What are the treatment options for a lump on the perineum?

A lump on the perineum—the area between the genitals and anus—is often caused by infections (such as abscesses or cysts), abnormal tissue growths (benign or malignant), or congenital conditions present from birth. Common culprits include Bartholin's cysts, pilonidal cysts, sebaceous cysts, and skin infections. Treatment varies based on the underlying cause and may include antibiotics, warm compresses, drainage procedures, or surgical removal.

Because a perineal lump can stem from many different conditions—some minor, others requiring prompt medical attention—identifying the likely cause early is key to getting the right care. Take a free, instant, online symptom check to better understand what may be causing your lump and confidently plan your next steps.

Explanation

A perineal lump (a small bump in the area between the anus and the genitals) may have several causes. For example, it could be an abscess that forms due to a bacterial infection. In such cases, antibiotics and a procedure called "incision and drainage" may be needed to clear the infection. Sometimes, the lump might be a benign growth resulting from congenital issues or rare conditions, such as ectopic breast tissue, where tissue normally found in another area is present in the perineum. If the lump is not causing symptoms, doctors might simply keep an eye on it with regular follow-ups. However, if it causes pain, grows larger, or raises concerns about its nature, surgical removal may be recommended. Evaluation typically starts with a physical exam, and further tests like imaging or a biopsy might be performed to determine the exact cause.
