Figure 1.
(A) The numbers of mast cells (MCs) were determined in three different biopsy groups, using anti-tryptase antibody staining and expressed as MC/mm2. No differences were found between perilesional skin biopsies around basal cell carcinomas (BCCs), perilesional skin around various dermatological disorders, and control skin (p = 0.560). (B) From these three biopsy groups, the numbers of MCs were determined in five different body sites; p values for differences in MC numbers in the trunk, upper arm, and upper leg were not significant (0.929), and neither were p values for differences between the forearm and lower leg (p = 0.240). (C) Body sites with similar MC numbers were placed into two groups. The “proximal” group was formed by the trunk, upper arm, and upper leg, whereas the “distal” group was formed by the forearm and lower leg (unpaired Student’s t test, p < 0.001).
