title: Endocervical Polyp With Florid "Epidermal Metaplasia": Report of a Previously Undescribed Phenomenon.
abstract: Endocervical polyps are common benign lesions which rarely result in diagnostic problems, although a variety of alterations occasionally complicate histologic interpretation. We report an unusual, and not previously described, finding of florid "epidermal" metaplasia with keratinization and extensive formation of skin appendages structures (sebaceous and sweat glands and hair follicles) within an endocervical polyp. The features closely resembled an epidermal inclusion cyst. We speculate on the possible pathogenesis of this rare phenomenon and review unusual findings in endocervical polyps.
