Rosacea

Rosacea is a chronic, relapsing inflammatory skin condition primarily affecting the central face. It is characterized by vasodilation, erythema, papules, pustules, and in severe cases, hypertrophy of sebaceous glands. While the exact cause remains multifactorial, it is considered a disorder of neurovascular dysregulation and innate immune dysfunction.

The etiology involves a complex interplay of genetics, environmental triggers, and microbiome dysbiosis. Key factors include hyper-responsiveness of the cutaneous vascular system, dysregulation of the innate immune system (specifically toll-like receptor 2), and the proliferation of Demodex folliculorum mites in the pilosebaceous units.

Rosacea involves persistent vasodilation and increased permeability of dermal blood vessels. Chronic inflammation is driven by the overexpression of cathelicidins (antimicrobial peptides) in response to external triggers. Neurogenic inflammation plays a role, as sensory nerve fibers release neuropeptides like substance P, leading to flushing and erythema.

Rosacea typically affects adults aged 30 to

1. It is most prevalent in individuals of Northern European descent. Women are affected more frequently than men, though men often develop more severe, hypertrophic forms (e.g., rhinophyma).

• Fair skin (Fitzpatrick types I-II)
• Family history
• Smoking
• Chronic UV exposure
• Hormonal changes
• Emotional stress

A. Early Symptoms

• Episodic flushing


• Stinging or burning sensation


• Mild persistent redness B. Common Symptoms


• Persistent central facial erythema


• Papules and pustules


• Telangiectasias (visible vessels) C. Advanced Symptoms


• Phymatous changes (skin thickening/bulbous nose)


• Ocular involvement (gritty eyes, blepharitis)


• Persistent edema D. Emergency Symptoms


• Sudden severe vision loss


• Periorbital cellulitis signs (fever, warmth, spreading redness)

Inspection reveals centrofacial erythema, telangiectasias, and inflammatory lesions. Palpation may detect skin thickening or plaque formation. Ocular exam may show episcleritis or conjunctivitis.

A. Clinical Assessment: Primarily diagnosis based on morphological patterns.
B. Laboratory Testing: Generally not required.
C. Imaging Studies: Generally not indicated.
D. Functional Tests: None.
E. Biopsy Findings: Non-specific; perivascular infiltrate with lymphocytes and histiocytes.
F. Genetic Testing: Not indicated.
G. Differential Diagnosis: Acne vulgaris, lupus erythematosus, seborrheic dermatitis.

Demodex count
Type: Microscopic skin scraping
Purpose: To assess mite density
Expected Findings: >5 mites per square centimeter
Interpretation: High density supports diagnosis in resistant cases.

None standard. High-frequency ultrasound may be used in clinical research to measure skin thickness in rhinophyma.

• Acne vulgaris (distinguished by lack of comedones in rosacea)
• Systemic Lupus Erythematosus (distinguished by ANA positivity)
• Seborrheic Dermatitis (distinguished by greasy, yellow scaling)

Permanent skin thickening, ocular scarring (keratitis), psychological distress.

A. Lifestyle Modifications: Avoid triggers (spicy food, alcohol, sun, extreme temperatures).
B. Preventive Measures: Daily broad-spectrum SPF 30+.
C. Medical Treatment

• Topical: Metronidazole, Azelaic acid, Ivermectin cream.


• Systemic: Doxycycline (sub-antimicrobial dose), Isotretinoin (severe cases).

Chronic condition; management allows for long-term remission, though complete "cure" is rare.

Sun protection and avoidance of identified personal triggers.
