Small bumps near the anus?


I have a small grayish-black bump about 0.3 centimeters in size next to my anus.
It has been there for two weeks, is not painful, and there is only one.
I would like to know what it could possibly be!

Dr. Ke Fangxu reply Surgery


Perianal masses are often external hemorrhoids, anal fistula openings, or anal fissure polyps.
Without a physical examination, a definitive answer cannot be provided.
However, if there is no pain and no increase in size, it may be advisable to continue monitoring the condition.

More Info


Gray-black bumps near the anus can be concerning, and it's important to understand the potential causes and when to seek medical attention. Given that you have a small gray-black bump approximately 0.3 cm in size that has been present for two weeks without pain, there are several possibilities to consider.

1. Skin Tags: These are benign growths that can appear in various areas of the body, including around the anus. They are typically flesh-colored or slightly darker and can vary in size. Skin tags are usually harmless and do not require treatment unless they become bothersome.

2. Seborrheic Keratosis: This is a common, non-cancerous skin growth that can appear as a gray, black, or brown bump. They often have a waxy or scaly appearance and are generally harmless.

3. Hemorrhoids: While typically associated with pain and discomfort, hemorrhoids can sometimes present as lumps near the anus. They can be external or internal and may appear darker due to blood pooling.

4. Pigmented Lesions: These can include moles or other pigmented skin lesions that may develop in the anal area. While many are benign, any new or changing pigmented lesion should be evaluated by a healthcare professional.

5. Anal Warts: Caused by the human papillomavirus (HPV), anal warts can appear as small bumps and may vary in color. They are usually painless but can be a sign of an underlying infection.

6. Fungal or Bacterial Infections: In some cases, infections can lead to the formation of bumps or lesions around the anus. These may be accompanied by other symptoms such as itching or discharge.

7. Skin Conditions: Conditions like psoriasis or eczema can also cause changes in the skin around the anus, leading to the formation of bumps or patches.

Given that the bump has been present for two weeks without pain, it may not be an immediate cause for concern, especially if there are no other symptoms such as itching, bleeding, or changes in bowel habits. However, it is crucial to monitor the bump for any changes in size, color, or symptoms.


When to Seek Medical Attention
- If the bump changes in size, color, or shape.

- If you experience pain, bleeding, or discomfort.

- If you notice any other unusual symptoms, such as changes in bowel habits or discharge.


Conclusion
While many bumps near the anus can be benign, it is always best to consult with a healthcare professional for an accurate diagnosis and appropriate management. A dermatologist or a gastroenterologist can provide a thorough examination and may recommend further testing if necessary. Early evaluation can help rule out any serious conditions and provide peace of mind.
