Management of Irregular Brown-White Cervical Lesion in a 40-Year-Old Woman
Any visible cervical lesion, regardless of appearance or prior screening results, requires immediate direct biopsy to rule out invasive cancer. 1
Immediate Diagnostic Steps
Perform colposcopy-directed biopsy of the visible lesion as the first priority. 1 The irregular brown-white appearance represents a grossly visible abnormality that bypasses routine screening algorithms and mandates tissue diagnosis. 1
Concurrent Procedures During Initial Evaluation
Obtain cervical cytology using the Bethesda System at the time of biopsy, even though cytology has low sensitivity for grossly visible cancers and should never be used to exclude malignancy in the presence of a visible lesion. 1
Perform comprehensive colposcopic examination after applying 3-5% acetic acid solution to map the full extent of the lesion and document whether the entire squamocolumnar junction is visualized (satisfactory vs. unsatisfactory colposcopy). 2, 1
Take multiple colposcopy-directed biopsies (at least two specimens from the worst-appearing areas), as the combined sensitivity of two biopsies for detecting CIN 2+ exceeds 90%. 3
Perform endocervical curettage (ECC) given the patient's age of 40 years, as ECC detects an additional 2.4% of CIN 2+ lesions in women ≥40 years that would be missed by ectocervical biopsies alone. 3, 4 The diagnostic yield of ECC is significantly higher in women ≥40 years compared to younger women (40.7% vs. 19.2%, P<0.001). 5
Management Based on Histopathology Results
If Biopsy Shows Invasive Cancer
Immediate referral to gynecologic oncology is mandatory. 1, 6 Treatment follows cervical cancer staging guidelines with multidisciplinary involvement including surgical oncology and radiation oncology. 2, 6
If Biopsy Shows Adenocarcinoma In Situ (AIS)
Cold-knife conization is the preferred diagnostic procedure because AIS is multifocal and approximately 30% of patients have residual disease despite negative excision margins. 1, 7
For women who have completed childbearing, hysterectomy is the preferred definitive treatment. 1, 7
For fertility preservation, cold-knife conization with concurrent endocervical sampling is required, followed by cytology with or without ECC every 6 months. 1, 7
If Biopsy Shows CIN 2 or CIN 3
Excisional (LEEP or cold-knife conization) or ablative therapy is recommended. 1 However, specific management depends on colposcopy adequacy:
If colposcopy is unsatisfactory (squamocolumnar junction not fully visualized) or if endocervical sampling reveals CIN, a diagnostic excisional procedure is mandatory. 2, 1
If colposcopy is satisfactory, both excision and ablation are acceptable options. 2
Follow-up requires cervical cytology at 4-6 month intervals until 3 consecutive negative results, then annual cytology indefinitely, as recurrent disease can occur many years after treatment. 2, 6
If Biopsy Shows CIN 1
Management depends on the cytology result:
If preceded by ASC-US or LSIL cytology, follow-up with HPV DNA testing annually or repeat cytology every 6-12 months is acceptable, as >90% regress spontaneously within 24 months. 1
If preceded by HSIL or ASC-H cytology, either a diagnostic excisional procedure or observation with colposcopy and cytology every 6 months for one year is acceptable, provided colposcopy is satisfactory and endocervical sampling is negative. 1
Critical Pitfalls to Avoid
Never assume a visible lesion is benign based on normal cytology or negative HPV testing. 1 Cytology has poor sensitivity for grossly visible cancers, and screening test results do not modify the need for immediate biopsy of visible lesions.
Never perform ablative therapy without histologic confirmation of the lesion grade and extent, as this could destroy evidence of invasive cancer. 1
Never rely on negative margins after excision to guarantee complete removal of AIS, as residual disease occurs in approximately 30% of cases. 1, 7
Do not defer colposcopy or biopsy in the presence of a visible cervical lesion, even if recent screening was negative. 1
