Lipschutz Ulcer: A Complete Medical Overview

A Lipschutz ulcer is a painful, sudden-onset genital ulcer that most often affects adolescent girls and young women, frequently after a flu-like or other viral illness. It is not usually caused by sexual activity or a sexually transmitted infection, but medical assessment is important to rule out other causes and provide relief.

What Is a Lipschutz Ulcer?

A Lipschutz ulcer is a sudden, painful ulcer on the vulva, the external genital area. It is also known as non-sexually acquired genital ulceration (NSAGU) or acute genital ulceration. These ulcers are most often reported in adolescents and young women, including people who have never had sexual contact.

The condition can be distressing because the ulcers may look severe and can make sitting, walking, passing urine or wearing close-fitting clothing uncomfortable. However, Lipschutz ulcers are generally not sexually transmitted, are not considered contagious and usually resolve fully with time and supportive care.

A diagnosis should not be made from appearance alone. Several infections, inflammatory conditions and skin disorders can cause genital sores, so a clinician will assess the symptoms carefully and may arrange tests to exclude these alternatives.

Typical Symptoms and Appearance

Lipschutz ulcers often develop rapidly, sometimes over a day or two. They may begin with tenderness, burning, swelling or a small painful area before an open sore becomes visible. One ulcer or several ulcers may occur, commonly on the inner labia, although nearby genital tissue can also be affected.

The ulcers are often deep, well-defined and painful. Their base may appear yellowish, gray or white, with a red or swollen border. Some people develop matching ulcers on opposite sides of the vulva, sometimes described as a “kissing” pattern because the affected surfaces touch each other.

Many people have general symptoms shortly before the ulcers appear. These can include fever, fatigue, sore throat, swollen glands, headache or body aches. Pain with urination is also common, particularly when urine touches the ulcerated skin. These symptoms can overlap with those of other conditions, which is why professional assessment is useful.

Why Do Lipschutz Ulcers Occur?

The precise cause of a Lipschutz ulcer is not fully established. It is thought to result from a strong immune or inflammatory response that affects genital tissue, rather than from direct infection of the ulcer itself. In many cases, symptoms arise after a recent infection elsewhere in the body.

Possible preceding illnesses include infections associated with Epstein-Barr virus, influenza-like illnesses and other viral or bacterial infections. A recent illness may be mild or may have improved by the time genital symptoms start. In some people, no clear trigger is identified.

Lipschutz ulcers are not generally considered a sexually transmitted infection (STI), and their presence does not by itself indicate sexual activity, abuse or poor hygiene. Even so, clinicians should consider each person’s history respectfully and individually, because infections such as genital herpes can also cause painful sores and require different treatment.

Most cases occur only once. Recurring genital or oral ulcers may suggest another condition, such as recurrent aphthous ulceration, Behçet disease, inflammatory bowel disease or a skin disorder, and should be reviewed further.

How Doctors Diagnose the Condition

There is no single test that confirms a Lipschutz ulcer. Diagnosis is based on the pattern of symptoms, a physical examination and exclusion of other causes of genital ulceration. A clinician may ask about recent fever or respiratory illness, previous ulcers, medicines, oral sores, bowel symptoms, eye symptoms and any relevant sexual health history.

Tests often include a swab from the ulcer for herpes simplex virus and, when appropriate, testing for other sexually transmitted infections. Depending on the person’s symptoms and medical history, blood tests may be used to look for recent infection, inflammation or immune-related conditions. Pregnancy testing may also be appropriate for some patients as part of routine safe care.

The examination and testing process should be handled sensitively, especially for adolescents and for anyone who feels anxious about genital symptoms. A person can ask for an explanation before each part of an examination and may discuss whether a support person can be present, in line with local clinical practice.

Further referral to gynecology, dermatology, pediatrics or sexual health services may be recommended if ulcers are recurrent, unusually persistent or accompanied by symptoms affecting other parts of the body.

Treatment and Comfort Measures

Because Lipschutz ulcers usually heal on their own, treatment is mainly aimed at reducing pain and helping the person drink, urinate and rest comfortably. A clinician may recommend suitable pain-relieving medicine, topical anesthetic products or anti-inflammatory treatment based on the individual’s age, symptoms and medical history.

Gentle self-care can also help. This may include rinsing the area with lukewarm water, avoiding fragranced soaps and wipes, wearing loose cotton underwear and choosing soft, non-irritating clothing. A cool compress or shallow lukewarm bath may ease discomfort for some people. It is best to avoid putting unprescribed creams, antiseptics or herbal products directly on the ulcer, as these can irritate sensitive skin.

Passing urine can be particularly painful. Some people find it more comfortable to urinate while rinsing the vulvar area with lukewarm water or while sitting in a shallow bath. Drinking enough fluid is important, as avoiding fluids can lead to dehydration and may make urine more concentrated and uncomfortable.

Severe pain, inability to pass urine or difficulty maintaining fluid intake may require urgent medical support. Rarely, clinicians may use additional treatments, such as short-term anti-inflammatory medication, when symptoms are severe or another inflammatory cause is suspected.

Healing, Outlook and Everyday Care

Lipschutz ulcers commonly improve over days and heal within approximately two to six weeks. Complete healing is expected in most cases, and permanent scarring is uncommon. The timeframe can vary according to the size and depth of the ulcers, the degree of inflammation and whether another health condition is present.

Rest, hydration and pain management can make the recovery period more manageable. Until the area has healed, avoiding friction from cycling, tight clothing and activities that worsen pain may be helpful. Sexual contact should be avoided while ulcers are present, both for comfort and until infectious causes have been appropriately assessed.

Keeping a brief record of symptoms can be useful, particularly if ulcers recur. Notes about fever, sore throat, mouth ulcers, skin rashes, joint pain, eye redness, digestive symptoms or new medicines can help a doctor identify whether further investigation is needed.

For international patients, Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals can assess genital ulcer symptoms and coordinate care when gynecology, dermatology, pediatrics or infectious disease input is needed.

When to Seek Medical Care

Anyone with a new genital ulcer should arrange medical assessment, particularly if the diagnosis is uncertain. Prompt evaluation helps rule out infections such as herpes, identify other possible causes and ensure that pain is managed appropriately. This is important even when there has been no sexual activity.

Urgent medical care is advisable if pain is severe, the person cannot urinate, fluid intake is poor, there are signs of dehydration, fever is persistent or the person feels significantly unwell. Care should also be sought urgently for rapidly spreading redness, pus-like discharge, marked swelling or concern for a serious allergic or medication reaction.

A follow-up appointment is important if ulcers do not begin to improve, last longer than expected, return repeatedly or occur with mouth ulcers, eye pain or redness, bowel symptoms, unexplained weight loss, joint symptoms or widespread skin changes. These features do not necessarily indicate a serious condition, but they warrant a broader medical evaluation.

Frequently asked questions

Is a Lipschutz ulcer an STI?

A Lipschutz ulcer is not usually a sexually transmitted infection and can occur in people who have never had sexual contact. However, genital herpes and other infections can cause similar sores, so testing may be needed before a clinician confirms the diagnosis.

How long does a Lipschutz ulcer last?

Most Lipschutz ulcers heal completely within about two to six weeks. Pain is often most noticeable early in the course, while the ulcer is open. A clinician should review ulcers that persist, worsen or recur.

Can a Lipschutz ulcer come back?

Most people have a single episode and do not experience recurrence. Repeated genital ulcers should be evaluated because recurrent episodes may be linked to another inflammatory, infectious or dermatologic condition.

Can a viral illness trigger a Lipschutz ulcer?

Yes. Many cases occur after a feverish illness, sore throat or other infection, and an immune response may play a role. A preceding infection is not found in every case, and the exact mechanism remains incompletely understood.

What helps with pain when urinating?

A clinician may recommend appropriate pain relief or topical treatment. Some people find that gently rinsing with lukewarm water while urinating reduces stinging, and staying hydrated can help prevent concentrated urine from causing extra discomfort.

Do Lipschutz ulcers leave scars?

Permanent scarring is uncommon because these ulcers usually heal fully. Deep ulcers or significant inflammation can take longer to settle, so follow-up is sensible if healing does not progress as expected.
