Lupus Erythematosus Tumidus Clinical Characteristics and Treatment: A Retrospective Review of 25 Patients.

Lupus erythematosus tumidus (LET) is a rare photosensitive der-matosis that was considered a subtype of chronic cutaneous lupus erythematosus (CLE); however, its clinical course and favorable prognosis led to its reclassification into another category called intermittent CLE. Although known for more than 100 years, LET's association with systemic lupus erythematosus (SLE), autoantibody profile, and disease prognosis is not well characterized. The purpose of this study was to describe the demographics, clinical characteristics, autoantibody profile, comorbidities, and treatment of LET.
