Pediatric lymphoma

Overview

Board takeaway: Investigate persistent unexplained lymphadenopathy or oral masses and coordinate dental care with lymphoma subtype, treatment, and current counts.

How do Hodgkin and non-Hodgkin lymphoma differ in children?

Classical Hodgkin lymphoma is characterized by Reed–Sternberg cells in the appropriate tissue context. Non-Hodgkin lymphoma comprises distinct lymphoid malignancies, including mature B-cell, lymphoblastic, and anaplastic large-cell disease. Pediatric forms and protocols differ from adult lymphoma.

Which findings should raise concern for pediatric lymphoma?

Persistent or progressive lymphadenopathy, unexplained fever, drenching night sweats, weight loss, organ enlargement, or an abdominal mass requires assessment. Oral or jaw swelling, tonsillar enlargement, dysphagia, paresthesia, or rapidly developing bone loss can occur. A chest mass can compromise airway or circulation and is important before sedation or general anesthesia.

What oral complications can follow lymphoma treatment?

Mucositis, bleeding, infection, taste change, and dry mouth may occur. Treatment during tooth development can affect crown size, enamel, tooth number, roots, and eruption. Head and neck radiation or transplantation adds exposure-specific risks; document actual treatment rather than assigning every late effect to every survivor.

How should dental care be coordinated during lymphoma treatment?

1. Before therapy: assess dental disease and prioritize infection, nonrestorable teeth, periodontal disease, and traumatic sources when feasible.
2. During therapy: review the expected nadir, current blood counts, medication, and planned procedure with oncology.
3. Urgent care: obtain a coordinated antibiotic and hemostatic plan when needed; one ANC or platelet cutoff is not automatic clearance.
4. Prevention: maintain tolerable oral hygiene, fluoride, and symptom support without traumatizing painful tissues.
5. After therapy: follow tooth development, saliva, function, and relevant long-term organ effects.

What determines treatment and prognosis in pediatric lymphoma?

Subtype, stage, biologic features, and response determine chemotherapy, immune or targeted therapies, and selected radiation or surgical roles. Many pediatric lymphomas are highly treatable. Prognosis figures from adults under age fifty should not be presented as pediatric survival estimates.
