adj. That which resembles acne. Also written acneiform.
The term acneform is rarely used except in the phrases acneform eruption, acneform rash, and acneiform dermatoses. While all of these are in common use in medical jargon, there is no consensus on whether the spelling of acneform or acneiform is better.
Acneform conditions may be caused by acne vulgaris, rosacea, folliculitis, and perioral dermatitis, among others.
