title: [Pronounced symptom deterioration in complex regional pain syndrome type II after isolated application of a highly concentrated capsaicin patch. A case report].
abstract: Topical 8 % capsaicin is an established therapeutic option for the treatment of peripheral neuropathic pain. In accordance with the internationally accepted definition, complex regional pain syndrome (CRPS) type II is a form of neuropathic pain so that capsaicin plasters represent a treatment option. However, for the treatment of CRPS it is recommended that painful stimuli should be avoided but capsaicin induces a strong nociceptive stimulation and so its use is at present controversial. We report on the course of such an application in a patient who developed CRPS type II with intractable neuropathic pain after hallux surgery. As a result of a single treatment with capsaicin a pronounced recurrence developed with central nervous symptoms.
