Overview
Classification
According to the WHO criteria, the disease is morphologically graded into:[1]
- Grade 1 (<5 centroblasts per high-power field (hpf))
- Grade 2 (6–15 centroblasts/hpf)
- Grade 3 (>15 centroblasts/hpf).
- Grade 3A (centrocytes still present)
- Grade 3B (the follicles consist almost entirely of centroblasts)
The WHO 2008 update classifies
- Grades 1 and 2 now as low grade follicular lymphoma
- Grade 3A as high grade follicular lymphoma
- Grade 3B as Diffuse Large B Cell Lymphoma.
