Sclerokeratouveitis and lens dislocation in a patient with genital ulcer: was the great imitator imitated?

Uveitis is the most common ocular manifestation of syphilis, while scleritis is rare. A case of nodular scleritis, peripheral keratitis and uveitis in a patient with genital ulcer is presented in this report. This patient had a clinical profile suggestive of syphilis, though the serology was negative for treponemal antibodies. Other possible differential diagnosis imitating syphilis are discussed.
