Osseous involvement in pediatric Hodgkin's lymphoma.

Presented here is a report of 3 children, out of 66 total pediatric Hodgkin's lymphoma (HL) patients (4.5%) with bone involvement over a 3 and a half year period. Two patients presented with osseous lesions at the time of relapse and one had concurrent evidence of non-osseous disease. The clinical presentation, radiographic findings, histology, treatment and outcome of these patients are discussed. Boys and girls are nearly equally affected, local bone pain is the commonest symptom and B-symptoms are common. Vertebrae and pelvis are most frequently involved, commonly with an osteolytic picture. Nodular sclerosis is the predominant histological subtype. Most children received combined modality treatment and the overall response and survival are good.
