Immunorecognition of 14F7 Mab in normal and non-malignant lesions of human skin.

Samples	No. cases (%)	Range intensity	Positive cells
(i) Normal skin	0/9 (0)	−	0
(ii) Nevi
Benign melanocytic nevi	2/11 (18,2)	+/++	3
Dermal	0/4 (0)	−	0
Junctional	0/1 (0)	−	0
Compound	2/6 (33,3)	+/++	3
Displastic melanocytic nevi	1/7 (14,3)	+	1

Intensity: − negative, + weak, ++ moderate, +++ intense. Positive cells: 0 (negative to less than 5%), 1 (6–25%), 2 (26–50%) and 3 (more than 50%).
