Differential Diagnosis for Vaginal Itching

Single Most Likely Diagnosis

  • Vulvovaginal Candidiasis: This is the most common cause of vaginal itching, often associated with a white, cottage cheese-like discharge. It's a fungal infection that can be triggered by antibiotics, hormonal changes, or diabetes.

Other Likely Diagnoses

  • Bacterial Vaginosis (BV): Characterized by an imbalance of the normal vaginal flora, leading to an overgrowth of bacteria. Symptoms include itching, burning, and a fishy odor.
  • Vaginal Atrophy: Common in postmenopausal women due to decreased estrogen levels, leading to thinning and drying of the vaginal walls, which can cause itching and discomfort.
  • Allergic Contact Dermatitis: An allergic reaction to soaps, douches, or other products used in the genital area, causing itching, redness, and irritation.
  • Trichomoniasis: A sexually transmitted infection caused by a parasite, leading to itching, burning, and a foul-smelling discharge.

Do Not Miss Diagnoses

  • Cervical Cancer: Although rare, cervical cancer can cause vaginal itching among other symptoms like abnormal vaginal bleeding. It's crucial to not miss this diagnosis due to its severe implications.
  • Lichen Sclerosus: A chronic skin condition that can cause itching, pain, and scarring in the genital area. If left untreated, it can increase the risk of cancer.
  • Herpes Simplex Virus (HSV): A sexually transmitted infection that can cause itching, burning, and painful blisters in the genital area.

Rare Diagnoses

  • Vulvar Intraepithelial Neoplasia (VIN): A rare condition where abnormal cells are found on the vulva, which can cause itching and may progress to cancer if not treated.
  • Paget's Disease of the Vulva: A rare skin condition that can cause itching, redness, and a rash on the vulva, and may be associated with an underlying cancer.
  • Desquamative Inflammatory Vaginitis (DIV): A rare condition characterized by severe vaginal inflammation, causing itching, burning, and a purulent discharge.
