Pseudoatrophoderma colli is a rare, benign condition of the upper trunk and neck.
There is a slow and usually asymptomatic development of atrophic-appearing macules on the neck and upper trunk. The appearance of the initial lesions, which tend to be hypopigmented and depressed, may resemble vitiligo. They have a glossy or shiny appearance with wrinkling that can be reduced by stretching the skin. It occurs most commonly on the neck but on the upper trunk as well. In some instances, pseudoatrophic plaques continue to spread over the trunk and occasionally appear in other regions, such as the buttocks, the arms, and the lower part of the abdomen. The disease tends to spread gradually for years to decades. It is usually asymptomatic, but occasionally causes mild pruritus.
Spontaneous resolution may occur. One case responded well to topical 5% lactic acid ointment.
