Petechial and purpuric eruption induced by lidocaine/prilocaine cream: a rare side effect.

Lidocaine/prilocaine cream is a topical anesthetic commonly used in pediatric and dermatologic practice to obtain local anesthesia. Common side effects include: transient skin blanching, erythema, urticaria, allergic contact dermatitis, irritant contact dermatitis, and hyperpigmentation.

Transepidermal elimination is a mechanism by which altered dermal extracellular material is discharged through the epidermis. Perforating elastosis is a rare disease characterized by the transepidermal elimination of abnormal elastic fibers. Clinically it manifests as skin-colored keratotic papules that may coalesce and form arcuate or serpiginous plaques.
