About nasal syphilis the following is true:

Nasal syphilis may be: Acquired: - Primary, e.g. chancre in vestibule - Secondary, e.g. simple rhinitis, crusting and fissuring leading to atrophic rhinitis - Teiary, e.g. Gumma leads to septal perforation and saddle nose deformity (due to collapse of nasal bridge) Congenital: - Early (first 3 months): Presenting as snuffles, purulent nasal discharge, fissuring excoriation. - late (around pubey): Gumma in septum and other stigmatas. Teritary syphilis is a common association: primary and secondary syphilis are rare association in nasal syphilitis. Septal perforation occurs in bony pa in case of syphilis.
