Background: Cervical polyps (CP) are quite common in adults, they are extremely rare in children and adolescents. CP containing mesonephric duct remnants (MDR) are few millimeters in size and seldom grossly visible.
Case: A 14-year-old female admitted with massive vaginal bleeding with an intact wide hymeneal opening. Pelvic MRI revealed 47 mm × 25 mm × 35 mm polypoid mass originating from the endometrial cavity. During vaginoscopy, a polypoid mass was detected at 9 o'clock position of right lip of ectocervix and was totally excised. Light microscopy showed CP including small round or branched glands containing inspissated eosinophilic secretions and patchy chronic inflammatory infiltrate. The patient was diagnosed as gaint CP containing MDR.
Conclusion: Giant CP is an uncommon variant of classical polyps and exhibit distinct clinical and pathologic features. However, MDR are benign lesions of cervix, detailed histopathological evaluation should be performed to all CP to differentiate malignant lesions.
