Perianal Bumps: Possible Causes and Treatments - Surgery

There is a lump near the anus, close to the perineum?


Hello, Dr.
Ko.
I have noticed a small bump that resembles a pimple located between my anus and perineum.
It started as a tiny bump, but the next day it seemed to grow a little larger and rounder.
It is painful when pressed, and there appears to be a white spot on it.
Could this be an anal fistula or a sebaceous cyst? (It is not located directly on the anus.)

If the lump is located a distance away from the anus, it could possibly be a sebaceous cyst.
However, if it is near the vaginal opening, it may be an inflammation of the Bartholin's gland.
If there is no discomfort or if it is not continuously enlarging, you can choose to monitor it.
Otherwise, it is advisable to consult a physician for examination and treatment to avoid any delay in addressing the condition.

More Info


When it comes to perianal bumps, there are several potential causes, and understanding these can help you determine the best course of action. Based on your description, the bump you are experiencing could be a variety of conditions, including a perianal abscess, a sebaceous cyst (also known as an epidermoid cyst), or even a pilonidal cyst. Each of these conditions has distinct characteristics and treatment options.

1. Perianal Abscess: This is a collection of pus that can occur near the anus, often resulting from an infection of the anal glands. Symptoms typically include pain, swelling, and sometimes fever. The bump may feel tender and could have a white or yellow point, indicating that it may be ready to drain. If this is the case, it is crucial to seek medical attention, as abscesses often require drainage to prevent further complications.

2. Sebaceous Cyst: These are non-cancerous lumps beneath the skin, often filled with a thick, oily substance. They can occur anywhere on the body, including the perianal area. Sebaceous cysts are usually painless unless they become infected, in which case they can become red, swollen, and tender. If the cyst is not causing significant discomfort or other symptoms, it may not require immediate treatment, but monitoring it for changes is advisable.

3. Pilonidal Cyst: This type of cyst typically occurs near the tailbone but can also appear in the perianal region. It often contains hair and skin debris and can become infected, leading to pain and swelling. Treatment may involve drainage and, in some cases, surgical removal.

Given that you mentioned the bump is painful and has a white point, it is essential to consider the possibility of an infection, which could indicate an abscess. In such cases, self-care measures may provide temporary relief, but they are not a substitute for professional medical evaluation. Here are some self-care tips you can consider while awaiting a medical appointment:
- Warm Compresses: Applying a warm compress to the area can help reduce pain and promote drainage if there is an abscess. Do this several times a day for 15-20 minutes.

- Over-the-Counter Pain Relief: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or acetaminophen can help alleviate pain and reduce inflammation.

- Hygiene: Keeping the area clean and dry is crucial. Gently wash the area with mild soap and water, and avoid using harsh chemicals or fragrances that could irritate the skin.

- Avoid Squeezing: Do not attempt to squeeze or pop the bump, as this can worsen the infection or lead to further complications.

- Monitor Symptoms: Keep an eye on the bump for any changes in size, color, or pain level. If you notice worsening symptoms, such as increased redness, swelling, or fever, seek medical attention promptly.

While these self-care measures may provide temporary relief, it is important to consult a healthcare professional for a definitive diagnosis and appropriate treatment. They may perform a physical examination and, if necessary, imaging studies or laboratory tests to determine the exact nature of the bump. Depending on the diagnosis, treatment options may include drainage, antibiotics, or surgical removal.

In summary, while the bump you are experiencing could be a perianal abscess, sebaceous cyst, or pilonidal cyst, it is crucial to seek medical advice for an accurate diagnosis and appropriate treatment. Self-care measures can help alleviate discomfort in the meantime, but professional evaluation is essential to prevent complications and ensure proper management of the condition.

If it is an anal canal issue, you should be able to feel a firm subcutaneous tissue between the two areas. Based on your description, it seems more like a small abscess, likely a benign lesion such as an epidermal inclusion cyst. It may be advisable to try antibiotics first.
