What is groin rash?

Rashes are changes in the skin that can involve bumps, color changes, itching, discomfort, and skin sores. Rashes that affect the groin may be limited to the groin or may involve other areas of the body. So-called childhood diseases, such as chickenpox, fifth disease, measles, roseola, and rubella, can cause generalized rashes that may spread to the groin, as can meningococcal meningitis (infection or inflammation of the sac around the brain and spinal cord). Allergic reactions and contact dermatitis are also causes of local or generalized rashes that can involve the groin.

Skin conditions such as eczema, psoriasis, and seborrheic dermatitis can cause red or silver scaly rashes in a variety of areas including the groin. Red or brownish scaly rashes affecting the groin can also occur with infections such as tinea cruris (jock itch) and erythrasma (bacterial infection found in skin folds), or with inflammatory conditions such as intertrigo (inflammation of skin at skin folds). Other inflammatory conditions that can cause groin rashes include Kawasaki disease (condition that causes blood vessel inflammation in children) and erythema nodosum (inflammatory disease causing red nodules on the skin).

Some infections that can be transmitted sexually result in groin rashes, including HIV, syphilis, scabies, Phthirus pubis (pubic lice), and molluscum contagiosum (viral infection). Rashes due to HIV infection and syphilis tend to be reddish or brownish bumps and may involve pustules (pus-filled blisters). Rashes related to scabies and pubic lice tend to form scabs from scratching. The rash associated with molluscum contagiosum consists of small, flesh-colored bumps that often have a central plug of white, waxy material.

Shingles, which is a reactivation of the virus that causes chicken pox, involves a painful blistering rash that generally occurs on one side of the body in a limited area. It can occur in the groin.

There are several compelling reasons to seek prompt medical care if you develop a groin rash, including the possibility of spreading the rash to others or developing significant complications. Prompt medical care is also advisable to ensure that the underlying condition can be evaluated and treated. In some cases groin rashes can be caused by conditions that can have serious or even life-threatening complications. Seek immediate medical care (call 911) if you have a high fever (higher than 101 degrees Fahrenheit) or change in level of consciousness or alertness along with a groin rash.
