Question of the Week
For May 24, 2016
A 10-year-old girl presents for follow-up of cervical lymphadenopathy. She was initially evaluated 14 days ago for a left cervical lymph node that had been progressively enlarging for 10 days. She was treated empirically for lymphadenitis with a 14-day course of clindamycin.
Despite this treatment, the cervical lymphadenopathy has progressed. A 3-cm x 4-cm mass is palpable in the anterior cervical lymph-node chain. There is mild tenderness to palpation but no overlying erythema or fluctuance. There are no other enlarged lymph nodes or signs of systemic disease.
A purified protein derivative test was placed and found to be negative.
Which one of the following next steps is most appropriate in this patient’s care?
