Cutis marmorata occurs due to exposure to:
Show Hint
A marbled skin pattern in a newborn that disappears on rewarming.

- Cold temperature
- Dust
- Hot temperature
- Humidity
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Recall that cutis marmorata is a benign newborn finding rather than a disease. The clue word is marbled, reticulated skin.
Step 2: The change is purely temperature driven: lowering the ambient temperature triggers an unstable vasomotor reaction in cutaneous capillaries, with simultaneous dilatation and contraction of the superficial vessels.
Step 3: Because cold is the precipitant, simply warming the infant makes the mottling vanish, confirming the cause. Dust, heat and humidity are not associated with this reaction.
Step 4: Hence the exposure responsible is cold temperature.\[\boxed{\text{Cold temperature}}\]
