Primary Vaginal Carcinoma Arising on Cystocele Mimicking Vulvar Cancer.

Background: Primary vaginal carcinoma is a rare gynaecological tumour representing 1%-3% of all gynaecologic cancers. Several studies report increased vaginal cancer risk associated with genital prolapse following the occurrence of inflammatory lesions or decubitus ulcers.

Case: We report the rare case of an 82-year-old woman with primary squamous cell carcinoma arising from vaginal wall prolapse. Vaginal carcinoma was suspected during gynaecological examination for vulvar bleeding. A wide local excision was performed and pathologic examination revealed a primary squamous cell carcinoma of the vagina.

Conclusion: Persistent genital prolapse may be at risk for vaginal carcinoma, and cytological and a colposcopic assessments are essential to identify patients who require diagnostic biopsy.
