BCGitis as the primary manifestation of chronic granulomatous disease

Abstract

Patients with primary immunodeficiency disease (PID) are not only vulnerable to mycobacterial disease, but are also more likely to develop adverse events following BCG vaccination. These events can range from regional disease (BCGitis) to disseminated disease (BCGosis). Chronic granulomatous disease (CGD), which is characterized by impaired leukocyte phagocytic function, is one of the many inherited PIDs that increase the body’s susceptibility to recurrent bacterial and fungal infections. Here, we report a 6-year-old boy with no significant past medical history who presented with progressive lymphadenopathy six years after BCG vaccination. He was later diagnosed with CGD on further evaluation.
