In brief: X-ray finding
Punched out lesions are an x-ray find that explains the bony destruction caused by gout and other arthritic conditions.
It is the absence of normal bone in an irregular pattern around a joint/capsule interface.

In brief: Uric acid
When uric acid goes into the joint and precipitates, it forms gouty tophi which can eat away at bone causing punched out lesions.
