Cutaneous Lupus Erythematosus Presenting as Frontal Fibrosing Alopecia: Report of 2 Patients

Abstract

Frontal fibrosing alopecia represents a peculiar condition with a quasi-symmetrical, marginal scarring alopecia along the frontal and temporal hairline. The condition has been associated with further histopathologic and/or clinical evidence of lichen planopilaris. Since its emergence with the original report of Kossard in 1994, frontal fibrosing alopecia has been recognized to be associated with a number of comorbidities, including lupus erythematosus. So far, respective case reports and case series have given account of frontal fibrosing alopecia with the histopathologic features of lichen planopilaris associated or overlapping with lupus erythematosus. In contrast, we present cases of histopathologically proven cutaneous lupus erythematosus presenting as frontal fibrosing alopecia with a good response to the respective treatment with oral hydroxychloroquine and/or intralesional triamcinolone acetonide.
