| Body area | N | Mean (SD) MC/mm2 |
|---|---|---|
| Perilesional skin around basal cell carcinomas, various dermatological disorders, and the control group. | ||
| *Difference in MCs/mm2 between trunk, upper arm, and upper leg: p = 0.929; **difference of MCs/mm2 between proximal and distal body areas: p = 0.000; ***difference of MCs/mm2 between forearm and lower leg: p = 0.240 (all Student’s t test). | ||
| Proximal: trunk, upper arm, and upper leg; distal: forearm and lower leg. | ||
