Summary
This study reports histiocytic necrotizing lymphadenitis without granulocytic infiltration outside Japan, frequently affecting young women. Further research is needed to clarify the etiology of this rare lymph node condition.
Area of Science:
- Pathology
- Histopathology
- Lymphadenitis
Background:
- An unusual form of necrotizing lymphadenitis, previously documented only in Japan, has now been identified in other global regions.
- This condition predominantly affects the cervical lymph nodes of young women.
Purpose of the Study:
- To report and characterize cases of histiocytic necrotizing lymphadenitis without granulocytic infiltration occurring outside Japan.
- To propose a diagnostic term based on histological findings.
- To discuss differential diagnoses and potential etiologies.
Main Methods:
- Histopathological examination of lymph node biopsies from affected individuals.
- Clinical data review for demographic and presentation patterns.
Main Results:
- Twenty-seven cases were identified in West Germany (23), Iran (1), Italy (1), Korea (1), and Spain (1).
- Histological features include infiltration by proliferating histiocytes, absence of granulocytes, and varying degrees of lymphoid tissue necrosis.
- The proposed term "histiocytic necrotizing lymphadenitis without granulocytic infiltration" reflects the key pathological findings.
Conclusions:
- The geographical distribution of this lymphadenitis has expanded beyond Japan.
- Histiocytic necrotizing lymphadenitis without granulocytic infiltration is a distinct clinicopathological entity.
- While the etiology remains unclear, a viral infection is a potential cause, warranting further investigation.
