We report a rare case of herpes simplex virus (HSV) bronchopneumonia in an
otherwise healthy middle-aged individual. Bronchoscopy indicated scattered
white-coated lesions in the bronchial mucosa. The diagnosis was established
following immunohistopathological staining for HSV of specimens obtained b
y bronchial biopsy. This case suggests that HSV could be a pathological age
nt of not only oral and genital mucosal lesions but also lower respiratory
tract infection.
