We describe the case of a 4-year-old boy, with a positive family history of multibacillary leprosy (borderline-borderline) in his 12-year-old sister. The patient was diagnosed to have borderline lepromatous (BL) leprosy, BI of 4 + and had two erythematous, infiltrated plaques over the scrotum. He developed type reaction, 3 months following initiation of multibacillary multidrug therapy (MB-MDT) and responded favourably to systemic corticosteroids.
