Jessner Lymphocytic Infiltrate

Key Points
Uncommon skin disorder
Cause unknown
May exhibit remissions in some cases
Consists of reddish nodules or plaques on the neck, upper back, and face

Jessner lymphocytic infiltrate is an uncommon skin disorder which often affects the neck, upper back, or face. The condition begins with red, elevated lesions which enlarge as the condition progresses to form well-defined plaques. In some cases the lesion center may remain clear. While the lesions are typically asymptomatic, some affected persons may experience itching or burning in the affected area. Additionally, affected persons may exhibit periodic remissions and exacerbations during the course of the condition.

It is unknown what causes Jessner lymphocytic infiltrate. With variable seasonal activity (i.e., affected persons see a deterioration during the winter months), it is though that the condition may be related to sun exposure.
