Interfollicular Hodgkin's disease: an uncommon pattern that may cause diagnostic difficulty

Area of Science:

• Oncology
• Pathology
• Hematology

Background:

• Interfollicular Hodgkin's disease is a rare pattern of Hodgkin's lymphoma involving lymph node interfollicular areas.
• It can be mistaken for reactive lymph node hyperplasia, complicating diagnosis.

Purpose of the Study:

• To highlight the diagnostic difficulties associated with interfollicular Hodgkin's disease.
• To emphasize the importance of recognizing this pattern for timely Hodgkin's lymphoma treatment.

Main Methods:

• Retrospective analysis of eleven cases diagnosed over five years.
• Review of lymph node biopsies, including histopathology and immunohistochemistry (CD15, CD30).

Main Results:

• Eleven cases of interfollicular Hodgkin's disease were identified.
• Patients were predominantly under twenty years old with localized lymphadenopathy.
• Histopathology revealed follicular hyperplasia with interfollicular infiltration by inflammatory cells and characteristic Reed-Sternberg/Hodgkin's cells.

Conclusions:

• Interfollicular Hodgkin's disease requires careful pathological examination to differentiate from reactive hyperplasia.
• Immunohistochemistry is vital for identifying atypical cells (CD15+, CD30+) in this specific Hodgkin's lymphoma subtype.
