Differential Diagnosis for Yellowish Vaginal Discharge with Pruritis
- Single Most Likely Diagnosis
- Bacterial Vaginosis (BV): This condition is characterized by an imbalance in the normal vaginal flora, leading to an overgrowth of bacteria. It often presents with a thin, yellowish, or grayish discharge and is accompanied by pruritis (itching) and a fishy odor. The symptoms match closely with the presentation of yellowish vaginal discharge and pruritis.
- Other Likely Diagnoses
- Vulvovaginal Candidiasis (VVC): Commonly known as a yeast infection, VVC can cause a thick, white, or yellowish discharge and is often associated with intense pruritis. It's a common condition, especially in women of reproductive age.
- Trichomoniasis: This sexually transmitted infection can cause a greenish-yellow, frothy discharge and is often accompanied by pruritis and irritation of the genital area.
- Atrophic Vaginitis: Although more common in postmenopausal women, atrophic vaginitis can cause a thin, yellowish discharge due to the thinning and drying of the vaginal walls. It's associated with pruritis and discomfort.
- Do Not Miss Diagnoses
- Gonorrhea and Chlamydia: These sexually transmitted infections can cause abnormal vaginal discharge and pruritis. Although they might not always present with yellowish discharge, missing these diagnoses can lead to serious complications, including pelvic inflammatory disease (PID) and infertility.
- Cervical Cancer: While rare, advanced cervical cancer can cause abnormal vaginal discharge, which might be yellowish in color. Pruritis is less common but can occur. Given the potential severity of missing this diagnosis, it's crucial to consider it, especially in women who are not up to date with their cervical cancer screening.
- Rare Diagnoses
- Desquamative Inflammatory Vaginitis (DIV): A rare condition characterized by a purulent, yellowish discharge and significant pruritis. It's often resistant to standard treatments and requires specific diagnosis and management.
- Foreign Body in the Vagina: Although more common in children, a foreign body in the vagina can cause a foul-smelling, yellowish discharge and pruritis due to the resulting infection. This diagnosis should be considered, especially if other causes have been ruled out and symptoms persist.
