The facts most likely to be tested
Bartholin gland cysts arise from ductal obstruction of the vestibular glands located at the 4 and 8 o'clock positions of the vaginal introitus.
Asymptomatic cysts require no treatment and can be managed with expectant management or sitz baths.
Symptomatic or infected cysts that progress to an abscess present with severe, unilateral vulvar pain and a fluctuant, tender mass.
The primary treatment for a symptomatic Bartholin gland abscess is incision and drainage (I&D) with Word catheter placement to prevent recurrence.
Marsupialization is the preferred surgical intervention for recurrent Bartholin gland cysts or abscesses.
Empiric antibiotic therapy is only indicated if there are signs of cellulitis, systemic infection, or if the patient is at high risk for methicillin-resistant Staphylococcus aureus (MRSA).
New-onset Bartholin gland masses in patients older than 40 years require biopsy to rule out vulvar carcinoma.
Vignette unlocked
A 28-year-old female presents to the urgent care clinic complaining of a painful, enlarging mass on her left labia that has made walking and sitting difficult for the past 3 days. On physical examination, there is a tender, fluctuant, 3-cm mass located at the 4 o'clock position of the vaginal introitus with surrounding erythema and edema. The patient is afebrile and has no systemic symptoms. She has no significant past medical history.
What is the most appropriate initial management for this patient?
Incision and drainage with Word catheter placement
The patient presents with a classic Bartholin gland abscess, which requires drainage and placement of a Word catheter to maintain patency and prevent recurrence, as described in the fourth bet.

Etiology / Epidemiology
Common in reproductive-age women due to ductal obstruction. Risk factors include poor hygiene and vulvovaginitis.
Clinical Manifestations
Painless or tender unilateral vulvar mass at the 4 or 8 o'clock position. Abscess presents with severe pain and erythema.
Diagnosis
Primarily a clinical diagnosis. Culture is the gold standard for abscesses to identify Neisseria gonorrhoeae.
Treatment
Asymptomatic cysts require no treatment. Symptomatic abscesses require incision and drainage with a Word catheter.
Prognosis
High recurrence rate if the duct remains obstructed. Marsupialization is indicated for recurrent cases.

Epidemiology & Etiology
Occurs most frequently in women aged 20–29 years. Obstruction of the distal duct leads to fluid accumulation. While often sterile, secondary infection can occur, frequently involving E. coli or polymicrobial flora.
Pertinent Anatomy
The glands are located in the superficial perineal pouch. They secrete mucus into the vestibule via ducts located at the 4 and 8 o'clock positions of the vaginal introitus. Obstruction leads to cystic dilation of the gland.
Pathophysiology
Ductal blockage prevents normal mucus drainage, resulting in a cyst. If the cyst becomes colonized by bacteria, it progresses to an abscess. Systemic sepsis is rare but possible if the infection spreads to surrounding soft tissues.
Clinical Manifestations
Patients typically present with a unilateral, tender, fluctuant mass. Abscesses cause severe pain that interferes with walking or sitting. Red flags include fever, cellulitis, or systemic signs of infection requiring parenteral antibiotics.
Diagnosis
Diagnosis is based on physical exam findings of a vulvar mass. If an abscess is suspected, a culture of the purulent drainage is the gold standard to rule out Neisseria gonorrhoeae or Chlamydia trachomatis.
Treatment
Asymptomatic cysts require only sitz baths and observation. For abscesses, incision and drainage is the treatment of choice, often followed by placement of a Word catheter to maintain patency. Do not perform simple incision and closure as it leads to high recurrence rates.
Prognosis
Recurrence is common if the ductal opening is not maintained. Marsupialization is the definitive surgical procedure for patients with recurrent cysts or abscesses. Monitor for signs of cellulitis post-procedure.
Differential Diagnosis
Epidermal inclusion cyst: usually midline and non-tender
Lipoma: soft, non-tender, and mobile subcutaneous mass
Hidradenitis suppurativa: multiple recurrent nodules with sinus tracts
Vulvar cancer: firm, irregular, or ulcerated mass in older patients
Inguinal hernia: reducible mass that may extend into the labia
