Reproductive
Bartholin gland cyst and abscess
The Bartholin glands (greater vestibular glands) are paired, pea-sized structures located at the 4 and 8 o'clock positions of the vaginal introitus. They secrete mucus for vaginal lubrication. Obstruction of the duct → cyst formation; secondary infection of the cyst → abscess.
Board pearl: Bartholin gland cysts/abscesses are almost always unilateral. A painless, non-tender mass = cyst; a painful, warm, fluctuant, erythematous mass = abscess.
Next best step: Clinical exam is sufficient for diagnosis in reproductive-age women. In women >40, biopsy to rule out Bartholin gland carcinoma.

— Painless or mildly uncomfortable unilateral vulvar swelling
— May be discovered incidentally on exam
— Dyspareunia or discomfort while sitting/walking if large (>3–4 cm)
— Often waxes and wanes in size
— Rapid onset (24–72 hours) of painful, progressive vulvar swelling
— Severe tenderness, difficulty sitting/walking
— May have associated fever, malaise
— History of preceding cyst that acutely worsened
— Spontaneous rupture may occur with drainage of purulent material and temporary relief
History red flags to elicit:
Key distinction: Recurrent or persistent masses in women >40 warrant biopsy to exclude adenocarcinoma of the Bartholin gland.

— Smooth, round, non-tender, fluctuant mass
— Overlying skin normal or mildly stretched
— Size ranges from 1–5 cm
— Medial displacement of the labium minus on the affected side
— Tender, warm, erythematous, fluctuant mass
— Surrounding cellulitis may be present
— Purulent drainage if spontaneously ruptured
— Inguinal lymphadenopathy may be present
Board pearl: No imaging is needed for diagnosis in a typical presentation. The location (posterolateral introitus) and clinical features are sufficient.
— Skene gland cyst (anterior/periurethral)
— Gartner duct cyst (anterolateral vaginal wall)
— Vulvar lipoma or sebaceous cyst (superficial, non-vestibular)
— Vulvar malignancy (hard, fixed, irregular mass in older patient)

— Wound culture of abscess contents → guides antibiotic therapy if needed; often polymicrobial (anaerobes, aerobes, rarely GC/chlamydia)
— GC/chlamydia NAAT testing: obtain if STI risk factors present, abscess in young sexually active patient
— CBC: only if signs of systemic infection (fever, leukocytosis suspected)
— Blood cultures: if sepsis suspected (rare)
— Generally unnecessary
— Ultrasound may help if diagnosis is uncertain — will show well-circumscribed cystic structure or complex fluid collection
— Consider pelvic MRI only if concern for deep soft-tissue extension or malignancy
Next best step: In a typical reproductive-age woman with a classic posterolateral vulvar mass → proceed directly to treatment without additional workup.
Board pearl: Routine culture of cyst fluid (non-infected) is low yield and not recommended.

Indications for biopsy:
Histology:
Board pearl: An excision biopsy at the time of treatment (e.g., during marsupialization or excision) is the standard approach for women >40 — do not simply drain and forget.
Key distinction: Bartholin gland carcinoma may mimic a benign cyst; always maintain a low threshold for biopsy in postmenopausal women.

— Observation only — no treatment required
— Warm sitz baths (15–20 min, 3–4×/day) may promote spontaneous drainage
— Patient education on self-care and when to return
— Word catheter placement (first-line office procedure)
— Alternatively: marsupialization
— First-line: Incision and drainage (I&D) with Word catheter placement
— Marsupialization is an alternative, especially for recurrent abscesses
— Antibiotics alone are insufficient — drainage is essential
— Antibiotics added to I&D only if: surrounding cellulitis, immunocompromised patient, suspected STI, systemic infection (fever, sepsis)
Next best step for a Bartholin abscess: I&D with Word catheter insertion — this is the most commonly tested answer on boards.
Board pearl: Needle aspiration alone has a high recurrence rate (~38%) and is NOT recommended as definitive management.

The Word catheter is a small inflatable-bulb catheter placed through a stab incision into the cyst/abscess cavity to create a fistulous tract (epithelialized new duct) for permanent drainage.
Procedure:
Outcomes:
Board pearl: The Word catheter is left in for 4–6 weeks — premature removal ↑ recurrence risk. The stab incision must be placed on the mucosal (medial) surface to create a functional new ostium.

— Elliptical incision into cyst wall → suture cyst wall edges to surrounding vestibular skin → creates permanent opening
— Performed under local or regional anesthesia; usually in OR or procedure suite
— Lower recurrence than simple I&D (~5–10%)
— Preferred for recurrent cysts/abscesses
— Avoid during active infection if possible (↑ wound breakdown risk)
— Reserved for: recurrent disease after marsupialization failure, suspicion of malignancy (age >40), patient preference
— Risks: significant bleeding (highly vascular area), scarring, dyspareunia, longer recovery
— Not first-line due to surgical morbidity
— Silver nitrate gland ablation
— CO₂ laser ablation
— Jacobi ring catheter
Key distinction: Marsupialization > Word catheter for recurrent disease. Excision is last resort, not first-line.
Next best step for a second recurrence after Word catheter: Marsupialization.

— First trimester: Warm sitz baths for asymptomatic cysts; Word catheter or I&D for abscess under local anesthesia — safe and preferred
— Second trimester: Same as first; marsupialization can be performed if needed
— Third trimester/near term: Abscess should be drained to avoid obstruction of the birth canal; large cysts may also warrant drainage before delivery
— Safe: amoxicillin-clavulanate, cephalosporins, clindamycin
— Avoid: fluoroquinolones (teratogenic), doxycycline (bone/tooth effects after 1st trimester)
— Treat concurrent GC/chlamydia with ceftriaxone + azithromycin
Board pearl: Do not delay drainage of a Bartholin abscess in pregnancy — the procedure is safe under local anesthesia at any gestational age. An untreated abscess near term may necessitate cesarean if it obstructs the vaginal canal.

— Bartholin gland cysts are extremely rare before puberty (glands not functional until puberty)
— A vulvar mass in a prepubertal child → consider other etiologies: labial adhesions, urethral prolapse, rhabdomyosarcoma, sexual abuse
— If Bartholin cyst occurs in an adolescent → manage as in adults
— Any new Bartholin gland mass must be biopsied to exclude carcinoma
— Bartholin gland carcinoma: adenocarcinoma most common histologic type; treatment is wide local excision ± inguinal lymph node dissection ± radiation
— Do NOT simply drain and discharge without tissue sampling
— Higher risk of polymicrobial and atypical infections (MRSA, fungal)
— Lower threshold for empiric antibiotics after I&D
— Broader-spectrum coverage may be necessary
— Wound cultures are especially important to guide therapy
Board pearl: Vulvar mass in a postmenopausal woman = biopsy is mandatory, regardless of clinical appearance.

— Most common complication
— Simple I&D: ~38% recurrence
— Word catheter: 5–15%
— Marsupialization: 5–10%
— Excision: <5% but highest surgical morbidity
— Cellulitis of surrounding vulvar tissue
— Sepsis (rare, usually in immunocompromised patients)
— Necrotizing fasciitis of the vulva (rare but life-threatening) — suspect if rapid spread, crepitus, disproportionate pain, systemic toxicity → emergent surgical debridement + IV broad-spectrum antibiotics
— Fistula formation (rare)
— Bleeding (Bartholin gland area is highly vascular)
— Word catheter displacement → recurrence
— Dyspareunia after excision or marsupialization
— Scarring/vulvar asymmetry after excision
Board pearl: If a patient with a drained Bartholin abscess develops rapidly worsening pain with dusky skin changes, crepitus, or hemodynamic instability → suspect necrotizing fasciitis → emergent wide surgical debridement is the next best step.

— Abscess not improving 48–72 hours after I&D with Word catheter → re-evaluate; consider repeat drainage, broader antibiotics, or marsupialization
— ≥2 recurrences → referral for marsupialization or excision
— Fever >38.5°C, tachycardia, leukocytosis → admit for IV antibiotics + I&D
— Sepsis criteria → aggressive resuscitation, blood cultures, IV broad-spectrum antibiotics, emergent drainage
— Refer to gynecologic oncology for suspected Bartholin gland carcinoma
— Solid mass, irregular borders, fixation to underlying tissue, lymphadenopathy
— Emergent surgical consultation
— Wide debridement → ICU-level care
— IV vancomycin + piperacillin-tazobactam + clindamycin (for toxin inhibition)
Next best step if outpatient I&D fails and abscess recurs within weeks: Marsupialization under regional/general anesthesia, with wound culture and tissue biopsy if age >40.

— Location: periurethral, anterior vestibule (12 o'clock position)
— May cause dysuria, urinary retention
— Key distinction: Anterior vs. posterior (Bartholin = posterolateral)
— Superficial, movable, non-tender, on labium majus (cutaneous)
— Not vestibular in origin
— No mucosal drainage
— Mesonephric (Wolffian) duct remnant
— Location: anterolateral vaginal wall, not introitus
— Usually incidental finding
— Common in pregnancy; bluish, compressible
— Not fluctuant or cystic
— Inguinal/labial swelling; mesonephric remnant
— Firm, fixed, irregular; age >40
— Biopsy is diagnostic
Board pearl: Location is the single most important distinguishing feature — Bartholin = posterolateral introitus (4/8 o'clock), Skene = periurethral (anterior).

— Can arise from folliculitis, hidradenitis suppurativa, or infected inclusion cyst
— Location: anywhere on labia or mons; NOT specifically at the posterolateral introitus
— Management: I&D; no Word catheter needed
— Chronic, recurrent abscesses and sinus tracts in apocrine gland–bearing skin (inguinal folds, labia majora, axillae)
— Multiple lesions, comedones, scarring
— Not a single vestibular mass
— Painful vesicles/ulcers, NOT a cystic mass
— Systemic symptoms (fever, myalgias) with primary outbreak
— Pruritus, erythema, discharge — no mass
— Postpartum, wound site infection — contextual history
Key distinction: A single, well-defined, fluctuant mass at the 4 or 8 o'clock position of the introitus = Bartholin gland pathology until proven otherwise.

— STI prevention (condoms, PrEP counseling) may reduce infection-related duct obstruction
— Good vulvar hygiene
— Prompt treatment of vulvovaginal infections
— Word catheter (left in 4–6 weeks) has lower recurrence than simple I&D
— Marsupialization for recurrent disease
— Excision only for multiply recurrent cases
— Warm sitz baths after treatment to promote drainage
— No routine screening exists
— Clinical vigilance in women >40: any new, recurrent, or persistent Bartholin gland mass → biopsy
— Bartholin gland carcinoma is so rare that screening in the general population is not warranted
Board pearl: STI screening (GC/chlamydia) should be performed in sexually active women presenting with a Bartholin abscess, especially if <25 years or with high-risk history, even though most abscesses are polymicrobial and not purely STI-related.

— Follow-up at 1–2 weeks to confirm catheter in place and assess healing
— Catheter removal at 4–6 weeks
— Re-evaluate at 6–8 weeks for recurrence
— Instruct patient to return immediately if catheter falls out prematurely, mass recurs, or signs of reinfection develop
— Follow-up at 1–2 weeks for wound check
— Sitz baths to keep the new ostium patent
— Monitor for recurrence over subsequent months
— Wound check at 1–2 weeks
— Evaluate for complications: hematoma, infection, wound dehiscence
— Assess for dyspareunia at 6-week postoperative visit
— Recurrence can occur months to years later; patient should perform vulvar self-exam
— Annual well-woman exam includes vulvar inspection
— Women >40 with recurrence → repeat biopsy with each new episode
Next best step if Word catheter falls out at 1 week and mass recurs: Replace Word catheter or proceed to marsupialization.

— Discuss all treatment options (observation, Word catheter, marsupialization, excision) with risks, benefits, and recurrence rates
— Patients should understand that drainage procedures carry a recurrence risk and may need to be repeated
— Consent for biopsy in women >40 — explain the rationale for cancer exclusion
— Vulvar exams can be distressing; offer chaperone, explain each step
— History of sexual trauma → trauma-informed approach, patient control over exam
— Adolescents: ensure confidentiality regarding STI testing per state law; parental consent requirements vary
— Vulvar trauma can result from intimate partner violence — screen in a private, nonjudgmental manner
— Do not prescribe antibiotics for uncomplicated Bartholin abscess after adequate I&D in an immunocompetent patient — drainage alone is curative
— Antibiotics are overused in this setting
Board pearl: Antibiotics without drainage will not resolve a Bartholin abscess — the definitive treatment is always procedural (I&D).

Board pearl: The posterolateral introital location of a vulvar mass + reproductive-age woman = Bartholin gland cyst/abscess until proven otherwise.
