Top 10 Butt Bump Causes

  1. 1.Wart

    Warts are non-serious skin growths caused by a virus that infects the top layer of the skin. They are contagious.

    You can try several over-the-counter treatments, including salicylic acid and cryotherapy (freezing). Most warts go away on their own, but less so in adults.

    Rarity:
    Common
    Top Symptoms:
    small butt lump, non-tender butt bump, skin-colored butt bump, scaly butt bump
    Urgency:
    Self-treatment
  2. 2.Skin Abscess

    A skin abscess is an infection of the deeper skin that's typically due to bacteria seen on the skin. Recently, infections are more frequently caused by Staph. Aureus (puts the "staph" in "staph infections").

    You should visit your primary care physician or an urgent care clinic today or tomorrow. Treatment of an abscess includes incision and drainage. It is likely you will be prescribed antibiotics as well. Surgery may be required to get rid of the whole abscess after inflammation has died down. Do not drain the abscess yourself.

    Rarity:
    Common
    Top Symptoms:
    painful butt lump, pink or red butt bump, marble sized butt lump, large butt lump, yellow or white butt bump
    Symptoms that never occur with skin abscess:

  3. 3.Lipoma

    A lipoma is a noncancerous growth of fatty tissue cells. A lipoma can develop in almost any organ of the body although they are most commonly found in the subcutaneous layer just below the skin.

    You do not need treatment for this condition because it is completely benign; however, if the lesion changes at all, a doctor should be consulted. If you would like it removed, a doctor can cut, freeze, or burn it off.

    Rarity:
    Uncommon
    Top Symptoms:
    skin-colored butt bump, small butt lump, marble sized butt lump
    Symptoms that always occur with lipoma:

  4. 4.Skin Cyst

    An epidermoid cyst is a closed sac under the skin filled with a cheese-like or oily material. It is caused by trauma or surgery.

    You do not need treatment for this condition because it is completely benign; however, if the lesion changes at all, a doctor should be consulted. If you would like it removed, a doctor can cut out the cyst.

    Rarity:
    Common
    Top Symptoms:
    skin-colored butt bump, small butt lump, marble sized butt lump

    Acne, also known as pimples, occurs when hair follicles become clogged with oil & dead skin cells. Acne is extremely common and ranges from mild to severe.

    Though some cases of acne prompt patients to visit a dermatologist, most cases can be treated with proper hygiene and over-the-counter medications. Look for products containing benzoyl peroxide or salicylic acid.

  6. 6.Boil (Furuncle)

    Boils are infections of a hair follicle that creates a small pocket of inflammation full of pus. It's typically caused by a common bacteria called S. Aureus.

    Boils typically drain by themselves. You can help by putting a warm compress (be careful not to burn yourself). If things don't get better, go see a doctor who might drain it for you.

  7. 7.Severe Skin Abscess

    A skin abscess is an infection of the deeper skin that's typically due to bacteria seen on the skin. Recently, infections are more frequently caused by Staph. Aureus (puts the "staph" in "staph infections"). If the infection begins to spread, urgent treatment is required.

    You should head to the nearest ER by car since your infection seems like it might be spreading. It is likely that you will be prescribed antibiotics. Surgery may be required to get rid of the whole abscess after the inflammation has died down. Do not drain the abscess yourself.

  8. 8.Atypical Mole

    Moles are growths on the skin. They happen when pigment cells in the skin, called melanocytes, grow in clusters. Certain moles are considered "atypical" because of their size and characteristics, which require careful watching and possibly even biopsy in order to monitor for development into cancer.

    You should go see your primary care doctor to examine the mole. He or she can determine if next steps are necessary.

    Rarity:
    Uncommon
    Top Symptoms:
    atypical features of a butt bump, growing butt bump, small butt lump, marble sized butt lump, butt bump's irregular border

  9. 9.Ringworm (Tinea Corporis)

    Tinea Corporis is a common fungal infection of the skin. This rash is sometimes called "ringworm" and results in ring-shaped redness that is often itchy.

    Ringworm can be treated with topical antifungal ointment such as Lamisil. Apply the ointment directly to the rash and the surrounding skin, and keep the area as dry as possible.

    Rarity:
    Common

  10. 10.Non - Specific Skin Rash

    A rash is an area of irritated or swollen skin. Often, rashes are unidentifiable and some variation of normal. For example, scratching one's arm causes it to turn red (which is caused by mast cells releasing chemicals into the local area), but that's completely normal.

    At this time, you do not need treatment for this rash. If it worsens, you may need to consult a physician.

    Rarity:
    Common
    Top Symptoms:
    rash
    Symptoms that always occur with non-specific skin rash:
