Why vulvar dermatology diagnosis matters
The vulva is affected by many of the same skin conditions seen elsewhere on the body—eczema, psoriasis, lichen planus, lichen sclerosus, infections, and both benign and malignant growths—but it also has conditions unique to this anatomical site. Accurate, timely diagnosis matters because:
Quality of life impact: Vulvar skin conditions often cause chronic itching, pain, burning, or discomfort during sex and daily activities, significantly affecting physical comfort, mental health, and intimate relationships.
Cancer risk: Some conditions, notably lichen sclerosus and certain forms of vulvar intraepithelial neoplasia, carry an increased risk of squamous cell carcinoma if left untreated or poorly managed.
Preventing scarring and architectural changes: Conditions like lichen sclerosus and lichen planus can cause permanent scarring, fusion of the labia, or narrowing of the vaginal opening if not treated early.
Fertility and sexual health: Chronic vulvar conditions can affect sexual function and, in some cases, complicate pregnancy or childbirth.
Key challenges in diagnosis
Nonspecific presentation: Many different conditions—infections, inflammatory dermatoses, allergic reactions, and precancerous changes—can all present with similar symptoms (itching, redness, soreness), making clinical differentiation difficult without biopsy.
Modified skin environment: The vulva's moisture, occlusion, and friction alter how skin conditions typically appear compared to their presentation elsewhere on the body, so textbook descriptions don't always translate.
Limited clinician training: Many gynecologists, primary care providers, and even dermatologists receive minimal specific training in vulvar skin conditions, leading to underdiagnosis or misdiagnosis (often mistaken for recurrent yeast infections).
Patient reluctance: Embarrassment or discomfort discussing genital symptoms often delays patients from seeking care, allowing conditions to progress.
Overlapping conditions: Patients frequently have more than one condition simultaneously (e.g., lichen sclerosus plus a secondary yeast or bacterial infection), which can obscure the underlying diagnosis.
Biopsy challenges: While biopsy is often necessary for definitive diagnosis, the area's sensitivity can make patients hesitant, and histological interpretation can still be nuanced.
Lack of standardized terminology: Historically inconsistent naming conventions across specialties (dermatology, gynecology, pathology) have complicated communication and research.
Given these challenges, best outcomes typically come from a multidisciplinary approach—often involving gynecology, dermatology, and sometimes pathology—along with clinician education and patient empowerment to seek care early.
This tutorial is intended for health care practitioners and is not intended to replace clinical judgement or emergent scientific insights into diagnosing and treating dermatologic conditions of the vulva. The following topics listed below are included in this tool, to include pictures, differential, presentation and possible treatment recommendations to consider.

Diagnosis
- Clinical
- Affects the vulva, upper body, breasts and arms (85% on anogenital skin).
- Skin loses pigmentation and becomes smooth.
- Typically hypopigmentation surrounded by hyperpigmentation, but some lesions can appear hyperpigmented in darker skin individuals.
- Characteristic distribution of a figure-of-eight, keyhole, hourglass, or lotus flower when skin shrinks.
- Biopsy
- Can confirm diagnosis if doubtful-->hyperkeratosis, epidermal atrophy, band-like lichenoid infiltrate, upper dermal edema, homogenized sclerotic collagen
Treatment / Management
- Treat with superpotent topical corticosteroids (Clobetasol or halobetasol 0.05% ointment every 12-24 hrs for 1-3 months until skin normalizes) even if asymptomatic and f/u regularly.
- Maintenance therapy (2-3x/wk) is recommended to decrease risk of SCC.
- Can have secondary lichen simplex chronicus or superimposing allergic contact dermaittis.
- Untreated lichen slcerosis can lead to scarring of the vulva, causing erosions, fissures ans shrinking of the introitus (opening of the vagina) and is assoicated with a small increased risk of vulvar cancer (SCC and melanoma).
- Alternative options include:
- A mid potency steroid or tacrolimus ointment for maintenance therapy or mometasone furoate 0.1% ointment
- Intralesional triamcinolone or steroid (potential hypopigmentation or atrophy) injections,
- 308-nm excimer laser, fractional CO2 laser, and platelet-rich plasma, but they do not decrease the risk of SCC.
- Oral therapies are available for resistant cases.
- Should also recommend genital care including on soap or hypoallergenic soap, vaseline during flares and avoiding tight fitting clothing.

Skene Gland Cyst
Description / Key Features
- Results from obstruction of the Skene (paraurethral) ducts and appears as a small, soft or fluctuant mass located lateral to the urethral meatus.
- It may cause dysuria, dyspareunia, postvoid dribbling, or difficulty voiding.
- On pelvic exam, it is often detected as a tender or non-tender suburethral mass.
- While generally benign, infection can lead to abscess formation.
Presentation Timeline
- May be congenital or acquired and can remain asymptomatic for years, gradually enlarging over months to years before being noticed.
- When infection occurs and the cyst becomes an abscess, symptoms such as pain, swelling, and dysuria typically develop over several days to weeks.
Differential Diagnosis
- Urethral diverticulum
- Bartholin gland cyst
- Inclusion cysts
- Benign tumors of the vulva
Diagnosis / Treatment / Management
Diagnosis
- Clinical
- Based on pelvic exam findings of a cystic mass adjacent to the urethral meatus.
- Differentiation from urethral diverticulum is important
- Workup
- MRI or transvaginal ultrasound may be ordered if the diagnosis is unclear.
- Urinalysis may help rule out urinary tract infection or other causes of symptoms.
Treatment / Management
- Removal of the cyst.
- Small cut made in the cyst followed by stitching of the inside edges of the cyst to the surface of the vulva.

Bartholin Gland Cyst
Description / Key Features
- Develops when the duct of the Bartholin gland becomes obstructed, leading to mucus accumulation.
- It presents as a unilateral, soft, fluctuant mass in the posterior introitus.
- Small cysts are often asymptomatic, but larger cysts may cause dyspareunia, discomfort while walking or sitting, or pressure symptoms.
- In some cases, large cysts can distort the vulvar anatomy.
Presentation Timeline
- Develop gradually over weeks to months due to obstruction of the gland’s duct and accumulation of secretions.
- They are often painless and may remain asymptomatic or be discovered incidentally during pelvic examination.
Differential Diagnosis
- Bartholin gland carcinoma folliculitis
- Vulvar inclusion cysts
- Leiomyomas
- Fibromas
Diagnosis / Treatment / Management
Diagnosis
- Clinical
- Based on pelvic exam as a unilateral, fluctuant, non-tender mass in the posterior introitus.
- Workup
- Biopsy is indicated in women over 40 years old or in cases of solid, painless, or recurrent masses to rule out malignancy.
- Imaging is rarely necessary unless malignancy is suspected.
Treatment / Management
- If patient is asymptomatic and under 40: May be treated with a Sitz bath or warm water soaking. Soaks should be done 2x/day for 10 - 15.
- If patient is symptomatic and under 40: Incision and Drainage; Marsupialization, Surgical removal
- If patient is over 40: Surgical removal of entire cyst

- STI testing can be performed if risk factors or patient request are present.
- Biopsy is considered if malignancy is suspected, particularly in women over 40.
Treatment / Management
- Antibiotics.
- Incision into abscess followed by insertion of catheter for drainage.
- If abscess refills after being drained, marsupialization may be done, which creates a permanent opeing for continuous drainage.

Vulvovaginitis
Description / Key Features
- Most simply this is inflammation of the vagina.
- It can cause a array of symptoms that range from itchiness, pain, swelling, and abnormal discharge.
- It's etiology is also numerous.
- It is normally caused by a change of an individual's baseline vaginal bacteria (usually primarily lactobacilli which helps maintain pH) and flora like an irritant or hormonal changes or caused by a infection.
- The change in the vaginal flora can disrupt vaginal pH which causes the array of symptoms.
- Change in color, odor or amount of discharge, vaginal itching or irritation, pain during intercourse
- Burning during urination, and light vaginal bleeding may all be experienced.
- The condition is more common in individuals with a vagina who may be in their reproductive or premenopausal years.
- Bacterial vaginosis, Vaginal Candiasis, Trich, Mycoplasma, and atrophic vaginitis can all cause vaginitis.
Presentation Timeline
- With treatment, acute vaginitis typically resolves within two weeks.
- Chronic or recurrent cases may persist for three to six months.
- Symptom onset can range from a sudden appearance to a gradual progression depending on the underlying cause.
Differential Diagnosis
- Bacterial vaginosis
- Trichomaniasis
- Vaginal Candiasis
- Atropic Vagintis
- Chemical Irrirtant or allergy
- Inflammatory vaginitis
- Foreign body
- STI with cervicitis
- Things that may be mistaken for vaginitis:
- Lichen sclerosis
- Physiologic leukorrhea
- Semen or cervical mucus,
- Contact dermatitis
- Psoarsis or eczema of the vulva
Diagnosis / Treatment / Management
Daignosis
- Clinical diagnosis.
- High clinical suspicion for the underlying cause of the vaginitis should prompt further testing.
- See sections on Bacterial vaginosis, Candidiasis, and Trichomonas for diagnosis.
- Most cases of vaginitis (around 90%) are usually caused by one of these three conditions.
- Wet mount microscopy, gram stain, or cultures may all be required in order to diagnose the underlying cause of the issue
Treatment / Management
- Usually the treatment is focused around treating the underlying cause of the inflammation.
- For Bacterial Vaginosis, the CDC Recommends:
- Metronidazole 500 mg orally twice daily for 7 days
- Metronidazole gel 0.75%, 1 full applicator (5 g) intravaginally, once daily for 5 days
- Clindamycin cream 2%, 1 full applicator (5 g) intravaginally at bedtime for 7 days
- For Bacterial Vaginosis, the CDC Recommends:

Vulvodynia
Description / Key Features
- Complex and chronic vaginal pain condition that involves persistent vulvar pain that cannot be traced to an identifiable cause.
- There is a subtype of vulvodynia called clitorodynia which only affects the clitoris.
- The pain often is described as a burning pain that can be exacerbated by specific activities like exercise, sex, or prolonged standing.
- It can also be exacerbated by tight fitting clothing, anxiety, depression, or stress.
- The pain can also radiate from the vulva and involve the labia or even the thighs.
- The pain can be generalized but it can also be localized.
- A key pertinent negative with this conditions is that there are usually no skin findings.
Presentation Timeline
- The onset of vulvodynia varies widely, with symptoms developing suddenly or gradually and lasting for months to years.
- Some cases resolve spontaneously, while others become chronic with unpredictable duration.
Differential Diagnosis
- Infectious causes: Vulvovaginal candidiasis (including atypical forms), bacterial vaginosis, trichomoniasis, or genital herpes
- Inflammatory conditions: Lichen sclerosus, lichen planus, contact dermatitis, and lichen simplex chronicus
- Neoplastic disorders: Squamous cell carcinoma
- Neurological disorders: Injury, entrapment, or neuropathy of the pudendal, genitofemoral, or ilioinguinal nerves, as well as Tarlov cysts.
- In cases of clitorodynia, the differential diagnosis should include irritation, compression, or damage to the pudendal nerve and the dorsal nerve of the clitoris
- Trauma-related causes: Straddle injuries, female genital cutting, and motor vehicle accidents
- Hormonal deficiencies: Estrogen deficiency
- Nonspecific symptoms: Vaginal burning and irritation
- Pelvic floor dysfunction: Muscle tension, weakness, or spasms, particularly relevant for clitorodynia
- Keratin pearls or clitoral hood adhesions: Accumulation of keratin between the clitoris and the clitoral hood can lead to irritation and pain
Diagnosis / Treatment / Management
Diagnosis
- This is usually a diagnosis of exclusion.
- The cotton swab test is used to help rule vulvodynia in or out.
- The clinician can start by asking the patiet where the pain is localized and using a cotton swab, the clinician systematically assesses pain by starting from the outer areas and moving inward toward the vestibule.
- The evaluation typically begins at the inner thigh, then proceeds to the labia majora, inner labial sulcus, clitoris, clitoral hood, perineum, and various points within the vestibule.
- The patient can rate their pain or the sensation that they are feeling at each site on a scale from 1 to 10.
- Pinprick test to assess for normal, hypo or hypersensitive reactions.
Treatment / Management
- Conservative Modalities:
- The treatment for vulvodynia is centered around self-care around avoiding irritant like tight clothing and wearing loose fitting and breathable clothing.
- Pyschotherapy, yoga, mindfulness, and neurostimulation are also treatments that can be considered.
- Pharmacology:
- Oral pain blocking meds (TCAs like nortriptyline can also be used, SNRIs, and anticonvulsants) can also be used to alleviated pain.
- Nortripryline has been reported to have the least amount of side effects.
- Topical pain meds directly to the vulva are typically compounded formulations that include lidocaine, estrogen, testosterone, or gabapentin, used individually or in combination.
- Physical therapy:
- For management of pelvic floor muscle dysfunction, including weakness and spasms.
- Surgery:
- Removing the parts of the affected vestibule is a last resort
- Minor surgical issues to address problems like keratin pearls can also be addressed.

- Can be associated with: Batholin gland abcess: pain, edema, and discharge on the labia
- Mucopurulent urethral discharge (yellow-green, possibly blood-tinged)
- Dysuria
- Increased urinary frequency.
Timeline of presentation:
- Incubation period: ~7-12 days after unprotected intercourse
- Early infection is often asymptomatic
- Weeks-months untreated: persistent cervicitis or urethritis
Differential
- Chalymdia
- Bacterial vaginosis
- Trichomoniasis
- Gential herpes
- Syphilis
- Urinary tract infections
- Pelvic inflammatory disease (PID)
Diagnosis / Treatment / Management
Diagnosis
- Nucleic Acid Amplification Test (NAAT), using urine samples or swabs (vaginal, cervical, urethral, anal, or throat)
Treatment / Management
- Preferred treatment:
- IM ceftriaxone
- Expedited partner therapy with cefixime
- Instruct the patient to avoid all sexual contact until: 7 days after treatment of the patient and their sexual partners, symptoms have resolved.

Trichomoniasis
Description / Key Features
- Diffuse, malodorous, yellow to greenish vaginal discharge
- The vaginal mucosa may be red, with a strawberry-appearing cervix
- There may or may not be vulvar irritation
Presentation Timeline
- Symptoms of trichomoniasis usually appear 5 to 28 days after exposure.
- Without treatment, the infection can persist for months or even years, while appropriate therapy typically clears symptoms within one week.
Differential Diagnosis
- Bacterial vaginosis
- Candidiasis
Diagnosis / Treatment / Management
Diagnosis
- Have a high index of suspicion for a T vaginalis infection in sexually active women seeking care for vaginal discharge and odor
- Careful inspection of saline prep is important
- Sometimes the T vaginalis is adherent to WBCs, making dx more difficult
- Look for moving shapes under the microscope
Treatment
- Metronidazole 500 mg BID for 7 days
- Tinidazole 2 g po

Atrophic Vaginitis
Description / Key Features
- Vaginal atrophy with the addition of itching and burning.
- Because the vaginal epithelium is thin, it is susceptible to becoming more irritated by commons kin irritant or local flora infection.
Presentation Timeline
- The onset cannot be predicted accurately for each person.
- They appear gradually.
- Whether occurring after surgical removal of the ovaries or through natural menopause, the changes are essentially the same, differing only in how quickly they develop.
Differential Diagnosis
- Lichen sclerosus
- Lichen planus
- Infectious vulvovaginitis
- Lichen simplex chronicus
Diagnosis / Treatment / Management
Diagnosis
- Clinically
- Through symptoms especially if women in menopausal state/age.
- Additional test to support are vaginal maturation index and vaginal pH.
Treatment / Management
- Systemic hormone therapy
- Topical Vaginal estrogen

Vaginal Atrophy
Description / Key Features
- The vaginal epithelium is an estrogen-dependent tissue.
- Vaginal atrophy occurs in all patients due to estrogen withdrawal, progressing from subtle changes in the maturation index to near-complete loss of the vaginal epithelium.
Presentation Timeline
- The onset cannot be predicted accurately for each person. They appear gradually.
- Whether occurring after surgical removal of the ovaries or through natural menopause, the changes are essentially the same, differing only in how quickly they develop.
Differential Diagnosis
- Trauma
- Irritation
- Lichen sclerosus
- Lichen planus
- Infectious vulvovaginitis
- Lichen simplex chronicus
- Vulvar cancer
- Extramammary Paget disease
Diagnosis / Treatment / Management
Diagnosis
- Diagnosed clinically through symptoms especially if women in menopausal state/age.
- Additional test to support are vaginal maturation index and vaginal pH.
Treatment / Management
- Systemic hormone therapy
- Topical Vaginal estrogen

Vulvitis
Description / Key Features
- Inflammation of the vulva or the genitals from either irritants, allergies, injuries or inflammation.
- Can cause burning, itching, vaginal discharge, thick, whitish patches of the skin or redness.
Presentation Timeline
- Onset of symtpoms may occur a few hours or days after exposure to an irritant or trigger.
Differential Diagnosis
- Vulvar dermatitis
- Lichen sclerosus
- Vulvovaginitis
- Yeast infetion
Diagnosis / Treatment / Management
Diagnosis
- Diagnosed via physicial and complete pelvic exam.
- Some test include urinalysis blood test, testing for STIs and a pap smear.
Treatment / Management
- Identify, remove and avoid irritates
- Hydrocortisone ointment
- Topical estrogen cream
- Taking regular sitz bath
