Rosacea is characterised by all of the following EXCEPT:
- A Presence of open and closed comedones as primary lesions ✓
- B Centrofacial distribution of erythema and telangiectasia
- C Ocular involvement (blepharitis, keratitis) in a subset of patients
- D Phymatous changes (rhinophyma) in severe cases
Correct answer: A. Presence of open and closed comedones as primary lesions
Explanation
Rosacea is characterised by facial flushing, persistent centrofacial erythema, telangiectasia, inflammatory papules and pustules WITHOUT comedones — the absence of comedones is a key feature distinguishing rosacea from acne vulgaris. Ocular rosacea (blepharitis, conjunctivitis, keratitis) occurs in up to 50% of patients. Phymatous rosacea (rhinophyma — sebaceous hyperplasia of the nose) represents the granulomatous subtype. The presence of comedones should prompt reconsideration of the diagnosis.
