The patient may also have syphilitic meningitis, chorioretinitis, hepatitis, nephritis (immune complex type), or periostitis. The secondary lesions also subside spontaneously.

Contagious lesions may recur within 3-5 years after infection, but thereafter the individual is not infectious.Ref: Jawetz; 27th edition; Page no: 324
