Histological characteristics of DCH-positive feline lymphoma cases.
| Case no. | Lymphoma subtype/anatomical form | Histological Grading | WHO classification | DCH loads (copies/ml) | ISH scorea | ISH staining pattern | Feline retroviral statusb |
|---|---|---|---|---|---|---|---|
| 1 | B-cell/Multicentric | Low grade | Peripheral B cell | 2.35 × 104 | + | Focal, dot-like pattern | Negative |
| 2 | B-cell/Multicentric | High grade | Diffuse large B-cell | 2.82 × 104 | + | Focal, dot-like pattern | FeLV |
| 3 | B-cell/Multicentric | Low grade | B-cell small lymphocytic | 3.84 × 106 | +++ | Multifocal, multiple dot-like pattern | Negative |
| 4 | B-cell/Multicentric | Low grade | Follicle center | 1.80 × 107 | +++ | Diffuse, intensity | FeLV |
| 5 | B-cell/Multicentric | High grade | Diffuse large B-cell | 1.28 × 106 | ++ | Patchy, multiple dot-like pattern | Negative |
| 6 | B-cell/Multicentric | Low grade | Follicle center | 1.11 × 106 | ++ | Focally extensive, multiple dot-like pattern | FeLV |
aThere is no significant correlation between DCH loads and DCH staining pattern (p = 0.067).
