Answer

Lesions become more diffuse with an underlying background of erythema. The face is commonly involved and is dry and scaly. Xerosis is prominent. Lichenification may be present. A brown macular ring around the neck is typical but not always present. It represents localized deposition of amyloid. See the image below.
