A seborrheic keratosis – a benign, wart-like growth that’s common with aging and sun-exposed skin. It often appears brown, black, or light tan and has a waxy or scaly appearance.
A mole (nevus) – especially if it’s raised or crusty.
A keratoacanthoma – a low-grade skin tumor that can resemble squamous cell carcinoma.
A possible actinic keratosis – a precancerous lesion caused by sun damage that may feel rough or scaly.
Doesn't look like actinic keratosis to me......I have a lot of those patches
However, if the spot has changed in size, shape, color, or started bleeding, itching, or crusting, it’s very important to get it checked by a dermatologist.
