The number of CD11b⁺, CD14⁺, or complement factor I (CFI)⁺ cells and the staining score of iC3b in skin biopsies from patients with immunocomplex-mediated cutaneous small vessel vasculitis.

	CD11b (cells/mm2)	CD14 (cells/mm2)	CFI (cells/mm2)	iC3b (score)
Nonlesional skin (n = 10)	264 ± 162	224 ± 117	124 ± 144	1.3 ± 0.5
Initial petechiae (n = 10)	853 ± 605∗	576 ± 330#	270 ± 168&	1.6 ± 0.7
Palpable purpura (n = 8)	2040 ± 1202∗∗	1115 ± 606##	219 ± 69 (n = 9)	2.6 ± 0.7∗∗∗

The results are expressed as the mean ± standard deviation. “∗” denotes p = 0.014 and “∗∗” p = 0.004 when the CD11b⁺ cell numbers in the initial petechial lesion and palpable purpura, respectively, were compared to the corresponding cell numbers in the nonlesional skin (paired t-test); “#” denotes p = 0.008 and “##” p = 0.0024 when the CD14⁺ cell numbers in the initial petechial lesion and palpable purpura, respectively, were compared to the corresponding cell numbers in the nonlesional skin (paired t-test); “&” denotes p = 0.0169 when the CFI⁺ cell numbers in the initial petechial lesion were compared to the corresponding cell numbers in the nonlesional skin (paired t-test); and “∗∗∗” denotes p = 0.003 when the iC3b scores in the palpable purpura were compared to the corresponding scores in the nonlesional skin (mixed model analysis).
