Common Presentations in the Different Stages of Syphilis Stage Primary Secondary Latent Tertiary Presentation Painless ulcer at of inoculation Regional lymphadenopathy Rash, especially on the palms and soles Mucous membrane lesions Malaise, fever, sore throat, headache, arthralgia, generalized lymphadenopathy Syphllitic meningitis with cranial nerve palsies, iritis with anterior uveitis Asymptomatic, detectable by abnormal serologic test results Cardiovascular syphilis aortic aneurysm, aortic regurgitation, nonatherosclerotic coronary artery disease Gummatous syphilis Neurosyphilis Asymptomatic neurosyphilis Tabes dorsalis: lightning pains, pupillary abnormalities, ataxia, lower extremity reflex abnormalities, incontinence General paresis: dementia with slurred speech, pupillary abnormalities, reflex abnormalities, tremor seizures
Classification of Syphilis Early infectious syphilis Primary syphilis An often painless anogeniyal chancre(ulcer) with dependent lymphadenopathy Can persist into the secondary stage Incubation period of 9-90d but usually 3-4 wks Secondary syphilis Multisystem involvement due to bacteraemia, resulting in generalised rash (+/- condylomata lata), and lymphadenopathy, systemic malaise and fever, buccal and genital mucosal erosions; may also cause patchy alopecia, hepatitis, meningitis, cranial nerve palsies,uveitis, periostitis and glomerulonephritis 4-8 wks after appearance of chancre Early latent syphilis Late non-infectious syphilis Late latent syphilis Gummatous syphilis Neurosyphilis Cardiovascular syphilis From the end of the secondary stage to the end of a 1yr period after the appearance of chancre Positive serologic tests for syphilis but without symptoms or signs Classifled as infectious because relapse to the secondary stage is possible up to 1yr From the 1y point onwards Asymptomatic with positive serologic tests for syphilis Most untreated patients would remain in this stage Rare but described in patients recently co-infected with HIV; can be infiltrative or ulcerative Rare but rapid progress to this stage, described in patients co-infected with HIV; meningovascular, tabes dorsalis and general paresis Rare; aortic regurgitation or aneurysm, coronary ostiitis
