表1 淋巴滤泡破坏程度分级Table 1 Grading of lymphoid follicular architecture disruption |
| Grade | Name | Histomorphological features |
| G0 | Architecture-intact type | A continuous, dense CD21 meshwork surrounds a well-defined BCL6-positive germinal center; The follicular contour is intact, with no disruption |
| G1 | Marginal thinning/eccentric type | The CD21 meshwork remains continuous but shows peripheral “crescent-shaped” condensation toward the outer margin or focal thinning; The germinal center remains intact |
| G2 | Disrupted with preserved outline type | The CD21 meshwork shows breaks and/or gaps; The follicular outline is still preserved. Features suggestive of tumor cell “follicular colonization” are present (BCL6-positive areas are intercalated by non-germinal-center cells) |
| G3 | Outline-loss type | The follicular contour is indistinct or largely lost; Only scattered fragmentary CD21 meshwork persists, and BCL6-positive germinal-center cells are no longer detectable |
| G4 | Absent/disintegrated type | The CD21 meshwork is almost completely unrecognizable/absent; Germinal centers are lost, or only rare scattered BCL6-positive cells are seen |
CD21, complement receptor type 2; BCL6, B-cell lymphoma 6 protein. |
