of the appendix.(14) This interfered with the normal process of desquamation , resulting in a build-up of keratin (retention hyperkeratosis).(15) Red lesions may also be due to desquamative gingivitis, erythroplasia, haemangiomas, orofacial granulomatosis, Crohn's disease, sarcoidosis, Wegener's granulomatosis, and neoplasms such as carcinoma and Kaposi's sarcoma.
