Figure 1. (A) Skin findings upon admission. Dark red erythema was
observed from both lower eyelids to the neck, and erosion with bloody
scabs was observed on the lips. Blisters and erythema with crusting were
scattered from the neck to the upper navel. (B) Chest X-ray showed
subcutaneous emphysema, bilateral mediastinal emphysema, and decreased
permeability in the bilateral middle and lower lung fields. (C) Chest CT
showed ground glass-like shadows in both lung fields, and the area only
below the pleura was spared. (D) Pathological findings of lung tissue
(hematoxylin-eosin staining, ×400). Collagen fibers proliferate in
highly thickened vesicles, fibroblast proliferation in the airspace,
extensive granulomatous scarring with interstitial fibrosis, and
post-bleeding changes were observed.
