What is plasma cell vulvitis (Zoon's vulvitis)?

Plasma cell vulvitis, also called Zoon's vulvitis, is a rare, chronic inflammatory condition of the vulvar mucosa characterized by persistent, bright red, shiny mucosal plaques. It is a benign condition but must be distinguished from other more serious diagnoses including erosive lichen planus, lichen sclerosus, and early vulvar cancer - all of which can look similar. Biopsy is typically required for accurate diagnosis. Treatment includes topical corticosteroids or calcineurin inhibitors, and resistant cases may require laser ablation, cryotherapy, or surgery.

What are aphthous ulcers of the vulva, and how are they different from herpes?

Aphthous vulvar ulcers (also called Lipschutz ulcers) are deep, painful, well-defined genital ulcers with a yellow-gray base that appear suddenly and are not sexually transmitted. They are most common in young women and are typically triggered by a systemic infection (Epstein-Barr virus, CMV, mycoplasma, Lyme disease) or intense stress. Unlike herpes, they have no prior history of sexual contact required and are negative for HSV on testing. They are painful but self-limiting.

What is Behcet's disease?

Behcet's disease is a rare, chronic systemic inflammatory disorder that causes recurrent oral and genital ulcers, along with eye inflammation and skin lesions. It is distinguished from simple aphthous vulvar ulcers by its recurrent pattern, oral ulcer involvement, and potential for eye and skin manifestations. It is diagnosed clinically based on the pattern of recurrence and multi-system involvement. Treatment includes corticosteroids and systemic anti-inflammatory medications.

What is pruritis vulvae?

Pruritis vulvae refers to chronic vulvar itching as a symptom - not a diagnosis. It is extremely common and can result from many underlying causes including lichen sclerosus, lichen simplex chronicus, contact dermatitis, vulvar atrophy, recurrent infections, psoriasis, or other skin conditions. Effective treatment requires identifying the specific underlying cause rather than treating the itch symptom in isolation.

What is vulvar granuloma fissuratum?

Vulvar granuloma fissuratum involves recurrent tearing or splitting of the vulvar skin - most commonly at the posterior fourchette or around the clitoral hood. It is typically caused by underlying skin conditions (lichen sclerosus), vaginal atrophy, pelvic floor hypertonicity stretching fragile tissue, or poorly healed obstetric injuries. The fissures cause pain during intercourse and can bleed. Treatment addresses the underlying cause and may include topical corticosteroids, hormone therapy, dilators, and in persistent cases, minor surgical repair.

Vulvar Skin Conditions

Gentle, Expert Care for Vulvar Skin Conditions

When vulvar itching, irritation, or pain doesn't go away, the right diagnosis matters.

Vulvar itching, burning, irritation, pain, or changes in the skin can have many different causes. Sometimes the cause is straightforward, such as contact irritation. In other cases, conditions such as lichen sclerosus, lichen planus, chronic yeast infections, or other inflammatory skin disorders may look similar but require different treatment. This is why persistent vulvar symptoms should not simply be treated as an infection or irritation without determining what is causing them.

Dr. Karen Toubi takes a careful approach to vulvar health, starting with your symptoms, medical history, and a thorough examination. When needed, targeted testing or a biopsy can help clarify the diagnosis and guide treatment.

The goal is simple: understand what's causing your symptoms and treat the underlying condition.

Common Vulvar Skin Conditions

Chronic vulvar itching, also called pruritus vulvae, can have many possible causes.

These may include:

Lichen sclerosus

Lichen simplex chronicus

Contact dermatitis

Vaginal or vulvar atrophy

Recurrent candidiasis

Psoriasis

Other inflammatory skin conditions

Treating the itching alone may provide temporary relief without addressing the underlying cause.

If itching continues despite treatment, a more detailed evaluation may be needed. Depending on the findings, this can include examination of the vulvar skin, targeted testing, or biopsy.

Rare Vulvar Conditions Need Careful Evaluation

Some vulvar disorders are uncommon and can resemble more familiar conditions.

Rare inflammatory

Plasma Cell Vulvitis (Zoon's Vulvitis)

Plasma cell vulvitis, also called Zoon's vulvitis, is a rare chronic inflammatory condition that may appear as persistent red or reddish-orange, shiny patches on vulvar tissue.

Because its appearance can overlap with other inflammatory conditions, diagnosis may require a biopsy.

Treatment: depends on the individual diagnosis and may include topical corticosteroids or other prescribed therapies.

Acute ulcers

Aphthous Vulvar Ulcers (Lipschutz Ulcers)

Aphthous vulvar ulcers are painful ulcers that can appear suddenly. They are not considered sexually transmitted infections and may occur in association with certain systemic illnesses or infections.

Treatment: generally focuses on symptom relief and addressing any underlying trigger when one is identified.

Recurrent / Systemic

Behcet's Disease

Behçet's disease is a systemic inflammatory condition that can cause recurrent genital ulcers along with other symptoms, including recurrent oral ulcers and eye inflammation.

Treatment: Because it affects more than the vulvar area, evaluation may involve coordination with other medical specialists. .

Structural / Skin

Vulvar Granuloma Fissuratum

Vulvar fissures can cause sharp pain, tearing, and sometimes bleeding, particularly during intercourse. Possible contributing factors include fragile vulvar tissue, hormonal changes, inflammatory skin conditions, pelvic floor muscle tension, or previous injury.

Treatment: focuses on identifying and addressing the underlying cause. In persistent cases, additional procedures may be considered.

For all biopsies and office procedures: Dr. Toubi offers nerve blocks and nitrous oxide (laughing gas) as standard pain management - not an afterthought.

How Vulvar Skin Conditions Are Evaluated

Getting the right vulvar skin condition treatment starts with identifying the condition causing your symptoms.

Your evaluation may include:

Detailed Symptom History

Dr. Toubi will discuss when your symptoms started, what makes them better or worse, previous treatments, and how the symptoms affect your daily life and sexual health.

Vulvar Examination

A careful examination can help identify patterns of inflammation, skin changes, fissures, lesions, or other findings that may point toward a specific diagnosis.

Targeted Testing

When an infection or another condition is suspected, appropriate testing can help distinguish between possible causes.

Biopsy When Indicated

A small tissue sample may be recommended when the diagnosis is uncertain or when a particular skin condition needs to be confirmed.

A biopsy does not automatically mean cancer is suspected. It is a diagnostic tool that can help distinguish between conditions that may look similar.

Vulvar Irritation Treatment Depends on the Cause

There is no single treatment for vulvar irritation because irritation can have many different causes.

Depending on the diagnosis, treatment may involve:

Prescription topical corticosteroids

Frequently asked questions

What are common vulvar skin conditions ?

Common vulvar conditions include contact dermatitis, lichen sclerosus, lichen planus, lichen simplex chronicus, psoriasis, recurrent yeast infections, and other inflammatory or infectious conditions.

Because several conditions can cause similar symptoms, an examination may be needed to determine the cause.

What causes persistent vulvar itching?

Persistent vulvar itching can result from skin conditions such as lichen sclerosus, lichen simplex chronicus, dermatitis, psoriasis, or vulvar atrophy. Infections such as candidiasis can also cause itching.

If itching continues after treatment, it is worth having the diagnosis reassessed rather than repeatedly treating the symptom.

When should I see a doctor about vulvar irritation?

Consider an evaluation if vulvar irritation is persistent, keeps returning, interferes with daily activities or intimacy, or does not improve after removing a suspected irritant or completing treatment.

New changes in vulvar skin, persistent sores, ulcers, bleeding, thickening, or changes that do not heal should also be evaluated.

Does a vulvar skin condition require a biopsy?

Not always. Many vulvar conditions can be diagnosed through medical history and examination. A biopsy may be recommended when the appearance is unusual, the diagnosis is uncertain, symptoms do not respond as expected, or a tissue diagnosis is needed to distinguish between different condition.
