Differential Diagnosis for Palpable Lumps in the Vulvar Area

Single Most Likely Diagnosis

  • Bartholin's cyst: This is the most common cause of a palpable lump in the vulvar area, especially if the lump is located near the vaginal opening. Bartholin's glands can become obstructed, leading to cyst formation, which can be painful and may become infected.

Other Likely Diagnoses

  • Lipoma: A benign tumor composed of fat tissue, which can occur in the vulvar area and present as a palpable lump.
  • Vulvar abscess: An accumulation of pus in the vulvar tissue, often resulting from an infection, which can present as a painful lump.
  • Folliculitis or furuncle: Inflammation of the hair follicles or a boil in the vulvar area, which can cause a palpable lump.
  • Vulvar cysts (other than Bartholin's): Such as epidermal inclusion cysts or sebaceous cysts, which can occur in the vulvar area.

Do Not Miss Diagnoses

  • Squamous cell carcinoma or other vulvar cancers: Although less common, these can present as a lump in the vulvar area and are critical to diagnose early due to their potential for malignancy.
  • Genital herpes: Can cause painful lesions that might be mistaken for lumps, especially if they become secondarily infected.
  • Lymphogranuloma venereum (LGV): A sexually transmitted infection that can cause lymphadenopathy (swollen lymph nodes) in the groin area, which might be felt as lumps.

Rare Diagnoses

  • Vulvar sarcomas: Rare malignant tumors originating from connective tissue in the vulva.
  • Neurofibromas: Benign nerve sheath tumors that can occur in the vulvar area, more commonly in patients with neurofibromatosis.
  • Vulvar endometriosis: Rarely, endometrial tissue can implant in the vulvar area, leading to painful lumps, especially during menstruation.
  • Hydrocele of the vulva: A rare condition where fluid accumulates in a sac in the vulvar area, similar to a hydrocele in men.
