(b) Mean number (N) ± SD and range of values in brackets of epidermal (e) and dermal (d) CD1a+ LCs/1 HPF, in DD, PV, LRP, and in the normal skin (NSk). P significance is reported at the bottom.

	DD	PV	LRP	NSk
	N ± SD (range)	N ± SD (range)	N ± SD (range)	N ± SD (range)
eCD1a+ LCs	2.4 ± 2 (0–7)	5.4 ± 1.7 (3–10)	20.9 ± 3 (15–28)	9.9 ± 2.1 (7–14)
dCD1a+ LCs	3.4 ± 1.1 (2–7)	4.9 ± 1.6 (2–7)	18.5 ± 5.5 (10–26)	5.7 ± 1.4 (4–8)

P not significant for: CD3 and CD20, among DD, PV, and LRP groups; and for CD4+, CD25+FOXP3+ Tregs, and CD8+ in PV versus LRP.

For all the other comparisons, P < .05.

LCs: Langerhans cells, Tregs: regulatory T cells, and pDCs: plasmacytoid dendritic cells.
