Easy as PIE (Postinflammatory Erythema).
BACKGROUND
No term exists to date describing the phenomenon of pink-to-red discoloration after an inflammatory acne lesion.


OBJECTIVE
To introduce new terminology into the dermatology literature to describe erythema often seen after inflammatory acne vulgaris and to present a treatment option for this type of erythema.


METHODS
New terminology describing erythema after inflammatory acne is addressed, and a treatment option for postinflammatory erythema is presented.


RESULTS
Postinflammatory erythema is a new, accurate descriptor of erythema that occurs after inflammatory acne. Additionally, pulsed dye laser treatment improved postinflammatory erythema in the authors' patients.


CONCLUSIONS
This paper only presents anecdotal cases.


CONCLUSIONS
The addition of postinflammatory erythema to the dermatology literature may facilitate accurate communication among providers and direct laser treatment for postinflammatory erythema.
