[Cogan syndrome or sarcoidosis?].

INTRODUCTION

The Cogan's syndrome is characterized by the association of vestibulo-auditory dysfunction, non syphilitic interstitial keratitis or another significant inflammatory eye lesion. Some authors consider this disease as a vasculitis, because it is frequently associated with systemic manifestations. Based on Cogan's diagnostic criteria, Cogan's syndrome may be part of other systemic diseases, as polyarteritis nodosa or Wegener's granulomatosis.

EXEGESIS: We report the case of a patient who presented with a Cogan's syndrome and developed further sarcoidosis.

CONCLUSION

If Cogan's syndrome is characterized as systemic disease because of its association with aortitis or other vasculitis, on the other hand, clinical presentation may be part of many other systemic diseases.
