Immunohistochemical Staining of Benign Nevi and Malignant Melanoma Specimens with Anti-Skeletrophin Antibody
| Lesion | Skeletrophin staining intensity | ||||
|---|---|---|---|---|---|
| n | − | + | ++ | +++ | |
| Benign nevi | 25 | 2 | 0 | 8 | 15 |
| Primary melanoma | |||||
| (superficial spreading melanoma) | 8 | 5 | 0 | 3 | 0 |
| (other than superficial spreading melanoma) | 30 | 13 | 8 | 5 | 4 |
The relative intensity of staining of tissues with anti-skeletrophin antibody was semiquantitatively scored as negative (−; <5%), weakly positive (+; 5> to 20%), moderately positive (++; >20 to 80%), or markedly positive (+++; >80%). n, number of specimens tested. Data are shown as the number of specimens negative or positive for skeletrophin staining. Benign nevi include both congenital and acquired types.
