Abstract
- Approximately half of the patients with systemic lupus erythematosus(SLE) develop localized or diffuse lymphadenopathy during the evolution of the disease. But hilar and mediastinal lymph node enlargement due to SLE is rare. The histologic findings of lupus lymphadenitis range from nonspecific lymphadenitis with variable degrees of cellular necrosis to the less common but more specific appearance of extensive necrosis. Advanced lesions are characterized by hematoxylin bodies and condensation of DNA on the vessel walls. Hematoxylin bodies are amorphous homogeneous violet or lilac colored structures composed of partially depolymerized DNA, mixed with protein, carbohydrates and globulins which may be seen deposited on vessel walls and within the paracortex of lymph node. They are virtually diagnostic of SLE and would exclude malignant lymphoma. SLE with mediastinal lymphadenopathy is rare so we report this case with a review of literatures, which was diagnosed by hematoxylin bodies on pathologin findings of cervical lymph node.
