We present a young adult female with symptoms of acute tonsillitis and tender cervical
lymphadenopathy. Despite a full course of oral antibiotics, she had persistent left lower cervical
lymphadenopathy measuring 2.0 x 1.5 cm at 2 weeks post-treatment. Rigid and flexible scope
examinations did not reveal any abnormalities in the nasopharynx, oropharynx or hypopharynx.
Tuberculosis tests were negative and blood index results were normal. Fine needle aspiration cytology
revealed a non-specific granulomatous inflammatory process. Excisional lymph node biopsy was
performed, and the patient was diagnosed as having Kikuchi’s Disease (KD). We would like to highlight
the diagnostic challenges in detecting this condition and the importance of differentiating KD from
tuberculosis and malignant lymphoma, the latter of which requires aggressive treatment.
