Giant endocervical polyp mimicking cervical malignancy: primary excision and hysteroscopic resection.

Giant cervical polyps are characterized by an unusually large size and appear clinically as malignant. A 35-year-old woman had increased vaginal discharge and lower abdominal discomfort. At examination, a fist-sized, hard, consistent mass was found in the vagina. Pelvic magnetic resonance imaging revealed a 12.6 x 8-cm solid tumor with internal papillary growth within the entire vaginal cavity. The tumor base was suspected to have originated from the endocervix by a connecting stalk. Primary excision of the tumor was performed via the vagina, and the remnant tissue was completely removed at hysteroscopic resection. The final histopathologic findings confirmed a benign giant cervical polyp.
