Clinical presentation revealed solitary red, brown, pink, or yellowish macules, papules, nodules, or plaques. B\u2010mode ultrasound showed mild hypoechoic dermal thickening, which was more evident in the superficial dermis in 91.7% of cases and diffuse in one patient (8.3%). Color Doppler imaging showed no or mild vascularity. The lesion was rubbed with mild pressure using a tongue depressor. After the maneuver, an increase in the hypoechoic dermal thickening and the dermal vascularity was detected on color Doppler.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
