…Syphilis and fungal infections also show a form of granulomatous inflammation. In morphological classification, inflammation that primarily affects the parenchymal cells of each organ is called parenchymatous inflammation, and inflammation that occurs in the supporting tissue between the parenchymal tissue, i.e., the interstitium, is called interstitial inflammation. For example, in pneumonia, inflammation that directly damages the alveolar space where oxygen is exchanged is called pulmonary parenchymal inflammation, i.e., pneumonia, and when the main focus of the lesion is between the alveoli, which are the supporting tissue for the respiratory epithelium, it is distinguished as interstitial pneumonia. …
