We report a 1-year and 10-month-old male infant with complaining of knee pain and limping for 5 months. He received surgical debridement due to suspicion of malignancy but BCG osteomyelitis of the distal femur was diagnosed with the culture of the specimens which revealed to have Mycobacterium bovis-BCG strain. He was successfully treated with antituberculous therapy lasting for 1 year. © 2019 The Author(s) [2019]. Published by Oxford University Press.
