Rosacea is NOT a recognized subtype of the condition. Which option does NOT belong as a rosacea subtype?

• A. Erythematotelangiectatic
• B. Papulopustular
• C. Phymatous
• D. Seborrheic dermatitis

Answer: (D)

Seborrheic dermatitis does not belong because rosacea subtypes describe patterns of facial inflammation and vascular changes specific to rosacea, such as persistent redness with visible blood vessels, papules and pustules, or tissue thickening. The recognized rosacea subtypes include erythematotelangiectatic rosacea (redness and visible vessels), papulopustular rosacea (inflammatory bumps on a red base), and phymatous rosacea (skin thickening, often nasal). Seborrheic dermatitis is a separate inflammatory skin condition characterized by greasy scales and flaky dermatitis, often in seborrheic areas like the scalp and eyebrows, and is not considered a rosacea subtype.
