Ulcus Vulvae (Vulvar Ulcer) – A Complete Patient Guide

Overview

Ulcus vulvae, commonly called a vulvar ulcer, is an open sore or lesion that develops on the external female genitalia (the vulva). Unlike a small abrasion, an ulcer penetrates the surface epithelium and may involve underlying tissue, often causing pain, bleeding, and a burning sensation.

Vulvar ulcers can affect women of any age, but certain forms are more common in specific groups:

  • Adolescents and young adults (15–30 y) – frequently linked to sexually transmitted infections (STIs) such as herpes simplex virus (HSV) or syphilis.
  • Post‑menopausal women – may arise from chronic dermatoses (e.g., lichen sclerosus) or malignancy.
  • Pregnant women – a rare condition called “puerperal vulvar ulcer” can appear in the third trimester.

Exact prevalence is difficult to determine because vulvar ulcers are often under‑reported; however, epidemiologic studies suggest that up to 10 % of women presenting with genital complaints have an ulcerative lesion, with HSV‑2 accounting for roughly 40‑60 % of cases in sexually active adults[1].

Symptoms

Symptoms vary according to the underlying cause, size of the ulcer, and the patient’s immune status. Common manifestations include:

  • Pain or burning sensation – often sharp, worsening during intercourse, tampon use, or urination.
  • Visible ulcer(s) – may be solitary or multiple; shape can be round, oval or irregular, with a raised or undermined edge.
  • Redness and swelling (erythema) of the surrounding vulvar skin.
  • Discharge or exudate – serous, purulent, or bloody, depending on infection or trauma.
  • Itching (pruritus) – especially in ulcerative dermatoses.
  • Fever, chills, or malaise – more typical of systemic infections (e.g., syphilis, chancroid).
  • Difficulty walking or sitting – due to pain.
  • Dyspareunia (painful intercourse) – a frequent complaint.
  • Bleeding – may be spontaneous or triggered by friction.
  • Swollen lymph nodes in the groin – suggests an infectious etiology.

If an ulcer is present for more than 3 weeks without healing, or if there are atypical features (e.g., hard indurated base, ulcer on the labia majora in a post‑menopausal woman), malignancy must be considered.

Causes and Risk Factors

Vulvar ulcers are a symptom, not a disease itself. They can arise from infectious, inflammatory, traumatic, or neoplastic processes.

Infectious Causes

  • Herpes Simplex Virus (HSV‑1 or HSV‑2) – the most common cause; lesions appear 2–12 days after exposure and heal within 2–3 weeks.
  • Syphilis (primary chancre) – painless ulcer, usually solitary, appears 3 weeks after exposure.
  • Chancroid (Haemophilus ducreyi) – painful, ragged ulcer with purulent exudate, more common in regions with high STI rates.
  • Granuloma inguinale (Klebsiella granulomatis) – beefy-red ulcer without pain, rare in the U.S.
  • Human papillomavirus (HPV)–related warts – can undergo ulceration after trauma.
  • Fungal or bacterial superinfection of a pre‑existing lesion.

Inflammatory / Autoimmune Disorders

  • Lichen sclerosus – a chronic dermatosis that can ulcerate, especially in post‑menopausal women.
  • Lichen planus – erosive variant may cause painful ulcers.
  • Behçet’s disease – systemic vasculitis presenting with recurrent genital ulcers.
  • Autoimmune blistering diseases (e.g., pemphigus vulgaris, bullous pemphigoid) – may result in ulceration after blister rupture.

Traumatic / Mechanical Causes

  • Sexual activity, friction from tight clothing, or use of harsh soaps.
  • Procedural trauma (e.g., biopsies, episiotomy, catheter insertion).
  • Self‑inflicted injuries or sexual assault.

Neoplastic Causes

  • Squamous cell carcinoma of the vulva – may begin as a non‑healing ulcer.
  • Paget disease of the vulva – eczema‑like lesions that can ulcerate.

Risk Factors

  • Multiple sexual partners or inconsistent condom use.
  • History of other STIs.
  • Immunosuppression (HIV, organ transplant, systemic steroids).
  • Smoking – linked to both HPV‑related disease and vulvar cancer.
  • Chronic irritation (diapers, wet clothing, chemical irritants).
  • Age > 60 y (higher risk of malignancy).

Diagnosis

Accurate diagnosis requires a combination of history, physical examination, and targeted investigations.

Clinical Evaluation

  1. Detailed sexual and medical history – onset, number of lesions, prior STIs, contraceptive use, systemic symptoms.
  2. Visual inspection – note size, number, shape, base (clean, indurated, necrotic), and presence of vesicles or crust.
  3. Pain assessment – using a numeric rating scale (0‑10).

Laboratory Tests

  • Polymerase Chain Reaction (PCR) or viral culture for HSV – most sensitive.
  • Serologic testing for syphilis (RPR/VDRL and confirmatory treponemal test).
  • Gram stain and bacterial culture if purulent discharge suggests chancroid or secondary bacterial infection.
  • HSV serology (IgG/IgM) when PCR unavailable.
  • HIV test – recommended for all patients with genital ulcers.

Biopsy

Indicated when:

  • Ulcer persists > 4 weeks despite appropriate therapy.
  • Lesion has suspicious features (indurated border, raised edges, nodularity).
  • Patient is > 50 y or has risk factors for vulvar cancer.

Histopathology can differentiate infectious, inflammatory, and neoplastic causes.

Additional Imaging (rare)

  • Pelvic MRI or ultrasound – if deep tissue involvement or suspicion of malignancy.

Treatment Options

Treatment is directed at the underlying cause, symptom relief, and prevention of complications.

1. Antiviral Therapy (viral infections)

  • Acyclovir 400 mg PO three times daily for 7‑10 days (first‑line for HSV).
  • Valacyclovir 1 g PO twice daily or 500 mg three times daily.
  • For immunocompromised patients, longer courses (14‑21 days) may be needed.

2. Antibiotic Therapy (bacterial infections)

  • Syphilis – Benzathine penicillin G 2.4 MU IM single dose (early syphilis); follow‑up serology at 3, 6, and 12 months.
  • Chancroid – Azithromycin 1 g PO single dose *or* Ceftriaxone 250 mg IM single dose.
  • Granuloma inguinale – Doxycycline 100 mg PO twice daily for 3 weeks.

3. Topical Treatments

  • Topical antiviral creams (e.g., penciclovir) – adjunctive for HSV; not a substitute for systemic therapy.
  • High‑potency corticosteroid ointment (clobetasol 0.05 %) – used for inflammatory ulcers (lichen sclerosus, Behçet’s) after diagnosis.
  • Antiseptic washes – diluted sodium hypochlorite (Dakin’s solution) or chlorhexidine to reduce bacterial load.

4. Pain and Symptom Management

  • Analgesics – acetaminophen or NSAIDs (ibuprofen 400‑600 mg q6‑8h) unless contraindicated.
  • Topical lidocaine 5 % gel for brief relief before urination or intercourse.
  • Heat or cold packs as tolerated.

5. Surgical / Procedural Options

  • Debridement of necrotic tissue in severe ulcerations.
  • Electrosurgical excision or laser ablation for refractory lichen sclerosus or small vulvar cancers.
  • In cases of malignancy – wide local excision, radical vulvectomy, or Mohs micrographic surgery per oncologic guidelines.

6. Lifestyle and Supportive Care

  • Stop smoking – improves healing and reduces cancer risk.
  • Wear breathable cotton underwear, avoid tight clothing.
  • Practice good genital hygiene—mild, fragrance‑free cleansers, pat dry.
  • Use water‑based lubricants during sexual activity.
  • Consider counseling for sexual trauma or anxiety related to recurrent ulcers.

Living with Ulcus Vulvae (Vulvar Ulcer)

Managing a vulvar ulcer goes beyond medical treatment. Below are practical tips for daily life.

Hygiene

  • Clean the area gently with lukewarm water; avoid scrubbing.
  • After bathing, pat the vulva dry; do not let moisture linger.
  • Change menstrual products (tampons/pads) every 4‑6 hours.

Clothing Choices

  • Opt for loose, breathable cotton underwear.
  • Avoid synthetic fabrics, tight leggings, or denim that can trap sweat.

Sexual Activity

  • Delay intercourse until the ulcer has fully healed.
  • When resuming, use a generous amount of water‑based lubricant to reduce friction.
  • Communicate openly with your partner; consider using condoms to prevent STI transmission.

Pain Management

  • Take scheduled OTC pain relievers rather than waiting for breakthrough pain.
  • Warm sitz baths (10‑15 min, 2–3 times daily) can soothe discomfort.
  • Apply a thin layer of a barrier cream (e.g., zinc oxide) after bathing to protect skin.

Follow‑up Care

  • Attend all scheduled appointments; most ulcerative conditions require monitoring for recurrence.
  • Maintain a symptom diary – note ulcer size, pain score, triggers, and medication adherence.
  • Notify your clinician promptly if the ulcer enlarges, becomes increasingly painful, or fails to improve after 2 weeks of appropriate therapy.

Prevention

While not all vulvar ulcers are preventable, many risk factors are modifiable.

  • Safe sexual practices – consistent condom use, limiting the number of partners, and regular STI screening.
  • Vaccination – HPV vaccine (recommended up to age 45) reduces risk of HPV‑related lesions that may ulcerate.
  • Smoking cessation – cuts risk of lichen sclerosus progression and vulvar cancer.
  • Skin care – avoid irritants (perfumed soaps, douches), use hypoallergenic lubricants.
  • Prompt treatment of infections – early therapy for STIs prevents ulcer formation.
  • Regular gynecologic exams – especially after menopause, to detect premalignant changes early.

Complications

If left untreated or inadequately managed, vulvar ulcers can lead to serious outcomes:

  • Secondary bacterial infection – cellulitis, abscess formation, or sepsis.
  • Chronic pain syndromes – persistent neuropathic pain may develop.
  • Dyspareunia and sexual dysfunction – leading to relationship strain.
  • Scarring and adhesions – can cause anatomical distortion and urinary obstruction.
  • Progression to malignancy – especially in persistent ulcerations associated with lichen sclerosus or HPV‑related dysplasia.

When to Seek Emergency Care

Call emergency services (911) or go to the nearest emergency department if you experience any of the following:

  • Severe, uncontrolled bleeding that does not stop after applying pressure for 10 minutes.
  • Rapidly spreading infection with fever > 38.5 °C (101.3 °F), chills, or feeling faint.
  • Sudden, intense pain that prevents you from sitting or walking.
  • Signs of a severe allergic reaction after medication (hives, swelling of the face or throat, difficulty breathing).
  • Visible foul‑smelling pus with swelling suggesting a deep abscess.

Prompt emergency evaluation can prevent life‑threatening complications.
