Cervical deciduosis imitating dysplasia

Abstract

Ectopic cervical deciduosis is generally an accidental finding during pregnancy, and usually presents without any symptoms or need for therapeutic intervention. However, it can sometimes imitate dysplasia or carcinoma. We report a case of a 34-year-old G2P0, with a history of cervical dysplasia, presenting at 11 weeks of gestation, with vaginal blood loss. During examination, lesions mimicking dysplasia were found on the cervix. Histological examination reported cervical deciduosis. Deciduosis is a benign change during pregnancy and will resolve spontaneously. With the increasing use of cytology and colposcopy, the reported incidence is growing. When it is hard to differentiate between dysplasia and deciduosis, histological confirmation should be considered.

A rare case of symptomatic recurrent decidual polyp in each pregnancy in a woman with primary infertility

“…Most of them are diagnosed in the first trimester (most commonly between the 5th and the 12th week of gestation) and start to regress after the 25th week. All decidual changes regress in the period between the 38th week of pregnancy [2] and 4-6 weeks after delivery [1].…”

“…During pregnancy, the endometrium undergoes a physiological decidual transformation as a result of elevated progesterone levels and its consequently potentiated action [1]. However, decidual foci sometimes can be found in other parts of the female reproductive system (vagina, cervix, fallopian tubes, ovaries), rarely even in the abdominal cavity [2].…”

“…However, decidual foci sometimes can be found in other parts of the female reproductive system (vagina, cervix, fallopian tubes, ovaries), rarely even in the abdominal cavity [2]. In those cases, it is called ectopic decidua or deciduosis [1].…”

“…The first one suggests that cervical stroma cells undergo decidual metaplasia as a result of inflammation, which makes them more susceptible to stimulation by hormones (predominantly progesterone) and other signal molecules, elevated during pregnancy. The other explanation proposes the presence of endometrial foci within the cervix, which undergoes the same changes as normal endometrial tissue during pregnancy [1,2].…”

Cervical deciduosis: precarious mimicker of malignancy during pregnancy

“…At times, it can be exuberant, requiring histopathologic examination. During labor, it can lead to massive necrosis, antepartum hemorrhage, and complications relating to it 3. Deciduosis regresses within 4–6 weeks of childbirth and needs symptomatic management.…”
