Strawberry cervix is caused by
**Core Concept**
The strawberry cervix is a clinical sign characterized by a cervical appearance resembling a strawberry due to the presence of punctate hemorrhages on the surface. This condition is often associated with cervical neoplasia, particularly cervical carcinoma.
**Why the Correct Answer is Right**
The strawberry cervix is caused by submucosal hemorrhages and neovascularization, which are hallmarks of cervical cancer. The increased vascularity and subsequent bleeding are thought to be mediated by vascular endothelial growth factor (VEGF) and other angiogenic factors produced by the tumor. The punctate hemorrhages give the cervix a characteristic strawberry-like appearance.
**Why Each Wrong Option is Incorrect**
**Option A:** Intraepithelial neoplasia is a precancerous condition that does not typically present with the strawberry cervix appearance.
**Option B:** Cervical ectropion refers to the presence of columnar epithelium on the ectocervix, which is a normal variant and does not cause a strawberry cervix.
**Option C:** Cervical polyps are benign growths that can cause bleeding but do not typically present with a strawberry cervix appearance.
**Clinical Pearl / High-Yield Fact**
The strawberry cervix is a clinical sign that warrants further investigation, including colposcopy and biopsy, to rule out cervical carcinoma.
**Correct Answer:** C. Cervical carcinoma.
