Biopsy specimens of lung parenchyma are obtained from patients recovering from influenza pneumonia and healthy control subjects. Compared to the lung tissue from the healthy control subjects, the lung tissue from the affected patients is most likely to show which of the following findings on histopathologic examination?? A: Decreased alveolar macrophages, B: Decreased interstitial fibroblasts, C: Increased type II pneumocytes, D: Increased alveolar squamous epithelial cells, E: Increased goblet cells,  <response>: This is a histopathology question asking about the expected findings in lung tissue of patients recovering from influenza pneumonia compared to healthy controls. Influenza pneumonia causes damage to the alveolar epithelium, which leads to compensatory proliferation of type II pneumocytes to replace the damaged type I pneumocytes. Macrophages may be increased to clear debris but are not the main histological change. Fibroblasts may be increased later in repair but not in acute infection. Squamous metaplasia and goblet cell metaplasia do not occur. Therefore, the increase in type II pneumocytes is the best answer.C: Increased type II pneumocytes
