Differential Diagnosis for Vulva Itching and Redness

Single Most Likely Diagnosis

  • Candidiasis (Vulvovaginal Yeast Infection): This is often the most common cause of vulva itching and redness, especially in women of reproductive age. The symptoms can include intense itching, redness, swelling, and a white, clumpy discharge.

Other Likely Diagnoses

  • Contact Dermatitis: An allergic reaction or irritation from soaps, detergents, or other products can cause vulvar itching and redness. Symptoms can vary but often include itching, burning, and visible skin changes.
  • Lichen Sclerosus: A chronic skin condition that can cause itching, pain, and scarring on the vulva. It's more common in postmenopausal women and can lead to significant discomfort and changes in the vulvar architecture.
  • Lichen Planus: An inflammatory condition that can affect the vulva, causing itching, burning, and sometimes pain. It can lead to scarring and changes in the vulvar appearance.

Do Not Miss Diagnoses

  • Squamous Cell Carcinoma or Other Vulvar Cancers: Although rare, vulvar cancer can present with itching and redness. Early detection is crucial for effective treatment, making it a diagnosis that should not be missed.
  • Herpes Simplex Virus (HSV): Genital herpes can cause severe itching, redness, and painful blisters. It's a sexually transmitted infection that requires specific antiviral treatment.
  • Syphilis: A sexually transmitted infection that can cause a variety of symptoms, including vulvar itching and redness, especially in its secondary stage.

Rare Diagnoses

  • Psoriasis: Although more commonly associated with other body areas, psoriasis can rarely affect the vulva, causing itching, redness, and scaly patches.
  • Darier Disease: A rare genetic disorder that affects the skin, sometimes causing vulvar lesions and itching.
  • Zinc Deficiency: Can lead to skin lesions and itching, including in the vulvar area, though this is relatively rare and usually associated with other systemic symptoms.
