A small lump in this area might be something benign, like extra soft tissue or a lipoma, which is a harmless fatty growth. Sometimes it could be an accessory scrotum, which is extra scrotal tissue that is rare but usually not dangerous. However, other times, a lump like this could be a sign of an infection or even a soft tissue tumor that needs more investigation. Because many conditions can cause a lump, you can start by using a free symptom checker to help identify possible causes, but it is essential to have a doctor look at it for proper evaluation. The healthcare professional may perform a physical exam and might use imaging tests like an ultrasound if needed to find out what the lump is. This evaluation helps rule out any serious problems and ensures that you receive the proper treatment if needed. Even if the lump does not hurt or change, getting it checked early is the best way to be sure everything is okay.
