Perianal mass


I have had an external anal lump for over a year, about the size of a grain of rice.
Sometimes it improves, but at times it becomes painful and appears white when it matures.
Once it matures, it automatically discharges pus and then blood.
Occasionally, there are blood streaks on my underwear, which is quite bothersome.
What should I do to resolve this issue?

Based on your description, it could be a skin sebaceous cyst or an anal abscess.
It is recommended that you visit a colorectal surgeon for evaluation and treatment as soon as it occurs to confirm the diagnosis and receive appropriate management.

More Info


External anal masses can be a source of discomfort and concern, particularly when they exhibit symptoms such as pain, discharge, or bleeding. Based on your description, it sounds like you may be dealing with an anal abscess or possibly a fistula, which can develop from an infection in the anal glands. Here’s a comprehensive guide on understanding and treating external anal masses.


Understanding External Anal Masses
1. Types of Anal Masses:
- Anal Abscess: This is a collection of pus that can form due to infection. It often presents as a painful, swollen area near the anus, which may drain pus or blood.

- Anal Fistula: This is a small tunnel that can develop between the anal canal and the skin near the anus, often resulting from a previous abscess. It may cause persistent drainage and discomfort.

- Hemorrhoids: Swollen blood vessels in the rectal area can also present as lumps and may cause bleeding, especially during bowel movements.

- Skin Tags: These are benign growths that can occur around the anal area and are usually painless.

2. Symptoms: The symptoms you describe—pain, white discharge, and occasional bleeding—are indicative of an infection or inflammation. The presence of pus and blood suggests that there may be an underlying abscess or fistula.


Diagnosis
To accurately diagnose the condition, a healthcare provider will typically perform:
- Physical Examination: A thorough examination of the anal area to assess the mass.

- Digital Rectal Exam: This may be performed to evaluate the internal structures.

- Imaging Studies: In some cases, an ultrasound or MRI may be necessary to visualize the extent of the problem, especially if a fistula is suspected.


Treatment Options
1. Conservative Management:
- Warm Sitz Baths: Soaking in warm water can help relieve discomfort and promote drainage.

- Pain Relief: Over-the-counter pain relievers like ibuprofen or acetaminophen can help manage pain.

2. Medical Treatment:
- Antibiotics: If there is an infection, antibiotics may be prescribed to help clear it up.

- Drainage: If an abscess is present, it may need to be drained by a healthcare professional. This procedure can provide immediate relief from pain and pressure.

3. Surgical Intervention:
- Fistulotomy: If a fistula is diagnosed, surgical intervention may be necessary to remove the fistula tract.

- Excision: In some cases, the mass may need to be surgically excised, especially if it is recurrent or causing significant symptoms.


When to Seek Medical Attention
It is crucial to seek medical attention if you experience:
- Increased pain or swelling
- Fever or chills, which may indicate a systemic infection
- Persistent bleeding or changes in bowel habits

Conclusion
Given that your external anal mass has been present for over a year and exhibits symptoms such as pain, discharge, and bleeding, it is advisable to consult a healthcare provider for a thorough evaluation. Early diagnosis and appropriate treatment can help alleviate symptoms and prevent complications. Avoid self-treatment without professional guidance, as this could exacerbate the condition. Your health and comfort are paramount, so do not hesitate to seek medical advice.
