[Anetoderma and lupus erythematosus. Study of 2 cases]

Area of Science:

• Dermatology
• Immunopathology
• Rheumatology

Context:

• Investigates the uncommon co-occurrence of anetoderma and lupus erythematosus (LE).
• Examines two distinct cases: secondary anetoderma with subacute LE and Schweninger Buzzi anetoderma with LE tumidus.
• Analyzes pathogenic mechanisms and characteristics of this rare dermatological association.

Purpose:

• To elucidate the pathological features and underlying mechanisms of the anetoderma and LE association.
• To identify key indicators present in affected skin tissues.
• To understand the role of vascular inflammation in the degradation of elastic fibers.

Summary:

• Presents two cases highlighting secondary anetoderma with subacute LE and Schweninger Buzzi anetoderma with LE tumidus.
• Identifies leucocytoplastic angitis and generalized loss of elastic fibers in the first case.
• Observes angitis and immunoglobulin deposits on elastic fibers in new lesions of the second case.
• Highlights leucocytoplastic angitis and immunoglobulin deposits on elastic fibers as consistent findings.
• Suggests angitis plays a crucial role in the disappearance of elastic fibers.

Impact:

• Provides insights into the pathogenesis of a rare dermatological condition.
• Enhances understanding of the interplay between autoimmune disease and connective tissue degradation.
• Contributes to the diagnostic criteria and potential therapeutic targets for associated conditions.
