Coexistence of Chronic Cutaneous Lupus Erythematosus and Frontal Fibrosing Alopecia

The document described a patient with chronic lichenoid lupus erythematosus who also exhibited clinical, histopathological, and dermoscopic features of frontal fibrosing alopecia (FFA). Lupus erythematosus is a chronic, relapsing disease that can cause various types of alopecia, including cicatricial alopecia from discoid lesions on the scalp. FFA is characterized by frontotemporal hairline recession and eyebrow loss and is histopathologically similar to lichen planopilaris. The coexistence of chronic cutaneous lupus erythematosus and FFA in the patient was notable, as the literature did not previously document FFA as a clinical manifestation of lupus.
