A Supraglottic Mass in a Pediatric Patient: An Unusual Presentation of Lymphoma

Abstract

Objective: To present a case of laryngeal lymphoma in a pediatric patient and perform a literature review of this rare entity. Patient: A 13-year-old male presented with a rapidly enlarging right neck mass. Work-up of the neck mass included a computed tomography scan of the neck with contrast and revealed a 2.5 cm right level II neck mass and an asymmetric lobulated soft tissue mass in the right pyriform sinus. Intervention: The patient underwent excisional biopsy of the right supraglottic mass. Once his diagnosis was confirmed, he was treated with a standard lymphoma protocol. Results: Intraoperative frozen analysis revealed a small blue cell tumor. Final pathology demonstrated diffuse large B-cell lymphoma of the germinal center B-cell subtype (GC-DLBCL). The patient underwent treatment with primary chemotherapy 12 days after his original procedure with cyclophosphamide, doxorubicin, vincristine, and prednisone. Conclusion: Laryngeal lymphoma remains extremely rare in the pediatric population. With appropriate treatment, the 5-year disease-free survival remains excellent for germinal center diffuse large B-cell lymphoma.
