Epidemiology
Estimated to account for ~45% of all NHL cases 1. Higher rates in North America and Europe 4.
Pathology
Nodal effacement by closely packed follicles containing small cleaved cells without nucleoli (centrocytes) and larger non-cleaved cells with moderate cytoplasm, open chromatin and multiple nucleoli (centroblasts).
Follicolar lymphoma is categorized into grades according the number of centroblasts per high-power fields(hpf) as follows5:
- grade 1: 0-5 centroblasts per hpf
- grade 2: 6-15 centroblasts per hpf
- grade 3: >15 centroblasts per hpf
Markers
- CD10: positive
- CD5: negative
- CD20: positive
Genetics
Translocation t(14;18) is found in the majority of patients with follicolar lymphoma.
Complications
Transformation to a more aggressive type of NHL.
Treatment and prognosis
