Abstract
The Bacillus Calmette-Guérin (BCG) vaccine, a cornerstone in global immunization programs for tuberculosis prevention, has generally proven to be safe and effective. However, rare complications, including localized abscess formation, have been reported. This case report highlights a two-year-old male who developed a painless swelling on the left chest wall, noticed six weeks post-BCG vaccination. Physical and imaging evaluations confirmed a cold abscess. Laboratory tests ruled out alternative diagnoses. Antitubercular therapy led to a favorable response, avoiding surgical intervention. Follow-up revealed complete resolution, showcasing successful management of this rare BCG-related complication in a pediatric patient. The success of antimycobacterial therapy supports a tailored and conservative approach, raising questions about the necessity of surgical intervention. The presented case…
