Syncytial Variant Nodular Sclerosis Classical Hodgkin Lymphoma in an Adolescent and Review of the Literature: A Unique Entity

摘要

Syncytial variant of nodular sclerosis (SV-NS) classical Hodgkin lymphoma (cHL) with its histologic features and clinical presentation is uncommon in adults and extremely rare in children. Here, we report a female teenager presenting with long-standing B symptoms, prominent soft tissue and bone involvement mimicking sarcoma and significant nodal disease who is diagnosed with advanced SV-NS cHL. Rare Reed-Sternberg-like cells displaying neutrophil and erythrocyte emperipolesis were seen on bone marrow aspiration slides. Despite initial complete response to chemotherapy and radiotherapy, the patient experienced early relapse suggestive of high-risk biology. This variant may constitute a unique entity.
