Abstract
BACKGROUND

Lidocaine/prilocaine (EMLA) cream is a local anesthetic that is applied to the skin or mucosa during painful therapeutic procedures with few reported side effects.

CASE SUMMARY

Here, we report the use of dermatoscopy to identify a case of erythema with purpura, a rare side effect, after the application of 5% EMLA cream.

CONCLUSION

We conclude that erythema with purpura is caused by irritation and toxicity associated with EMLA, but the specific mechanism by which the toxic substance affects skin blood vessels is unclear. In response to this situation and for cosmetic needs, we recommend tranexamic acid, in addition to routine therapy, to prevent changes in pigmentation in patients with dermatitis.

Keywords: Erythema, Purpura, Lidocaine/prilocaine, Dermatoscope, Toxic reaction, Case report

Core Tip: We report erythema and purpura under dermatoscope induced by lidocaine/prilocaine (EMLA) in a female in the process of cosmetic dermatology. We analyzed the possible etiology and pathology of the dermatitis specifically. This is the first time to share this case report, of which the content has not been published, nor has submitted for publication elsewhere. We expect this report will draw more attention to the use of EMLA especially from dermatologist for cosmetic therapy.
