TABLE 2.
Scoring of collagen fibers (routine H&E stain) and elastic fibers (Orcein stain)7
| SCORE | COLLAGEN FIBERS | ELASTIC FIBERS |
|---|---|---|
| 0 | Normal | Normal |
| 1 | Collagen is fine and fibrillar | Short fragmented elastic fibers |
| 2 | Combination of 1 and 3 | Intermediate between 1 and 3 |
| 3 | Collagen is fibrotic, vessels are perpendicular to the epidermis | Fibrillar eleastic fibers, parallel to the epidermis |
| 4 | Combination of 3 and 5 | Intermediate between 3 and 5 |
| 5 | Collagen is extremely sclerotic and compacted in thick bundles | Absent or nearly absent |
