Jessner lymphocytic infiltrate is a chronic benign disease of the skin associated with T-cell infiltration. The disorder was first described more than 60 years ago by Jessner and Kanof.1 The etiology is uncertain; some postulate that it is a variant of lupus erythematosus or a CD8 polyclonal reactive pseudolymphoma.2
Patients present with asymptomatic erythematous papules or plaques of the face or trunk. The diagnosis is confirmed by biopsy, which demonstrates perivascular or periadnexal lymphocytic infiltration with normal epidermis. Differential diagnosis includes polymorphous light eruption, pseudolymphomas, and cutaneous lupus erythematosus.
Topical, intra-lesional, and systemic corticosteroids may promote resolution. Other options are antimalarials, tetracycline, dapsone, cryotherapy, and methotrexate.3,4
