Osseous involvement in pediatric Hodgkin's lymphoma

Area of Science:

• Pediatric Oncology
• Hematology
• Skeletal Radiology

Background:

• Pediatric Hodgkin's lymphoma (HL) is a significant malignancy in children and adolescents.
• Bone involvement in pediatric HL is uncommon but can impact diagnosis, staging, and treatment.
• Understanding the characteristics of osseous involvement is crucial for optimizing patient care.

Observation:

• Three pediatric patients (4.5%) out of 66 with Hodgkin's lymphoma presented with bone involvement over 3.5 years.
• Common symptoms included local bone pain and B-symptoms; vertebrae and pelvis were most frequently affected.
• Radiographic findings often showed an osteolytic pattern.

Findings:

• Nodular sclerosis was the predominant histological subtype in these cases.
• Two patients had bone lesions at relapse, while one had concurrent non-osseous disease.
• Combined modality treatment was administered to most children, leading to good overall response and survival.

Implications:

• Highlights the importance of considering skeletal surveys in the evaluation of pediatric Hodgkin's lymphoma, especially at relapse.
• Suggests that despite bone involvement, pediatric HL patients can achieve favorable outcomes with appropriate treatment.
• Informs clinical practice regarding the presentation and management of osseous Hodgkin's lymphoma in pediatric populations.
