Indolent diffuse histiocytic lymphoma with sclerosis and chylous effusions

Area of Science:

• Oncology
• Hematology
• Pathology

Background:

• Diffuse histiocytic lymphoma (DHL) is an aggressive non-Hodgkin lymphoma.
• Sclerosis is a rare pathological finding in DHL.
• Chylous effusions present a diagnostic and therapeutic challenge.

Observation:

• A patient presented with DHL and sclerosis, complicated by chylous pleural and peritoneal effusions.
• The disease course spanned four years from symptom onset to diagnosis.
• Diagnostic workup included imaging and histopathological examination.

Findings:

• Combination chemotherapy followed by consolidative radiotherapy led to clinical improvement.
• The patient achieved disease-free status 14 months post-treatment.
• Histopathological analysis confirmed diffuse histiocytic lymphoma with sclerotic features.

Implications:

• This case highlights the importance of recognizing rare DHL subtypes and managing complex effusions.
• Effective treatment regimens can lead to long-term remission in challenging cases.
• Further research into DHL with sclerosis and chylous effusions is warranted.
