There are bump-like lesions between the anus and the scrotum?


Hello, doctor.
I would like to inquire about a bump that has recently appeared in the area between my anus and scrotum.
It resembles a pimple and causes slight pain, similar to the discomfort of acne on my face.
This has been ongoing for a while.
What could this be?

It could be a sebaceous cyst, which has a similar cause to acne.
However, a proper diagnosis still requires examination by a physician.
It is important to avoid infection, and if there is redness, swelling, or pain, you should seek medical attention immediately.

More Info


It sounds like you are experiencing a painful bump located between the anus and scrotum, which can be concerning. This area, known as the perineum, can be susceptible to various conditions that may cause bumps or lesions. Here are some potential causes for the bump you are describing:
1. Folliculitis: This is an inflammation of the hair follicles, which can occur in the perineal area. It often presents as small, red bumps that can be painful or itchy. Folliculitis can be caused by bacterial infections, irritation from shaving, or friction from clothing.

2. Pilonidal Cyst: This is a cyst that can occur near the tailbone but may also develop in the perineal area. It can become infected and painful, leading to the formation of a bump. Symptoms may include redness, swelling, and discharge.

3. Sebaceous Cyst: These are non-cancerous lumps that can form under the skin due to blocked sebaceous glands. They are usually painless but can become inflamed or infected, leading to discomfort.

4. Hemorrhoids: While typically associated with the rectal area, hemorrhoids can sometimes cause discomfort and may be mistaken for bumps in the perineal region. They can be internal or external and may cause pain, itching, or bleeding.

5. Genital Warts: Caused by the human papillomavirus (HPV), genital warts can appear as small bumps in the genital area, including the perineum. They may be itchy or painful.

6. Infections: Various infections, including sexually transmitted infections (STIs), can cause bumps or lesions in the genital area. Conditions such as herpes can lead to painful sores.

7. Skin Conditions: Conditions like eczema or psoriasis can also affect the genital area, leading to bumps or irritation.

Given that the bump has been persistent and is causing discomfort, it is essential to seek medical evaluation. A healthcare provider can perform a physical examination and may recommend tests to determine the exact cause of the bump. Treatment will depend on the underlying condition and may include topical medications, antibiotics, or other interventions.

In the meantime, here are some general care tips:
- Avoid Irritation: Wear loose-fitting clothing and avoid tight underwear to reduce friction and irritation in the area.

- Maintain Hygiene: Keep the area clean and dry. Gently wash with mild soap and water.

- Avoid Picking: Do not squeeze or pick at the bump, as this can lead to infection or worsen the condition.

In conclusion, while there are several potential causes for the painful bump between the anus and scrotum, a proper diagnosis from a healthcare professional is crucial for effective treatment. If you experience any additional symptoms, such as fever, increased pain, or changes in bowel habits, seek medical attention promptly.
