Chronic Cutaneous Lupus Erythematosus in a Blaschkoid Pattern over Face

Area of Science:

• Dermatology
• Autoimmune Diseases

Background:

• Chronic cutaneous lupus erythematosus (CCLE) is an autoimmune condition affecting the skin.
• Linear lesions following Blaschko lines are an uncommon presentation of CCLE.
• This pattern is particularly rare in adult patients.

Purpose of the Study:

• To report a rare case of CCLE presenting with linear lesions along Blaschko lines.
• To emphasize the unusual late-onset and facial predilection in this adult patient.
• To contribute to the understanding of rare CCLE variants.

Main Methods:

• Case report detailing clinical presentation and diagnostic findings.
• Review of relevant literature on Blaschko linear CCLE.

Main Results:

• The patient presented with chronic, linear skin lesions on the face.
• The lesions followed Blaschko lines, a rare pattern for CCLE.
• The onset of symptoms occurred later in adulthood.

Conclusions:

• This case underscores the variability in CCLE presentation.
• Linear Blaschko-linear CCLE can occur in adults, albeit rarely.
• Awareness of this variant is important for accurate diagnosis.
