Dupuytren, Ledderhose, and Peyronie Diseases After Primidone Use For Essential Tremor.

INTRODUCTION: Dupuytren, Ledderhose, and Peyronie diseases are chronic fibrotic conditions related to progressive fibrosis of the palmar fascia, plantar fascia, and tunica albuginea, respectively. These conditions have been associated with antiepileptic drug use, mainly phenobarbital and primidone. CASE REPORT: A 71-year-old man developed simultaneous Dupuytren, Ledderhose, and Peyronie diseases after primidone use for essential tremor. CONCLUSIONS: There are a few reports associating barbiturate use to connective tissue disorders, and some suggest that drug withdrawal may result in a better prognosis. Therefore, physicians must be aware of such adverse events when caring for patients on long-term barbiturate use.
