Dear Harvey,
From what you have described it appears that you have a lesion on the scrotal skin which is distinct and separate from the testicle itself. This may represent a sebaceous cyst( a swelling of an oil gland in the skin) or just a simple acne like lesion. These could potentially persist more than a few days and may eventually come to head and then pop open and drain. A testicular lesion ,on the other hand, is always cause for attention and should be attended to and evaluated right away. The primary concern in such case is testicular cancer.
Testicular cancer is a serious disease which should be evaluated and treated promptly. This is a highly treatable and curable disease, if caught early. It could otherwise be quite deadly. The peak age for testicular tumor is between ages of 15 to 34. It is more common in whites than blacks. It may present as a swelling or mass on one testicle ( and rarely on both) . This may be painless or sometimes painful. Regardless, any testicular or scrotal abnormality in a male should be evaluated by a physician , preferably a urologist, right away.
