Abstract
BACKGROUND
Lymphomatoid granulomatosis is a EBV-driven lymphoproliferative disorder that has been reported in association with immunodeficiency, but only exceptionally in patients with hematopoietic malignancy.
CASE REPORT
A 14-year-old boy with trisomy-21 and a history of B-lymphoblastic leukemia/lymphoma (B-ALL) diagnosed 1.5 years prior, on maintenance chemotherapy, presented with fever and respiratory symptoms. Chest X-ray revealed right-lower-lobe consolidation. He was treated for pneumonia but continued to be febrile with worsening respiratory status, with development of additional pulmonary and liver nodules. No infectious etiology was identified. Following nondiagnostic lung and liver biopsies, the largest pulmonary mass was resected. The histopathologic findings were diagnostic of lymphomatoid granulomatosis. There was no residual B-ALL. The patient's status continued to deteriorate and he died shortly thereafter.
CONCLUSION
Relative immunosuppression due to maintenance therapy for B-ALL can lead to lymphomatoid granulomatosis.
