Tertiary Syphilis is the final stage of syphilis, a sexually transmitted infection caused by the bacterium Treponema pallidum. This stage can occur years after the initial infection if left untreated. It can lead to severe health complications affecting various organs, including the heart, brain, and nervous system. Symptoms of tertiary syphilis may include difficulty coordinating movements, paralysis, numbness, and cognitive issues. It can also cause gummas, which are soft tissue growths. Early diagnosis and treatment with antibiotics, such as penicillin, are crucial to prevent progression to this advanced stage.
