  1. 1.Non - Specific Skin Rash

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.
