Not Just Skin Deep: Systemic Disease Involvement in Patients With CutaneousLupus.

Abstract

Cutaneous lupus erythematosus, specifically discoid lupus erythematosus, disproportionately affects those with skin of color and may result in greater dyspigmentation and scarring in darker skin types. In this article, we review investigations relevant to cutaneous lupus patients with skin of color at University of Texas Southwestern Medical Center, associations and risk of progression to systemic lupus, and recommendations for monitoring for systemic disease spread. Between 5% and 25% of patients with cutaneous lupus can develop systemic lupus. If they progress to systemic disease, patients often develop mild systemic disease with primarily mucocutaneous and musculoskeletal manifestations. Patients with cutaneous lupus should be followed up closely to monitor for systemic disease involvement. The University of Texas Southwestern Cutaneous Lupus Erythematosus Registry, of which almost two thirds of participants are those with skin of color, is a part of an ongoing effort to better understand the pathophysiologic mechanisms of CLE and to identify prognostic indicators of risk of progression to systemic lupus.
