A 25-year-old woman comes to the physician 2 days after noticing a mass in her right axilla. She also has a 1-week history of malaise, headaches, and night sweats. The patient says that she recently adopted a kitten and has sustained several bite and scratch marks. Her temperature is 37.8°C (100°F). Physical examination shows edema and tenderness of the right axillary lymph node. The skin over the node is erythematous, tough, and warm. There are scratches and bite marks of various ages over the upper extremities and hands. The result of an indirect fluorescent antibody test for Bartone/la henselae is positive. A biopsy specimen of this lymph node is most likely to show which of the following histologic patterns?
A) Diffuse neutrophil infiltration
