Ear and nose plaques

Based on the clinical appearance of hyperpigmented and hypopigmented scaly plaques in sun-exposed facial areas (with associated scarring and follicular plugging in affected lesions), the patient was given a diagnosis of discoid lupus erythematosus. The diagnosis was confirmed with a punch biopsy that showed characteristic interface dermatitis with superficial and deep perivascular and peri-adnexal lymphocytes. Direct immunofluorescence showed a band of C3 at the dermo-epidermal junction, consistent with various forms of cutaneous lupus.

A review of systems was negative for signs of systemic disease, including a lack of weakness, joint pain/swelling, fever, or known blood clots. An antinuclear antibody panel was also negative, largely excluding systemic disease.

Discoid lupus erythematosus is a form of cutaneous lupus. Patients often are genetically predisposed to autoimmune disease, and disease may be triggered by sun exposure. Up to 80% of patients develop lesions that are limited to the head and neck. Up to 25% of patients develop systemic lupus erythematosus that may occur months—or even decades—after the initial diagnosis. Lesions may lead to longstanding scars; this cannot always be prevented.

Two- to 3-week trials of topical potent or superpotent steroids applied to affected plaques may lead to clearance. Additionally, lesions may be treated with intralesional triamcinolone 3 mg/mL to 10 mg/mL and repeated every 3 to 4 weeks. Systemic therapies include hydroxychloroquine, chloroquine, retinoids, steroid sparing immunomodulators, and rarely prednisone.

This patient tolerated topical therapy well and though some scars remained, he was able to control flares with 2- to 3-week courses of clobetasol 0.05% twice daily. He is followed 2 to 3 times annually and has not developed signs or serologic findings of systemic disease over several years.
