Anal issues


Hello doctor, I would like to ask: Recently, while bathing, I noticed a soft lump under the skin on the right side of the anal area.
It doesn't hurt, but there is slight tenderness when pressed.
The color is similar to my skin tone but slightly whitish.
I have never felt this before.
Could this be folliculitis? However, there is no pus or redness.

Hello: Based solely on the textual description, it is not possible to accurately diagnose a skin condition.
If the skin condition does not improve or worsens, it is advisable to consult a dermatologist to confirm whether it is another skin disorder.
Thank you!

More Info


When it comes to soft bumps near the anus, there are several potential causes that could explain your symptoms. Based on your description, it sounds like you may be experiencing a benign condition, but it’s important to consider various possibilities.

1. Sebaceous Cysts: These are common and often harmless lumps that can occur anywhere on the body, including near the anus. They are usually filled with a substance called sebum, which is produced by sebaceous glands. Sebaceous cysts are typically soft, movable, and can be skin-colored or slightly white. They are generally painless unless they become infected.

2. Hemorrhoids: While you mentioned that the bump is soft and not painful, it’s worth noting that hemorrhoids can sometimes present as soft lumps near the anus. They can be internal or external, and while external hemorrhoids can be painful, internal ones may not cause discomfort unless they become thrombosed (clotted). Hemorrhoids can also appear as skin-colored lumps.

3. Skin Tags: These are small, soft, benign growths that can occur around the anal area. They are usually painless and can be skin-colored or slightly darker. Skin tags are often a result of friction or irritation and are not typically a cause for concern.

4. Folliculitis: While you mentioned the possibility of folliculitis (inflammation of hair follicles), it usually presents with redness, swelling, and sometimes pus. Since you noted that there is no redness or pus, it is less likely to be folliculitis. However, mild cases can sometimes present without these classic signs.

5. Anal Warts: Caused by the human papillomavirus (HPV), anal warts can appear as soft, flesh-colored bumps. They may not be painful but can vary in size and number. If you have had any risk factors for HPV, such as unprotected sexual contact, this could be a consideration.

6. Other Conditions: There are other less common conditions that could cause soft bumps near the anus, including infections or other dermatological issues. If the bump changes in size, color, or begins to cause pain, it would be prudent to seek medical evaluation.

Given that the bump is not painful and does not exhibit signs of infection (such as redness or pus), it may not be an urgent issue. However, it is always best to consult with a healthcare professional for an accurate diagnosis. They may perform a physical examination and, if necessary, imaging or a biopsy to rule out any serious conditions.

In summary, while the bump you described could be a sebaceous cyst, skin tag, or possibly a mild case of folliculitis, it is essential to monitor it for any changes. If you notice any new symptoms, such as increased pain, changes in color, or if the bump grows, you should seek medical advice promptly. Regular check-ups and being attentive to changes in your body are key to maintaining good health.
