What are the recommendations for a repeat Pap test in a patient with atypical squamous cells and a history of fungal infections?

Management of Atypical Squamous Cells with Fungal Infections on Pap Test

Women with atypical squamous cells (ASC-US) and fungal infections should have a repeat Pap test in 4-6 months after appropriate treatment of the infection, preferably after 2-3 months. 1

Understanding Atypical Squamous Cells and Fungal Infections

Atypical squamous cells of undetermined significance (ASC-US) represent a cytologic finding that may be associated with various conditions including:

• Human papillomavirus (HPV) infection
• Reactive changes due to inflammation
• Fungal infections
• Neoplastic processes

Management Algorithm for ASC-US with Fungal Infection

1. Initial Assessment:

   • Evaluate for specific fungal infection (most commonly Candida species)
   • Treat the identified fungal infection with appropriate antifungal therapy

2. Follow-up Protocol:

   • Repeat Pap test after treatment of the infection, preferably after 2-3 months 1
   • If fungal infection persists, continue treatment and reassess

3. Subsequent Management Based on Repeat Pap Results:

   • If normal: Continue routine screening
   • If ASC-US persists:
     • Consider colposcopy if this is a second report of ASC-US within a 2-year period 1
     • Consider HPV testing if available
   • If progression to LSIL or HSIL: Proceed to colposcopy and directed biopsy 1

Special Considerations

Risk Factors for Progression

Certain factors increase the risk of progression from ASC-US to higher-grade lesions:

• History of HPV infection 2
• Smoking 2
• Multiple sexual partners (3 or more) 3
• Lower socioeconomic status 3

Inflammatory Changes vs. Neoplastic Process

When ASC-US is associated with severe inflammation (as often seen with fungal infections):

• The presence of infectious organisms should not influence the diagnosis of ASC-US 4
• However, treating the infection may resolve reactive cellular changes
• Approximately 15.9% of women with ASC-US may have underlying dysplasia 2

Important Caveats

• Do not delay evaluation: While treating the fungal infection is important, it should not significantly delay follow-up of the abnormal cytology
• Age considerations: Women under 40 years with ASC-H (cannot exclude HSIL) have a higher likelihood of having HSIL on biopsy (65.1%) compared to those over 40 (47.5%) 5
• Avoid common pitfall: Do not assume that the presence of a fungal infection explains away the atypical cells - they may coexist with significant pathology

HIV-Positive Patients

For HIV-infected women with ASC-US, management is more aggressive:

• Immediate colposcopy and directed biopsy is recommended 1
• More frequent Pap tests are needed (every 6 months in the first year after HIV diagnosis, then annually if normal) 1

Remember that the goal of appropriate follow-up is to prevent progression to cervical intraepithelial neoplasia and ultimately invasive cervical cancer by identifying and treating precancerous lesions early.
