Summary
Scalp rosacea, or red scalp disease, is an inflammatory condition often misdiagnosed. Early recognition and management are key, as it has a favorable prognosis and does not cause scarring alopecia.
Area of Science:
- Dermatology
- Inflammatory skin diseases
Background:
- Scalp rosacea (red scalp disease) is an underrecognized inflammatory dermatosis.
- It presents with erythema, scaling, and papules, often misdiagnosed due to overlapping symptoms with other scalp conditions.
- Standardized diagnostic criteria and therapeutic guidelines are lacking.
Purpose of the Study:
- To review current evidence on scalp rosacea.
- To improve recognition and clinical management of this condition.
Main Methods:
- Literature review synthesizing current evidence.
- Analysis of clinical presentation, pathogenesis, diagnostic tools (trichoscopy, histopathology), differential diagnosis, and treatment.
Main Results:
- Scalp rosacea involves diffuse erythema, scaling, vascular alterations, and papules/pustules.
- Pathogenesis is multifactorial, including immune dysregulation and environmental factors.
- Trichoscopy and histopathology aid diagnosis, showing vascular ectasia and perifollicular inflammation.
- Management involves therapies similar to facial rosacea, with oral tetracyclines as first-line.
Conclusions:
- Scalp rosacea is a distinct entity requiring improved diagnostic and therapeutic approaches.
- Early identification and management lead to a favorable prognosis without permanent hair loss.
