AbstractUncommon forms of syphilis exist, among which neurosyphilis, otosyphilis, and ocular syphilis are included. Neurosyphilis is the infection of the central nervous system caused by Treponema pallidum. The clinical manifestations of neurosyphilis are diverse and include early, late, and atypical forms. Syphilis can affect virtually any ocular structure and can occur at any stage of the disease, as well as otosyphilis. The diagnosis of these conditions is often challenging. However, it is important to consider them as a differential diagnosis, as most of these clinical manifestations are reversible with appropriate antibiotic treatment. A case series study of patients diagnosed with neurosyphilis, otosyphilis, and ocular syphilis, who were admitted to a tertiary-level hospital, is here presented: syphilitic meningitis with cranial nerve involvement, and seizures (case 1), ocular syphilis (case 2), general paresis (case 3), and tabes dorsalis (case 4). Half of the patients presented bilateral sensorineural hearing loss; and also half of the patients had reactive VDRL in cerebrospinal fluid. All were treated with aqueous penicillin G, and in two of these cases, ceftriaxone was chosen to complete ambulatory treatment. One patient had an unfavorable outcome and died (case 1); another was lost in follow-up (case 4); one completely resolved his symptoms (case 2); and another one experienced symptom relapse six months after treatment (case 3).
