Which of the following findings is MOST characteristic of immersion in cold water for an extended period before death?

Explanation

## Cold Water Immersion: Characteristic Postmortem Signs **Key Point:** Cutis anserina (goose skin) is a pathognomonic sign of death in cold water, resulting from postmortem contraction of arrector pili muscles in response to cold, producing a characteristic bumpy appearance on the skin. ### Cutis Anserina (Goose Skin) **Definition:** Postmortem appearance of the skin resembling that of a plucked goose, with small elevations at the bases of hair follicles. **Mechanism:** 1. Cold exposure causes sustained contraction of arrector pili muscles 2. Muscles remain contracted even after death 3. Creates visible bumps around each hair follicle 4. Appears within minutes to hours of cold water immersion ### Other Signs of Cold Water Immersion | Sign | Mechanism | Timing | |------|-----------|--------| | **Cutis anserina** | Arrector pili contraction | Minutes to hours | | **Pallor mortis** | Intense peripheral vasoconstriction | Immediate | | **Reduced livor mortis** | Vasoconstriction limits blood pooling | Early | | **Delayed rigor mortis** | Cold slows metabolic processes | 6–12 hours or more | | **Preserved tissues** | Cold inhibits bacterial growth | Days to weeks | **High-Yield:** Cutis anserina is virtually pathognomonic for death in cold water and is a valuable forensic indicator of the environment of death. **Clinical Pearl:** Cold water immersion slows decomposition dramatically; bodies may remain well-preserved for weeks or months, facilitating identification and autopsy findings. **Mnemonic:** **COLD WATER** → **C**utis anserina, **O**ther signs of vasoconstriction, **L**ate rigor mortis, **D**elayed decomposition.
