| Microscopic | Follicular hyperplasia, scattered immunoblasts, and plasma cells with increased vascularity with Azzopardi phenomenon | Irregular paracortical areas of coagulative necrosis with abundant karyorrhectic debris, and abundance of histiocytes at the margin of the necrotic area |
| Immunohistochemistry | CD4+ with predominance of CD8+ T lymphocytes | CD8+ T lymphocytes myeloperoxidase+ CD68 and CD 123+ |
| SLE – systemic lupus erythematosus; KFD – Kikuchi-Fujimoto disease; ANA – anti-nuclear antibodies; Anti-dsDNA – anti-double-stranded deoxyribonucleic acid antibodies. | ||
