title: Bronchiolitis obliterans associated with Stevens-Johnson Syndrome: histopathological bronchial reconstruction of the whole lung and immunohistochemical study.
abstract: This study presents an extremely rare case of constrictive bronchiolitis obliterans (BO) associated with Stevens-Johnson Syndrome (SJS) provides the morphological and immunohistochemical features using histopathological bronchial reconstruction technique. A 27-year-old female developed progressive dyspnea after SJS induced by taking amoxicillin at the age of 10. Finally, she died of exacerbation of type II respiratory failure after 17 years from clinically diagnosed as having BO. Macroscopic bronchial reconstruction of the whole lungs at autopsy showed the beginning of bronchial obliterations was in the 4th to 5th branches, numbering from each segmental bronchus. Once they were obliterated, the distal and proximal bronchi were dilated. Microscopic bronchial reconstruction demonstrated the localization of obliteration was mainly from small bronchi to membranous bronchioli with intermittent airway luminal narrowing or obliteration. Moreover, CD3-, CD20-, and CD68-positive cells were found in the BO lesions. CD34- and D2-40-positive cells were mainly distributed in the peribronchiolar lesions and bronchiolar lumens, respectively. SMA- and TGF-β-positive cells were seen in the fibrous tissue of BO lesions.
