**Question:** Features of congenital syphilis are-
a) Snuffles is late manifestation
b) Perforation in cartilaginous part of nose
c) Mulberry molar
d) Saddle nose deformity

**Core Concept:** Congenital Syphilis is a severe form of syphilis that affects infants born to infected mothers. It is caused by the Treponema pallidum bacterium and presents with a range of symptoms depending on the stage of infection.

**Why the Correct Answer is Right:**

The correct answer, **D) Saddle nose deformity**, is related to the late manifestations of congenital syphilis. In advanced stages, the disease can lead to destructive cartilage necrosis, causing damage to the nasal cartilage and resulting in a "saddle nose" deformity. This is a severe complication of congenital syphilis and is not present in the other options.

**Why Each Wrong Option is Incorrect:**

A) **Snuffles:** Snuffles is a term used to describe early manifestations of congenital syphilis in infants, typically presenting within the first six months of life. It is not a late manifestation and should not be selected as the correct answer.

B) **Perforation in cartilaginous part of nose:** Perforation in the cartilaginous part of the nose is also not a late manifestation of congenital syphilis and should not be selected as the correct answer.

C) **Mulberry molar:** This option refers to a dental abnormality in early childhood, which is not a late manifestation of congenital syphilis. It should not be selected as the correct answer.

**Clinical Pearl:**

It is crucial for healthcare professionals, especially obstetricians and pediatricians, to remain vigilant about the potential for congenital syphilis, as timely diagnosis and treatment can prevent severe complications like saddle nose deformity.

In summary, congenital syphilis presents with a range of symptoms depending on the stage of infection. The correct answer, Saddle nose deformity, is a severe complication that occurs in the late stages of congenital syphilis, while the incorrect answers (Snuffles, perforation in cartilaginous part of the nose, mulberry molar) are early manifestations of the disease that are not relevant to the late manifestations.
