Vulvovaginal Ulcer

What is Vulvovaginal ulcer?

A vulvovaginal ulcer is an open sore or break in the skin or mucous lining of the vulva, vagina, or surrounding genital tissues. The lesion may be painful, bleed easily, and can be accompanied by swelling, discharge, or a burning sensation. Ulcers differ from simple irritation or dermatitis because the tissue loss is deeper, often exposing underlying blood vessels or nerves. While a single ulcer can be caused by an infection, trauma, or an autoimmune condition, multiple or recurrent ulcers may signal a systemic disease.

These lesions are medically significant because they can act as portals for bacteria, potentially leading to secondary infections, and because they sometimes herald underlying conditions that need long‑term management.

Common Causes

There are many reasons why a vulvovaginal ulcer may develop. Below are the most frequently encountered etiologies (listed alphabetically):

• Herpes Simplex Virus (HSV) infection – HSV‑1 or HSV‑2 causes painful vesicles that rupture into shallow ulcers.
• Human Papillomavirus (HPV) – Genital warts with ulceration – High‑risk HPV may cause condyloma that ulcerates after trauma.
• Syphilis (primary stage) – A painless chancre can appear on the vulva.
• Chancroid (Haemophilus ducreyi) – Painful, ragged ulcers with purulent exudate.
• Lichen planus (erosive type) – An autoimmune skin disease that produces erosive plaques and ulcers.
• Lupus erythematosus (systemic or discoid) – May cause chronic ulcerative lesions on the vulva.
• Behçet’s disease – A vasculitic disorder characterized by recurrent genital ulcers.
• Trauma or friction – Rough sexual activity, prolonged cycling, or insertion of foreign objects.
• Chemical or allergic contact dermatitis – Irritants from soaps, spermicides, or latex can lead to erosive lesions.
• Neoplastic conditions – Squamous cell carcinoma or melanoma may present as a non‑healing ulcer.

Other less common causes include tuberculosis of the genital tract, Crohn’s disease (perineal ulceration), and rare infections such as granuloma inguinale (Klebsiella granulomatis).

Associated Symptoms

Vulvovaginal ulcers rarely occur in isolation. Patients often report one or more of the following:

• Burning, stinging, or throbbing pain—especially during urination or intercourse.
• Redness, swelling, or warmth around the lesion.
• Clear, yellow, or bloody discharge.
• Fever, chills, or malaise (suggesting systemic infection).
• Generalized genital itching or a feeling of “rawness.”
• Enlarged or tender inguinal lymph nodes.
• Recurrence of ulcers in the same area or new ulcers elsewhere on the genitalia.
• In chronic autoimmune disease: additional mucosal lesions (e.g., oral ulcers) or skin rashes.

When to See a Doctor

Because vulvovaginal ulcers can be a sign of infection, an autoimmune disease, or malignancy, prompt medical evaluation is important. Seek care if you experience any of the following:

• Ulcer that does not begin to heal within 5‑7 days.
• Severe, worsening pain that interferes with daily activities.
• Fever ≥ 38 °C (100.4 °F) or chills.
• Heavy bleeding or foul‑smelling discharge.
• Swollen, painful groin (inguinal) lymph nodes.
• History of sexually transmitted infections (STIs) or recent unprotected sexual contact.
• Pregnancy—or planning to become pregnant—because certain infections (e.g., HSV) can affect the fetus.
• Any suspicion of cancer (hard, irregular lesion, or ulcer that continues to grow).

Diagnosis

Evaluation begins with a thorough history and physical examination, followed by targeted tests.

1. Clinical History

• Onset, duration, and progression of the ulcer.
• Recent sexual activity, travel, or exposure to new soaps, detergents, or contraceptives.
• Past episodes of similar lesions or known chronic diseases (e.g., lupus, Behçet’s).
• Medication list—including over‑the‑counter products.

2. Physical Examination

• Visual inspection of the vulva and vagina (often with a speculum).
• Palpation of surrounding tissue and inguinal lymph nodes.
• Assessment for other mucosal lesions (oral cavity, anus).

3. Laboratory & Imaging Tests

• Swab for PCR or culture – Detects HSV, HSV‑2, HPV, HSV‑1, Chlamydia, Gonorrhea, Treponema pallidum (syphilis), and Haemophilus ducreyi.
• Serologic testing – RPR/VDRL for syphilis; HIV screening; ANA, dsDNA for lupus; HLA‑B51 for Behçet’s (supportive).
• Biopsy – Indicated for ulcers >2 weeks, atypical appearance, or suspicion of malignancy. Pathology can differentiate cancer, lichen planus, or granulomatous disease.
• Blood counts & inflammatory markers – CBC, ESR, CRP can reveal systemic infection or inflammation.
• Urinalysis – Rules out concurrent urinary tract infection that may irritate the ulcer.

4. Referral

If an autoimmune or oncologic cause is suspected, referral to a dermatologist, rheumatologist, or gynecologic oncologist is recommended.

Treatment Options

Treatment is guided by the underlying cause and the severity of symptoms. A combination of medical therapy, self‑care measures, and follow‑up is usually most effective.

1. Antiviral Therapy

• HSV infection: Acyclovir 400 mg orally three times daily, valacyclovir 1 g twice daily, or famciclovir 500 mg twice daily for 7‑10 days. Suppressive therapy (daily low‑dose antiviral) is advised for recurrent outbreaks.

2. Antibiotic Therapy

• Syphilis: Benzathine penicillin G 2.4 million units IM single dose (earlier stage) or weekly for 3 weeks (late stage).
• Chancroid: Azithromycin 1 g orally single dose or ceftriaxone 250 mg IM plus doxycycline 100 mg twice daily for 7 days.
• Secondary bacterial infection: Trimethoprim‑sulfamethoxazole, clindamycin, or metronidazole based on culture results.

3. Anti‑inflammatory / Immunomodulatory Therapy

• Lichen planus or erosive vulvovaginitis: High‑potency topical corticosteroids (clobetasol 0.05% ointment) applied twice daily for 2‑4 weeks, then tapered.
• Lupus or Behçet’s disease: Systemic agents such as hydroxychloroquine, colchicine, or low‑dose prednisone; biologics (e.g., infliximab) for refractory cases.

4. Pain Management

• Topical lidocaine 2–5% gel or lidocaine‑prilocaine 2.5%/2.5% cream applied before intercourse.
• Oral NSAIDs (ibuprofen 400‑600 mg q6‑8h) for mild‑moderate pain.
• Acetaminophen or short courses of opioid analgesics for severe pain (under physician supervision).

5. Wound Care & Home Measures

• Gentle cleansing with warm water; avoid scented soaps, douches, or antiseptic wipes.
• Pat dry with a soft towel; consider a barrier ointment (e.g., zinc oxide) to reduce friction.
• Wear loose‑fitting, breathable cotton underwear and avoid tight jeans.
• Apply a warm sitz bath (15‑20 minutes, 2–3 times daily) to promote circulation and comfort.
• Refrain from sexual activity until the ulcer heals or until a healthcare provider clears you.

6. Follow‑up

Re‑evaluate within 1–2 weeks after initiating therapy. Persistent or enlarging lesions warrant repeat examination, possible biopsy, or referral to a specialist.

Prevention Tips

Many vulvovaginal ulcers are preventable through lifestyle modifications and safe practices.

• Practice safe sex: Use condoms consistently and discuss STI testing with partners.
• Vaccinate: HPV vaccination (recommended up to age 45) reduces HPV‑related lesions.
• Avoid irritants: Choose fragrance‑free, hypoallergenic soaps, laundry detergents, and laundry softeners.
• Lubricate: Use water‑based lubricants during sexual activity to minimize friction.
• Manage chronic diseases: Keep lupus, Behçet’s, and inflammatory bowel disease well‑controlled with regular follow‑up.
• Prompt treatment of STIs: Early antibiotic or antiviral therapy lessens ulcer formation.
• Good genital hygiene: Wash external genitalia with warm water; avoid douching.
• Regular pelvic exams: Early detection of precancerous changes or atypical lesions reduces risk of malignant ulcers.
