Tattoo is not visible on autopsy. But the presence of tattoo was informed by relative. What is the next site to check?
**Core Concept**
The visibility of tattoos can be affected by various factors, including the location, depth, and type of ink used. Tattoos are more likely to be visible on areas with thin skin, such as the arms and legs, but may be less visible on areas with thicker skin, such as the torso.
**Why the Correct Answer is Right**
The correct site to check for an invisible tattoo is the **scalp**, as it has a unique characteristic of having a thin layer of skin that is easily penetrated by tattoo ink. This makes it a reliable site for detecting tattoos that are not visible on other parts of the body. The scalp's skin is also relatively thin and has a rich blood supply, which can help to identify the presence of tattoo ink.
**Why Each Wrong Option is Incorrect**
* **Option A:** The palms of the hands are not a reliable site to check for invisible tattoos, as the skin is too thick and the ink may not be visible.
* **Option B:** The soles of the feet are also not a reliable site, as the skin is too thick and the ink may not be visible.
* **Option C:** The nails are not a reliable site to check for invisible tattoos, as the ink may not penetrate the nail bed.
**Clinical Pearl / High-Yield Fact**
The scalp is a reliable site to check for invisible tattoos due to its thin skin and rich blood supply, making it a useful location for forensic examination.
**Correct Answer:** C.
