Rare cause of periorbital and eyelids lesions: Discoid lupus erythematosus misdiagnosed as allergy

Ocular Discoid Lupus Erythematosus: More Than what Meets The Eye

Lupus erythematosus is a spectrum that includes auto-immune disorders such as systemic lupus erythematosus (SLE), subacute cutaneous lupus erythematosus (SCLE), and chronic cutaneous lupus erythematosus (CCLE). Discoid lupus erythematosus (DLE) is the most common type of CCLE, and ocular DLE is a rather rare presentation. We report the case of a 42-year-old male patient who had been repeatedly mis-diagnosed and upon detailed dermatological workup was found to possess clinical, dermoscopic, and histopathological features of DLE. Our report focuses on the importance of dermoscopy as a useful point-of-care investigation to avoid delay, and thus related complications. It further suggests how fundus examination could prove helpful in identifying lupus-related fundus changes, and explores how to devise a suitable plan of treatment for such patients.

Discoid lupus erythematosus solely involving the eyelids: case report and literature review

BACKGROUND AND OBJECTIVE

The involvement of eyelids occurs in only 5-6% of patients with discoid lupus erythematosus (DLE), commonly with mucocutaneous lesions elsewhere. DLE solely involving the eyelids is relatively rare. This study aimed to describe the clinical features and treatments of all the reported cases of DLE with eyelid involvement as the only symptom.

METHODS

A systematic review was done of all the related literature published both in English and Chinese from May 1, 1984, to March 1, 2020. Only those cases of DLE solely involving eyelids were selected and summarized in two tables.

RESULTS

(i) DLE solely involving the eyelids is five times more likely to affect females than males. (ii) The majority of cases were presenting with unilateral eyelid involvement. Lower lids, especially both lower lids, were the most commonly affected locations. (iii) An erythematous plaque with scales is the most frequent manifestation. (iv) Approximately 22.9% of the cases had a positive antinuclear antibody (ANA) titer, and the speckled pattern was the most seen. For direct immunofluorescence (DIF), 94.4% of the performed cases showed positive results. (v) More than 85% of these cases showed an excellent response to treatment with oral antimalarials.

CONCLUSION

Awareness of this atypical presentation is important to avoid underdiagnosis of DLE solely involving the eyelids. A biopsy for both routine histology and DIF is critical for establishing the diagnosis.
