Top 9 Scrotal Rash Causes

  1. 1.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:
    rash
    Urgency:
    Wait and watch
  2. 2.Non - Specific Dermatitis (Skin Inflammation)

    Dermatitis is the inflammation ("-itis") of the skin ("derma" is a layer of the skin). It can be caused by any number of causes, from allergies to infections to autoimmune issues. Dermatitis of Normal Variation (also called, "NOS") means that all of those other causes of your rash have been ruled out. This is very common.

    You can treat this at home and the rash should go away on its own. In the meantime, you can use an anti-histamine (both by mouth OR as an ointment), or a topical corticosteroid to treat the itch and/or pain due to the rash.

    Rarity:
    Common
    Top Symptoms:
    red rash, itchy rash, painful rash
    Symptoms that always occur with non-specific dermatitis (skin inflammation):
    red rash
    Urgency:
    Self-treatment
  3. 3.Irritant Contact Dermatitis

    Contact dermatitis is a condition in which the skin becomes red, sore, or inflamed after direct contact with a substance. This condition most often affects skin of the hands, and may occur after repeated and prolonged exposure to substances such as water, detergents (soaps, bleach), solvents (such as gasoline), acids, powders, dust, and soil. The onset of the skin reaction is usually within 48 hours of coming in contact with the substance.

    You can safely treat this condition on your own. The main treatment for this disease is to avoid the substance that triggers the skin inflammation. Moisturizer can also be helpful to provide relief for your inflamed skin.

    Rarity:
    Common
    Top Symptoms:
    rash with well-defined border, itchy rash, red or pink, rough patch of skin, painful rash, red rash
    Symptoms that always occur with irritant contact dermatitis:
    rash with well-defined border
    Symptoms that never occur with irritant contact dermatitis:
    fever, black-colored skin changes, brown-colored skin changes, blue-colored skin changes
    Urgency:
    Self-treatment
  4. 4.Eczema (Atopic Dermatitis)

    Eczema is a form of skin inflammation that causes skin to be dry, itchy, red, and irritated.

    You should go to your local pharmacy or retail clinic to be treated. The usual treatment for atopic eczema involves avoiding irritants and other triggers, using moisturizers to prevent inflammation, as well as steroid creams and ointments when the inflammation flares up.

    Rarity:
    Common
    Top Symptoms:
    trouble sleeping, feeling itchy or tingling all over, dry skin, scalp itchiness, flexor surface rash
    Symptoms that never occur with eczema (atopic dermatitis):
    fever
    Urgency:
    Phone call or in-person visit

  5. 5.Psoriasis

    Psoriasis is a skin disease that causes itchy or sore patches of thick, red skin with silvery scales. The patches mostly affect the elbows, knees, scalp, back, face, palms and feet.

    There are many over-the-counter creams that could help which you can first try to see if your symptoms get better. However, psoriasis is a diagnosis that should be made by a physician and might need longer term follow up.

    Rarity:
    Uncommon
    Top Symptoms:
    itchy rash, red or pink, rough patch of skin, rash with well-defined border, painful rash, scaly rash
    Symptoms that never occur with psoriasis:
    fever, black-colored skin changes, brown-colored skin changes, blue-colored skin changes
    Urgency:
    Primary care doctor
  6. 6.Molluscum Contagiosum

    Molluscum Contagiosum is a common viral infection of the skin that usually affects young children, sexually active young adults, and patients with a weakened immune system.

    You can go to a primary care doctor, who might recommend cryotherapy (freezing it off) or ointments. That being said, molluscum contagiosum often goes away on its own.

    Rarity:
    Common
    Top Symptoms:
    rash with bumps or blisters, skin changes on arm, leg skin changes, head or neck skin changes, genital skin changes
    Symptoms that never occur with molluscum contagiosum:
    fever, headache
    Urgency:
    Phone call or in-person visit
  7. 7.Sunburn

    A sunburn is inflammation (a reaction by your body's immune system) caused by too much UV (ultra-violet) radiation, which is part of the sunshine. While the symptoms eventually go away, the cells of the skin are permanently damaged, and over time, the risk of skin cancer is higher. Further, the damage reduces the skin's ability to repair itself, speeding up the formation of wrinkles and other signs of aging.

    Although there is not much clinical evidence to support its effectiveness, moisturizers like aloe vera and oil-based lotions, creams, and ointments provide a protective layer on the damaged skin, speeding up healing. Cool compresses are also useful. Ibuprofen or other similar NSAIDs are effective in reducing inflammation and pain. Wearing sunscreen when going back out in the sun is also key to reducing further damage.

    Rarity:
    Common
    Top Symptoms:
    painful rash, red rash, itchy rash, warm and red rash, swollen rash
    Symptoms that always occur with sunburn:
    painful rash, red rash
    Symptoms that never occur with sunburn:
    fever
    Urgency:
    Self-treatment
  8. 8.Insect Bite From a Chigger

    Chiggers are mites that feed on humans and animals only while they are larvae, or their infant form. People can contract chiggers when they contact infected grass. Chiggers feed for three to four days on a piece of skin, and secrete a fluid that causes intense itching.

    You should go to a retail clinic to be treated, as household remedies aimed at killing the mite are unlikely to be effective. The infected area should be kept clean with soap and water. A hydrocortisone cream or local anesthetic may be helpful to reduce the itching. You should avoid scratching the wounds!

    Rarity:
    Rare
    Top Symptoms:
    lower leg itch, constant skin changes, itchy rash, knee itch, lower leg redness
    Urgency:
    Phone call or in-person visit
  9. 9.Amyloidosis

    Amyloidosis is a condition where a protein, called amyloid, deposits in the body's tissues and organs (commonly the heart and kidneys). This can lead to dysfunction and damage in these tissues and organs.

    You should visit your primary care physician in the next few days. Blood, tissue, and imaging tests can be completed to confirm the diagnosis. If confirmed, a treatment plan can be made to manage the effects of the disease. Results vary with treatment and are dependent on the extent of the deposits.

    Rarity:
    Rare
    Top Symptoms:
    fatigue, shortness of breath, diarrhea, unintentional weight loss, dizziness
    Urgency:
    Primary care doctor

FAQs About Scrotal Rash

Here are some frequently asked questions about scrotal rash.

Why won't my scrotal rash go away?

You can get a scrotal rash for several reasons and that may not be going away. One major cause of scrotal rashes are infections such as scabies, pubic lice, or fungi. Other sexually transmitted infections (STIs) can also present as a rash. If the rash is not infectious in nature, it is most likely due to inflammation of the skin due to conditions like dermatitis, eczema, or heat rash.

Why does my toddler have a scrotal rash?

Scrotal rashes in children are usually caused by some sort of irritant. Common irritants include an allergic reaction to new laundry detergent or soaps as well as stool and urine left in prolonged contact with the skin in those wearing diapers. More rarely, children can also have rash secondary to infections such as candidiasis, staph scalded skin syndrome, or other bacteria. In the case of bacterial infection, it is important that children get immediately treated before the rash progresses to a more serious condition such as cellulitis.

Do yeast infections cause scrotal rashes?

Yes, yeast infections can cause scrotal rashes, most commonly in infants between three to four months of age. Infections also often occur in elderly adults with incontinence. It is one of the major causes of rashes on the scrotum as the moist and warm area near the genitals creates an environment favorable for yeast growth. Yeast infections will be red, itchy, and slightly raised with pustules surrounding the edges of the lesion.

Why is my scrotal rash not itchy?

A non-itchy scrotal rash increases the likelihood of having miliaria (not to be confused with the mosquito-borne illness malaria), also known as heat rash or sweat rash, that is a transient disorder caused by blockage within the sweat duct. Hot and humid environments, strenuous physical activity, and tight clothing that occludes the skin are all risk factors for developing this particular type of rash.

Why do I get a scrotal rash after shaving?

Shaving hair on the scrotum, especially if done improperly, increases the risk of ingrown hairs as hair tends to grow downward or curl into the skin. This can lead to pseudofolliculitis, which is especially prevalent in black men due to the curly nature of their hair. Poor shaving hygiene can also introduce bacteria to the hair follicles and can cause inflammation of the follicles called folliculitis. Bacterial folliculitis will present as red papules and pustules whereas pseudofolliculitis will present as firm, skin-colored, sometimes hyperpigmented papules.
