Rare presentation of cervical deciduosis as antepartum haemorrhage

Cervical deciduosis refers to the condition in which ectopic decidual changes take place in the cervix. It is mostly asymptomatic but sometimes may have various clinical presentations. In our case, patient had a rare clinical presentation of cervical deciduosis, in the form of an antepartum haemorrhage at 32 weeks. On examination, there were multiple friable lesions measuring 5-15 mm in size on both the lips of the cervix and it was very much simulating to malignancy, so biopsy was done. However, biopsy led to uncontrolled bleeding and finally the patient required premature lower segment caesarean section. Both mother and baby were well. Biopsy report was diagnostic of cervical deciduosis. On follow-up at 6 weeks post partum, the cervix was found to be absolutely healthy. Since, cervical deciduosis is a benign condition which gets resolved 4-6 weeks post partum. So, keeping differential diagnosis of cervical deciduosis in mind is very important to avoid unnecessary cervical biopsies during pregnancy. And patient with suspicion of cervical deciduosis should be followed up postpartum strictly.
