A 7-year-old boy was referred to us for evaluation of an enlarging neck mass. The results of his primary care physician's initial clinical examination suggested lymph-adenopathy secondary to lymphadenitis, and the patient was treated over a 4-week period with two rounds of antibiotics. However, the mass did not resolve, and it subsequently became fluctuant. The patient was referred to our institution, where we diagnosed cat-scratch disease.
