A rare lung tumor in a boy with immune issues may need IVIG and bronchoscopic procedures

This case report describes a 10-year-old boy with congenital immunodeficiency who developed a rare lung tumor linked to the Epstein–Barr virus. The child received bronchoscopic interventions such as electrosnaring, forceps excision, laser therapy, high-frequency electrocautery, and cryotherapy, along with intravenous immunoglobulin therapy. Tumor cells showed diffuse positivity for Epstein–Barr virus and low Ki-67 levels between 5 and 8 percent. CD4+ T-cell counts remained persistently low throughout the case. No adverse events or discontinuations were reported in this single instance. The main concern is that tumor recurrence and progression may still occur despite these treatments. Because this is a single case report, the findings are limited and cannot be generalized to other patients. Clinicians should consider this rare tumor in pediatric patients with unexplained pulmonary nodules and underlying immunodeficiency. More research is needed to confirm the role of these therapies and to understand long-term outcomes for similar patients.
