[Morphologic changes in cervix smears by intrauterine pessary]

Area of Science:

• Gynecologic pathology
• Cervical cytology
• Reproductive health

Context:

• Intrauterine devices (IUDs) are widely used for contraception.
• Cervical cytology, including Pap smears, is crucial for detecting precancerous and cancerous changes.
• Morphological changes in cervical cells associated with IUD use require characterization.

Purpose:

• To investigate morphological alterations in cervical smears and endocervical biopsies from women using intrauterine devices (IUDs).
• To compare the incidence of cellular changes in IUD users versus a control group.
• To determine if IUD duration impacts cellular alterations.

Summary:

• Slight to moderate cellular alterations were observed in 31% of cervical smears and 35% of endocervical biopsies from IUD users.
• Inflammatory and metaplastic changes were more frequent in IUD users compared to controls.
• No increased incidence of dysplastic lesions was found in IUD users; "Actinomyces-like" organisms were noted in 6% of cases.
• IUD duration did not correlate with the observed cellular alterations.

Impact:

• Cytopathologists can identify potential IUD-related changes in approximately one-third of Pap smears from IUD users.
• This study highlights characteristic cellular alterations that may be mistaken for dysplasia, emphasizing the need for clinical history.
• Understanding these benign changes improves diagnostic accuracy and patient management in women using IUDs.
