    Area of Science:

    • Oncology
    • Hematology
    • Pediatric Medicine

    Background:

    • Multiple myeloma is a rare malignancy in children.
    • Extramedullary disease, such as nasopharyngeal plasmacytoma, is uncommon in pediatric multiple myeloma.

    Observation:

    • A 12-year-old girl presented with a nasopharyngeal mass.
    • Histological and immunohistochemical analyses confirmed plasmacytoma with IgA-kappa monoclonal protein.
    • Bone marrow biopsy showed approximately 20% atypical plasma cells.

    Findings:

    • The patient was diagnosed with multiple myeloma.
    • She became refractory to chemotherapy after 1 year of treatment.
    • Five months post-therapy cessation, a significant objective response was observed with stable IgA levels.

    Implications:

    • This case highlights the importance of considering multiple myeloma in pediatric patients with extramedullary masses.
    • The unusual presentation and treatment response underscore the need for further research into pediatric multiple myeloma.
    • Long-term monitoring is crucial for patients with pediatric multiple myeloma, even after apparent treatment failure.
