We present an endocervical polyp with heterologous elements. Although a few neoplastic cervical lesions with cartilaginous and adipocytic heterologous tissue have been reported, an endocervical polyp with heterologous cartilage and adipose tissue has not been reported before our case. The patient was a 33-year-old woman who presented with abnormal uterine bleeding. On physical examination, there were no remarkable findings other than a cervical polyp protruding into the cervical canal. The polyp was removed. Pathological examination revealed an endocervical polyp with typical epithelial features. The stroma of the polyp contained mature cartilage islands and adipose tissue. There were also many thick-walled vascular structures. Neither stromal periglandular condensation nor atypia was found. Mitotic figures were not observed. Arteriolar structures did not contain internal elastic lamina. In our opinion, these pathological findings are all consistent with a hamartomatous lesion rather than with a true neoplasm.
