Figure 4

A: This figure is an example of the ultrasound image of a false positive case. The area surrounding letter E represents the area judged to be positive by the ultrasound for subclinical extension, however, no evidence of tumor in this area was observed on histology (false positive). This case was cleared in 1 stage of Mohs surgery.

B: This is the correlated histopathology of the area photographed in Figure 4A. There is significant solar elastosis in the dermis, which may have confounded the ultrasound image.
