What Could Cause a Lump under the Skin in the Pubic Area, and How Is It Treated?

A lump under the skin in the pubic area can be caused by benign issues like a cyst or a lipoma, an infection, or even swollen veins in pregnancy. The treatment depends on what is causing the lump and may range from monitoring it to removing it with a simple procedure.

Explanation

There are several reasons you might notice a lump under the skin in your pubic area. One common cause is a cyst, such as a dermoid cyst, where skin tissues get trapped and form a small, benign sac under the skin. Another possibility is a lipoma, which is a soft, harmless lump made of fat. Infections or swollen lymph nodes could also create lumps, typically accompanied by redness, pain, or warmth. In pregnant individuals, swollen veins (varices) in the round ligament area might also be felt as a lump. Treatment options depend on the cause and your symptoms. If the lump is not causing any discomfort, a doctor might simply watch it over time. However, if it becomes painful, grows, or shows signs of infection (like redness or warmth), treatment might be necessary. This could include medications, such as antibiotics if there is an infection, or a minor surgical procedure to remove the cyst or lipoma. It is a good idea to have any new lump checked by a healthcare provider to determine its cause and the best way to manage it.
