Benign Endocervical Polyp with Heterologous Elements in a 42-year-old Female: Report of a Case

A 42-year-old female with unremarkable medical history presented for a routine cervical screening upon which an endocervical polyp was identified and submitted entirely for histopathologic evaluation. Microscopic examination showed multiple well-circumscribed nodular fragments of polyp with superficial erosion and focal acute inflammation. Benign endocervical glands were seen within a fibrotic stroma with a prominent smooth muscle component. Intermixed mature adipose tissue and large thick-walled vessels were also identified. Stromal and epithelial atypia were absent; similarly, stromal cellularity, mitoses, and condensation were not identified. Additional deeper levels did not reveal other heterologous elements. The diagnosis of a benign choristomatous endocervical polyp was rendered. As anticipated, the patient recovered completely. A review of the English literature demonstrates rare, namely two other reports of hamartomatous tissue in an endocervical polyp. To the best of our knowledge, we report the third such case.
