Summary
Red nail lunulae are a rare finding in alopecia areata. This study observed two patients with severe alopecia areata who developed red lunulae, which later resolved into Beau
Area of Science:
- Dermatology
- Nail Diseases
- Hair Loss Disorders
Background:
- Alopecia areata is an autoimmune condition causing patchy hair loss.
- Nail changes can occur in alopecia areata, but red lunulae are exceptionally rare.
Observation:
- Two patients (30-year-old female, 61-year-old male) with severe alopecia areata were studied.
- Both patients presented with red lunulae shortly after the onset of hair loss.
Findings:
- Red lunulae developed a few weeks post-acute hair loss.
- The red discoloration gradually faded.
- Resolution of red lunulae was followed by the appearance of horizontal fissures (Beau's lines).
Implications:
- This observation expands the spectrum of nail abnormalities associated with alopecia areata.
- Red lunulae may serve as a transient clinical sign in severe alopecia areata.
- Further research is needed to understand the pathogenesis of red lunulae in this condition.
