Vaginal Yeast Infection Can Present with Itchiness as the Sole Symptom

Yes, a vaginal yeast infection can present with vulvar itching as the only symptom. Itching is actually the symptom most specific to vulvovaginal candidiasis (VVC), and in some cases, it may be the sole manifestation of the infection 1, 2.

Clinical Presentation of Vaginal Yeast Infections

Vulvovaginal candidiasis typically presents with various symptoms, but their presence and severity can vary significantly between patients:

• Vaginal itching is the most specific symptom of VVC and may be the only complaint in some cases 1, 2
• Other common symptoms that may or may not be present include:
  • Vaginal soreness, swelling, and burning 1
  • Dyspareunia (painful intercourse) 1
  • Dysuria (painful urination) 1
  • Vaginal discharge (typically thick, white, and resembling cottage cheese) 1, 3

Diagnostic Considerations

When a patient presents with vulvar itching as the only symptom, healthcare providers should consider the following:

• Self-diagnosis of yeast infection based solely on itching is unreliable and can lead to inappropriate treatment 4
• Proper diagnosis should include:
  • Clinical evaluation of symptoms
  • Laboratory confirmation through microscopy, culture, or newer molecular assays 1
• A study examining self-reported symptoms found that vulvar itching with a severity score of 5 or greater (on a Likert scale) was a significant independent predictor of a positive yeast culture result 5
• Vaginal pH testing can help differentiate VVC (typically ≤4.5) from other causes of vaginitis 6, 7

Differential Diagnosis

When evaluating a patient with vulvar itching as the only symptom, consider these alternative diagnoses:

• Bacterial vaginosis (usually presents with discharge and odor, but can have some itching) 7
• Trichomoniasis (typically has more discharge and odor) 7
• Atrophic vaginitis (more common in postmenopausal women) 7
• Contact or allergic dermatitis of the vulva 7, 8
• Lichen sclerosus or other dermatologic conditions 8

Management Approach

For patients presenting with vulvar itching that is suspected to be due to VVC:

• Confirmation of diagnosis is recommended before treatment, especially for first episodes 1, 4
• Treatment options include:
  • Oral fluconazole 150 mg as a single dose 9
  • Topical azole treatments such as miconazole 2% cream applied intravaginally for 7 days 3
  • For pregnant women, only topical azoles are recommended 6

Important Considerations

• Approximately 10-20% of women normally harbor Candida species in the vagina without symptoms, so treatment should be based on both symptoms and laboratory findings 4
• Recurrent vulvovaginal candidiasis (≥4 episodes/year) requires a different management approach with maintenance therapy 4
• In patients with HIV infection, VVC may be more severe but treatment measures are identical to those for women without HIV 1

Common Pitfalls

• Treating based solely on symptoms without confirmation can lead to inappropriate management 4, 5
• Failure to consider non-infectious causes of vulvar itching 7, 8
• Not recognizing that VVC can present with varying symptom patterns, including itching alone 2, 5
• Assuming that vaginal discharge must be present for diagnosis of VVC 5

By understanding that vulvar itching can be the sole presenting symptom of vaginal yeast infection, healthcare providers can make appropriate diagnostic and treatment decisions while avoiding unnecessary or ineffective therapies.
