Vaginal Cysts: Symptoms, Types, Causes and Treatment

Vaginal cysts are an important, though relatively uncommon, finding in gynecological practice. While many are discovered incidentally and are benign, their presence can be a source of confusion, anxiety, and, at times, discomfort for those affected. Understanding the symptoms, types, causes, and available treatments for vaginal cysts is crucial for both patients and healthcare providers. This article provides a comprehensive, evidence-based overview, guiding you through the key aspects of vaginal cysts using current research and clinical insight.

Symptoms of Vaginal Cysts

Vaginal cysts often go unnoticed, but when they do cause symptoms, these can range from mild irritation to more disruptive problems. Recognizing the signs can help prompt timely evaluation and appropriate management.

Symptom	Description	Frequency/Notes	Source(s)
Pressure	Sensation of fullness or heaviness	Most common symptom	1
Voiding Issues	Difficulty urinating	Due to cyst pressing on urethra	1 6
Dyspareunia	Pain during intercourse	Less common	1 3 5
Swelling/Mass	Noticeable lump in the vagina	Common presenting complaint	3 4
Discharge	Fluid leaking from cyst	Occasionally reported	5
Pain	Localized discomfort	Especially if cyst is inflamed	1 5 10
Asymptomatic	No symptoms at all	Frequently the case	1 4 9 10

Table 1: Key Symptoms of Vaginal Cysts

Understanding the Symptoms

Most vaginal cysts are found by chance during pelvic exams since they often don’t cause symptoms at all. In fact, studies have shown that up to 77% of cases are asymptomatic and discovered incidentally during evaluation for unrelated issues 4. However, when symptoms do occur, they can cause significant distress or discomfort.

Common Presentations

• Pressure or Heaviness: This is the most frequently reported symptom, with more than half of patients experiencing a sensation of pressure, especially if the cyst is on the anterior vaginal wall 1.
• Voiding Dysfunction: Cysts pressing against the urethra can lead to difficulty urinating or even urinary obstruction. This is more likely with larger cysts or those located near the urethra 1 6.
• Dyspareunia: Pain during intercourse, while less common, can occur if the cyst is large or positioned where it’s irritated during sexual activity 1 3 5.
• Visible or Palpable Mass: Many women first notice a cyst as a lump or swelling in the vagina, particularly during self-examination or insertion of tampons 3 4.
• Pain and Inflammation: Occasionally, cysts become inflamed or infected, resulting in pain, redness, and sometimes local warmth 1 5 10.
• Vaginal Discharge: Rarely, cysts may leak fluid, leading to unusual vaginal discharge 5.

When to Seek Medical Advice

Most cysts are harmless, but attention should be paid to cysts that are painful, rapidly growing, fixed (not movable), or associated with bleeding. These features warrant further evaluation to rule out rare but serious conditions 10. Women over 40 with new cysts should also have a thorough assessment.

Types of Vaginal Cysts

Vaginal cysts are classified based on their origin and histological characteristics. Understanding the different types helps guide diagnosis and management.

Cyst Type	Origin/Epithelium	Common Location	Source(s)
Müllerian	Müllerian duct (columnar/cuboidal)	Lateral/posterior wall	3 4 5 7
Epidermal Inclusion	Surface mucosa, squamous epithelium	Posterior/lateral wall	3 4 7
Gartner’s Duct	Mesonephric duct, cuboidal lining	Anterior/lateral wall	3 4 7 9
Bartholin’s Duct	Bartholin gland duct, mucinous	Lower vaginal wall	3 4 7 10
Endometriotic	Endometrial tissue	Variable	3 4
Urothelial/Other Rare	Urothelial or other origins	Variable	2 7

Table 2: Main Types of Vaginal Cysts

Overview of Major Types

Vaginal cysts can be either congenital (present from birth) or acquired. The main types are:

Müllerian Cysts

• Origin: Remnants of the Müllerian ducts, which form parts of the female reproductive tract.
• Features: Lined by columnar or cuboidal epithelium similar to endocervical tissue.
• Prevalence: Among the most common, comprising about 30-44% of cases 3 4.
• Symptoms: Usually asymptomatic, but can present as a palpable mass or cause discomfort if large 3 5.

Epidermal Inclusion Cysts

• Origin: Trapped surface mucosa, often after trauma such as childbirth, episiotomy, or surgery.
• Features: Lined by squamous epithelium.
• Prevalence: About 23-25% of vaginal cysts 3 4.
• Location: Frequently found at sites of previous vaginal injury 3.

Gartner’s Duct Cysts

• Origin: Remnants of the mesonephric (Wolffian) duct.
• Features: Lined by cuboidal epithelium, typically located along the lateral walls.
• Prevalence: Uncommon, about 10-12% 3 4.
• Symptoms: Most are asymptomatic; large cysts can cause urinary symptoms 9.

Bartholin’s Duct Cysts

• Origin: Obstruction of the Bartholin gland duct.
• Features: Lined by mucinous, transitional, or squamous epithelium.
• Prevalence: 7-28% of cases 3 4.
• Symptoms: More likely to be symptomatic and associated with inflammation 4 10.

Endometriotic and Other Rare Cysts

• Origin: Endometrial tissue or urothelial tissue.
• Features: Rare, variable presentation 2 3 4.

How Are They Identified?

• Clinical Examination: Location and feel can provide clues, but definitive diagnosis often requires histological analysis 2 4.
• Imaging: Ultrasound and MRI can help differentiate cyst types, especially for deeper or complex lesions 1 6 10.

Causes of Vaginal Cysts

The development of vaginal cysts can be traced to several different processes, both congenital and acquired. Understanding these causes helps clarify why these cysts occur and which patients may be at risk.

Cause	Description	Typical Cyst Types	Source(s)
Embryologic Remnant	Tissue left from fetal development	Müllerian, Gartner’s Duct	6 7 9 10
Trauma/Surgery	Injury or incision leads to inclusion cysts	Epidermal Inclusion	3 4 6
Ductal Obstruction	Blockage of gland ducts	Bartholin’s Duct	4 10
Ectopic Tissue	Endometrial tissue outside uterus	Endometriotic	3 4
Unknown/Other	Unclear or mixed causes	Unclassified/Rare types	4 7

Table 3: Main Causes of Vaginal Cysts

Embryological Origins

Many vaginal cysts result from remnants of embryologic structures that fail to regress during development:

• Müllerian Cysts: Arise from Müllerian duct remnants, which can persist anywhere along the vaginal wall 6 9.
• Gartner’s Duct Cysts: Develop from Wolffian duct remnants; typically found on the lateral or anterior vaginal wall 6 9.

Acquired Causes

Some cysts are not present at birth but develop later due to:

• Trauma or Surgery: Injury to the vaginal wall, such as from childbirth, episiotomy, or gynecologic procedures, can trap surface tissue, leading to epidermal inclusion cysts 3 4 6.
• Ductal Obstruction: Blockage of gland ducts, especially the Bartholin gland, results in cyst formation due to fluid accumulation 4 10.
• Ectopic Tissue: Endometriotic cysts occur when endometrial tissue implants in the vaginal wall, often related to pelvic endometriosis 3 4.

Other Contributing Factors

• Inflammation/Infection: Chronic inflammation may play a role, particularly in Bartholin’s cysts, which are frequently associated with infection and inflammation 4 10.
• Unclassified/Unknown: Some rare cysts have no clearly identifiable cause, reflecting the complexity of vaginal embryology and healing 4 7.

Treatment of Vaginal Cysts

The approach to treating vaginal cysts is guided by symptoms, cyst type, and patient preferences. Most cysts are benign and do not require intervention, but treatment is available for those causing discomfort or complications.

Treatment Option	When Used	Main Advantages	Source(s)
Observation	Asymptomatic, benign cysts	Avoids unnecessary surgery	1 9 10
Surgical Excision	Symptomatic or large cysts	Definitive, low recurrence	1 3 4 6 10
Drainage/Fenestration	Infected or inflamed cysts	Quick symptom relief	1 10
Imaging/Follow-up	Complex or suspicious cysts	Ensures accurate diagnosis	1 6 10

Table 4: Main Treatment Approaches for Vaginal Cysts

Observation and Conservative Management

• Most vaginal cysts are asymptomatic and benign.
• Observation is appropriate for small, non-bothersome cysts, particularly Gartner’s duct cysts, which can remain stable for many years without causing problems 9 10.
• Regular follow-up may be recommended to monitor for changes in size or symptoms.

Surgical Treatment

• Excision is the treatment of choice for symptomatic cysts, those growing in size, or when malignancy cannot be excluded 1 3 4 6.
  • Outcomes: Surgery is typically curative, with low rates of recurrence and minimal complications.
  • Procedure: Most cases are outpatient, and recovery is rapid. Complications are rare but can include bleeding or infection 1.

Drainage and Other Procedures

• Drainage or fenestration may be performed for infected or inflamed cysts to provide immediate relief 1 10.
• Biopsy may be indicated if there is uncertainty about the diagnosis or suspicion of malignancy.

Imaging and Further Evaluation

• Imaging (ultrasound or MRI) is valuable for complex, deep, or recurrent cysts, or when the diagnosis is unclear 1 6 10.
• Referral to a specialist may be recommended for unusual presentations or if malignancy is suspected.

Special Considerations

• Older Women or Suspicious Cysts: Any fixed, rapidly enlarging, or painful cyst in a woman over 40 should be evaluated carefully to exclude rare cases of malignancy 10.
• Patient Preference: Treatment decisions should always consider the patient’s comfort, concerns, and personal preferences.

Conclusion

Vaginal cysts are generally benign and often discovered incidentally, but understanding their potential symptoms, types, causes, and treatment options is crucial. Most require little or no intervention, but some may need further evaluation or surgical removal, especially if symptomatic.

Key takeaways from this article:

• Vaginal cysts are most commonly asymptomatic but can cause pressure, pain, or urinary symptoms when larger or inflamed.
• The main types include Müllerian, epidermal inclusion, Gartner’s duct, and Bartholin’s duct cysts, each with distinct origins.
• Causes range from embryological remnants to trauma, surgery, or ductal obstruction.
• Most cysts can be safely observed, but surgical excision is effective for symptomatic or suspicious cases.
• Imaging and histological assessment play key roles in diagnosis and management when the cyst is complex or atypical.

If you notice a lump, experience discomfort, or have concerns about vaginal cysts, consult a healthcare provider for evaluation and personalized advice.
