Type 1 Segmental Darier Disease: Case Report and Discussion of the Treatment Options

Area of Science:

• Dermatology
• Genetics
• Molecular Biology

Background:

• Darier disease is a rare autosomal dominant genodermatosis caused by mutations in the ATP2A2 gene, which encodes the endoplasmic reticulum Ca2+-ATPase.
• This genetic defect impairs intercellular adhesion, leading to characteristic skin lesions.
• The condition typically presents with keratotic papules in seborrheic areas, exacerbated by heat, sun, and friction.

Observation:

• Unilateral segmental Darier disease is a rare variant presenting as localized erythematous keratotic papules.
• This case report focuses on a specific instance of type 1 segmental Darier disease.
• The patient's presentation and disease progression were closely monitored.

Findings:

• The study details the clinical presentation of type 1 segmental Darier disease.
• Genetic analysis confirmed the underlying mutation responsible for the condition.
• The report discusses the specific dermatological and potential nail/mucosal manifestations observed.

Implications:

• Understanding the genetic basis and clinical spectrum of Darier disease is crucial for accurate diagnosis.
• This case highlights the variability of segmental Darier disease presentation.
• Effective management strategies and treatment options for Darier disease are discussed, offering insights for clinical practice.
