A, A 53-year-old man sustained an immature elevated keloid on his chest that was associated with pain and itching. The white line indicates the location examined by the linear probe used for the ultrasound elastography. B, The ultrasound elastography image. The white arrow shows the separation between the normal skin and the keloid. The hyperechoic area on the left is the normal skin, and the hypoechoic area on the right is the keloid. Each strain was measured in the range enclosed by a square in the normal dermis and in the range enclosed by a circle in the keloid. The extent of the strain of the tissue is related to its stiffness, and the value decreases as the tissue becomes harder. The strain ratio defined as the value of the normal dermis/keloid was 21.0.

A, A 31-year-old woman developed a mature flattened keloid on her left shoulder after treatment with intralesional steroid injections. The white line indicates the location examined with the linear probe. B, The ultrasound elastography image. The white arrow shows the separation between the normal skin and the keloid; the area on the left is the normal skin and the area on the right is the keloid. The keloid lesion had a similar echo signal to normal skin, but it appeared slightly atrophic. The strain ratio (normal dermis/keloid) was 0.76.
