Abstract:
A rare case of a carcinoma in situ arising from an endocervical polyp is described. The covering epithelium of the polyp transformed gradually into a carcinoma in situ via squamous metaplasia and dysplasia, spreading horizontally with glandular involvement, and colliding with the surface columnar cells. The lack of tumor tissue in the pedicle and adjacent cervical region confirms the case was a carcinoma in situ originating from the surface epithelium of the endocervical polyp.
