Abstract
A 9-month-old boy was given a BCG vaccination at 7 months after birth. About 1 month following the vaccination, he exhibited pyrexia. Two weeks later, his mother noticed small papules on his trunk. These skin-colored or slightly red, pinhead-sized papules later spread to his limbs and face. Laboratory findings were negative for HCV Ab. HBS Ag, and EBV Ab. A biopsy specimen taken from the nodule showed a small granulomatous lesion in the dermis, that was negative for Ziehl-Neelsen stain. His tuberculin test was positive. The chest X-ray findings were otherwise normal. We thus diagnosed the boy to have lichen scrofulosorum following BCG. Without any specific therapy, these eruptions disappeared, and his fever completely disappeared. Over the next 7 months, he showed no recurrence.
