Introduction: A cervical polyp is a flexible, friable, pedunculated neoplasm, mostly originating from the endocervical area. It is considered giant when it is >4 cm. Most are benign but they must be removed and subjected to histopathologic examination because they may present malignancy. Clinical Case: A 13-year-old female patient, with no personal pathological personal or familiar history, was referred from another health center due to a 1-year history of a vaginal tumor with apparently no underlying cause. Physical examination showed a red, multilobulated, vaginal tumor of approximately 10 cm long, with mucus around it, foul-smelling, easy bleeding, painful on palpation, protruding from vaginal introitus with a deep pedicle. The patient underwent surgery where the excision of the vaginal tumor extending to the exocervix was performed. Conclusion: In this case, due to the initial clinical characteristics, a malignant pathology (such as rhabdomyosarcoma) may be suspected, thus, complementary imaging and laboratory studies need to be performed, to rule out this diagnosis and offer an adequate and well oriented surgical treatment; a subsequent definitive histopathological study needs to be conducted to confirm that the lesion is compatible with an endocervical polyp, determining the patients prognosis and follow-up requirements.
