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. The authors report a petechial and purpuric reaction after the application of lidocaine/prilocaine cream. This is a rare side effect, since to our knowledge only few case reports have been documented in literature.
