Osteitis secondary to BCG vaccine in immunocompetent patients: Three case reports.

Rationale: Osteitis corresponds to a rare but potentially serious complication reported in pediatric population after the application of the Bacillus Calmette-Guerin (BCG) vaccine. In the present study, 3 clinical cases associated with this entity are reported.

Patient Concerns: The 1st case corresponds to a 1-year-old female patient who presented an increase in the volume of the right pelvic limb after BCG application.
