Answer : D Suppurative lymphadenitis
Acute suppurative lymphadenitis occurs in the lymph nodes that drain a site of acute bacterial infection.
Suppurative lymph nodes enlarge rapidly because of edema and hyperemia and are tender due to distention of the capsule.
Microscopically, infiltration of the lymph node sinuses and stroma by polymorphonuclear leukocytes and prominent follicular hyperplasia are noted.
Neutrophils are not a morphologic feature of the other choices
