Supraclavicular BCG Lymphadenitis Noted at 21 Months after BCG Vaccination Confirmed by a Molecular Method

Abstract

Bacille Calmette-Guérin (BCG) lymphadenitis is the most common complication of BCG vaccination. It commonly occurs in infants aged <6 months involving ipsilateral axillary lymph nodes. We described BCG lymphadenitis in a 22-month-old boy presenting swelling of left supraclavicular lymph node that was confirmed by real-time polymerase chain reaction (PCR) and the multiplex PCR targeting the region of difference (RD).
