Condyloma latum, ocular involvement, snail track ulcers, greyish membrane covering surface, joint involvement.
Latent syphillis

Gummata - indurated or ulcerated
Complications: cardiovascular syphillis, neurosyphillis, Argyll Robertson pupils
Congenital syphillis
Mulberry molars
Hutchinson incisors
Open bite
Diagnosis of syphillis
Serological tests
Management of syphillis
