All of the following features are seen in the viral pneumonia except (AIIMS Nov 2013)



A Presence of interstitial inflammation

B Predominance of alveolar exudate

C Bronchiolitis

D Multinucleate giant cells in the bronchiolar wall

Ans. A Bacterial lymphadenitis

a. Lymph nodes may be enlarged (lymphadenopathy) secondary to reactive processes, which can be either acute or chronic. Acute reaction (acute non specific lymphadenitis) can result in focal or generalized lymphadenopathy

b. Focal lymph node enlargement is usually the result of bacterial infection (bacterial lymphadenitis).

c. Sections from involved lymph nodes reveal infiltration by neutrophils. In contrast, generalized acute lymphadenopathy is usually the result of viral infections and usually produces a proliferation of reactive T lymphocytes called immunoblasts.

d. These reactive T cells tend to have prominent nucleoli and can be easily mistaken for malignant lymphocytes or malignant Hodgkin cells.
