A 35-year-old woman from rural India presents with postcoital bleeding and vaginal discharge for 3 months. On examination, a friable cervical lesion is noted. Pap smear shows atypical squamous cells of undetermined significance (ASCUS). What is the most appropriate next investigation?

Explanation

## Investigation of Choice: Visible Cervical Lesion with ASCUS **Key Point:** When a clinically visible, friable cervical lesion is present on examination, **colposcopy with directed biopsy** is the most appropriate next investigation — regardless of the cytology result. A visible lesion represents a clinical indication for colposcopy that supersedes cytology-based triage algorithms. ### Why Colposcopy with Directed Biopsy? **High-Yield:** The presence of a friable cervical lesion in a symptomatic patient (postcoital bleeding + vaginal discharge for 3 months) raises strong clinical suspicion for cervical intraepithelial neoplasia (CIN) or invasive carcinoma. In this setting: - A **visible lesion** is an independent indication for colposcopy, irrespective of cytology grade. - ASCUS cytology in the context of a visible lesion does **not** downgrade the clinical urgency — the lesion itself must be histologically characterized. - Colposcopy allows directed biopsy of the most abnormal-appearing area, providing definitive histological diagnosis. Per **ACOG, ASCCP 2019 guidelines** and **ICMR/NCCRT Indian guidelines**, any clinically suspicious cervical lesion warrants colposcopy and biopsy as the primary investigation. Cytology-based triage (HPV reflex testing, repeat Pap) is reserved for asymptomatic women with incidental cytological abnormalities and no visible lesion. ### Why Not Other Options? - **Repeat Pap smear in 12 months:** Unacceptably delayed in a symptomatic patient with a visible lesion; risks missing invasive cancer. - **HPV reflex testing:** Appropriate triage for ASCUS in asymptomatic women with no visible lesion; NOT appropriate when a clinically suspicious lesion is already present — it would only delay definitive evaluation. - **LEEP:** A therapeutic/excisional procedure; cannot be performed without prior histological confirmation of CIN or malignancy. **Clinical Pearl:** The ASCUS cytology result in this case is likely an underestimate of the true pathology (sampling error or observer variability). A friable cervical lesion with postcoital bleeding in a 35-year-old Indian woman must be biopsied promptly — cervical cancer is the second most common cancer in Indian women (Park's Textbook of Preventive and Social Medicine). ### Summary Table | Finding | Next Step | |---|---| | ASCUS, no visible lesion | HPV reflex testing | | ASCUS + visible/friable lesion | Colposcopy + directed biopsy | | HSIL (any) | Colposcopy + directed biopsy | **Reference:** ASCCP 2019 Risk-Based Management Guidelines; ICMR National Cancer Control Programme; Park's Textbook of Preventive and Social Medicine, 26th ed.
