Cervical Deciduosis in Early Pregnancy Mimicking Malignancy: A report of two cases

Deciduosis is a benign condition characterised by the transformation of subepithelial connective tissue into decidual-like cells, typically occurring in response to hormonal changes during pregnancy. Although benign, cervical deciduosis may macroscopically resemble malignant lesions, leading to diagnostic uncertainty. This report presents two cases of cervical deciduosis diagnosed in early pregnancy. Both patients presented with first-trimester vaginal bleeding, and speculum examination revealed extensive wart-like lesions covering the cervix. Histopathological examination of cervical biopsies confirmed decidual changes. In pregnant women presenting with threatened miscarriage, a thorough local examination and biopsy of atypical cervical lesions are essential to exclude malignancy. As cervical deciduosis is a benign and self-limiting condition, no further treatment is usually required.
