Three cases of papular tuberculid after bacille calmette-guerin vaccination

We reported three cases of papular tuberculid after receiving Bacille Calmette-Guerin (BCG) vaccination. Case 1 was a 5-month-old girl who developed eruptions on her extremities five weeks after the BCG vaccination. Case 2 was a 6-month-old boy who developed eruptions on his extremities one month after the BCG vaccination. Case 3 was a 5-month-old boy who developed eruptions all over his body 6 weeks after BCG vaccination. Histopathologically, dermal perivascular lymphocytic inflammatory infiltrate and non-caseous epithelioid cell granulomas were observed in all cases. We diagnosed these cases as papular tuberculid resulting from BCG vaccination. All lesions resolved in three months without treatment. To establish the diagnosis when discrete eruptions are observed in a child under one year old, it is important to ask the guardians about the time of BCG vaccination.
