What condition may lead to mottling of the skin?

Mottling of the skin is often associated with shock, as it indicates poor circulation and inadequate blood flow to the tissues. When a person is in shock, their body prioritizes blood supply to vital organs, which can lead to decreased perfusion in the extremities and skin. This results in a mottled appearance, characterized by irregular patches of discoloration.

In contrast, while infections, burns, and allergic reactions can also have varying impacts on skin appearance and health, they typically do not lead to mottling in the same manner as shock. Infections may cause redness, swelling, or warmth; burns can lead to blistering or charred skin; and allergies usually produce rashes or hives. Mottling is a distinct sign related specifically to compromised circulation, especially in the context of shock.
