What are the Causes of Sebaceous Cysts of Vulva? (Etiology)

  • Sebaceous Gland Cysts of Vulva occur due to obstruction of the oil glands or sebaceous glands causing it to dilate and get swollen
  • It is important to note that Vulvar Sebaceous Cysts are not caused by any sexually transmitted disease

What are the Signs and Symptoms of Sebaceous Cysts of Vulva?

A majority of the cysts are small-sized and asymptomatic, presenting no significant signs and symptoms. In some cases, the following signs and symptoms of Sebaceous Cysts of Vulva may be noted:

  • Presence of a fluid-filled cyst that appears as a tiny bump; in most cases, more than one cyst may be present
  • The cysts may be of varying sizes; most cysts are very small (about a few mm), while some may grow larger
  • Redness and tenderness; usually no pain is felt
  • Large sizes may cause discomfort and pain
  • Fluid drainage from the cyst with a foul, smelly discharge
  • Pain or discomfort while using a tampon, during sex
  • Discomfort while walking or sitting
  • Sometimes, it may also cause itching and painful urination

How is Sebaceous Cysts of Vulva Diagnosed?

A diagnosis of Sebaceous Gland Cysts of Vulva may involve the following steps:

  • Evaluation of the individual’s medical history and a thorough physical (pelvic) examination. Usually, a pelvic (visual) exam is sufficient to ensure a diagnosis of the condition
  • Tests to rule out sexually-transmitted infections (if necessary)
  • Biopsy of the mass: It is the process of removing tissue for examination. In the case of sebaceous gland cyst, a complete excision and removal of the lesion can help in the process of a biopsy, as well as be a means for treating the condition
  • Occasionally, since the cyst is fluctuant (due to accumulation of fluid), a fine needle aspiration of the cyst contents may be performed
    • Fine needle aspiration (FNA) biopsy: A very fine and hollow needle is inserted where the cyst is noticed; the fluid contained within the cyst is withdrawn. The extracted sample is sent for further pathological examination
    • If the healthcare provider suspects an infection process, then culture studies on the cyst aspirate may be performed

Many clinical conditions may have similar signs and symptoms. Your healthcare provider may perform additional tests to rule out other clinical conditions to arrive at a definitive diagnosis.

What are the possible Complications of Sebaceous Cysts of Vulva?

No significant complications of Sebaceous Gland Cysts of Vulva are noted, because it is a benign condition. However, the following may be observed in some cases:

  • Abscess formation resulting in infections; this may result in associated signs and symptoms including fever
  • Severe pain during sex, if the cysts are infected and painful
  • The cysts may rupture and bleed resulting in secondary infections
  • Damage to the muscles, vital nerves, and blood vessels, during surgery
  • Post-surgical infection at the wound site is a potential complication
  • Recurrence of the cyst

How is Sebaceous Cysts of Vulva Treated?

  • Sitz bath: Immersing oneself several times in a tub filled with warm water for a period of 3-4 days may cause the cyst to break and the fluid will drain on its own. This therapy may not be effective for all individuals. The healthcare provider will advise if the therapy is appropriate for the individual
  • Application of topical creams and gels, to bring relief from the symptoms and to provide a measure of comfort
  • Stoppage of soaps and body creams that have strong chemicals in them; use of milder alternatives
  • Some healthcare providers may advocate an increase in vitamins A and B rich foods that can help with the healing process
  • Use of clean cotton underwear; avoiding synthetic and tight-fitting clothes for a period of time
  • Maintain proper personal hygiene, especially in the genital region
  • In some cases, the cysts may get secondarily infected. If bacteria is the cause of infection, it may be treated through antibiotics
  • If the antibiotics does not clear the infection, then an abscess drainage through a surgical procedure may be performed
  • Surgical intervention with complete excision can result in a complete cure
  • Post-operative care is important: Minimum activity level is to be ensured until the surgical wound heals
  • Follow-up care with regular screening and check-ups are important
