Rosacea & Hidradenitis Suppurativa

Key points

• Rosacea: facial flushing, erythema, telangiectasia, papules/pustules (NO comedones) — middle-aged; triggers: alcohol, spicy food, temperature.
• Rhinophyma: sebaceous hyperplasia of the nose in long-standing rosacea.
• Management: avoid triggers, topical metronidazole/azelaic acid, oral tetracyclines for papulopustular disease; ocular rosacea needs review.
• Hidradenitis suppurativa: painful nodules/abscesses/scarring in axillae/groins (apocrine areas); associations — smoking, obesity; management: topical/oral antibiotics, surgery, biologics.
• Rosacea lacks comedones — distinguishes it from acne.
