Osteitis of the humerus following BCG vaccination
Tubercle
|December 1, 1984
Insights
A rare BCG vaccine complication occurred in a Saudi child, presenting as a granulomatous lesion on the humerus. This case highlights potential side effects of the Bacillus Calmette-Guerin vaccine.
Area of Science:
- Pediatric Infectious Diseases
- Immunology
- Dermatopathology
Background:
- Bacillus Calmette-Guerin (BCG) vaccination is a widely used tuberculosis preventative measure.
- While generally safe, BCG can rarely cause localized or systemic adverse events.
- Understanding BCG vaccine complications is crucial for pediatricians and public health officials.
Observation:
- A 22-month-old Saudi child presented with a granulomatous lesion on the left humerus.
- The lesion appeared 15 days after the child received BCG vaccination in the deltoid region.
- Clinical presentation, diagnostic investigations, and histopathological findings were documented.
Findings:
- Histopathology confirmed a granulomatous inflammatory process at the vaccination site.
- The case is consistent with a known, albeit infrequent, complication of BCG vaccination.
- Review of literature indicates varying frequencies of BCG-induced granulomas.
Implications:
- This case underscores the importance of recognizing and managing rare BCG vaccine side effects.
- Accurate diagnosis and reporting contribute to pharmacovigilance and vaccine safety monitoring.
- Further research may elucidate risk factors and optimal management strategies for BCG-related granulomas.
Abstract:
A 22-month-old Saudi child developed a granulomatous lesion of the left humerus following BCG vaccination in the overlying deltoid area 15 days after birth. The clinical picture, investigations and the histopathology reports are presented. The literature regarding BCG vaccine complications and their frequency is reviewed.
