Summary
Darier disease, a genetic disorder affecting calcium channels, can manifest with skin lesions on extremities. This report details three cases of acral hemorrhagic Darier disease triggered by injury, showing good response to retinoid therapy.
Area of Science:
- Dermatology
- Genetics
- Calcium Channel Biology
Background:
- Darier disease is an inherited condition impacting calcium channel regulation due to gene mutations.
- It presents with diverse manifestations and inconsistent genotype-phenotype correlations.
- Acral hemorrhagic Darier disease specifically involves macules, papules, vesicles, or hemorrhagic blisters on extremities.
Observation:
- This study reports three new cases of acral hemorrhagic Darier disease.
- The onset of the disease in these cases was triggered by physical injuries.
- Histopathology confirmed characteristic features like dyskeratosis and suprabasal acantholysis with hemorrhagic lacunae.
Findings:
- Acral hemorrhagic Darier disease can be precipitated by injuries.
- The three reported cases demonstrated a positive response to retinoid therapy.
- This suggests a potential therapeutic avenue for this specific Darier disease subtype.
Implications:
- Understanding injury-induced Darier disease can improve diagnosis and management.
- Retinoid therapy shows promise for acral hemorrhagic Darier disease.
- Further research into genotype-phenotype correlations and treatment responses is warranted.
