Deciduoma

Deciduoma is a collection of tissue in the uterus formed by remnants of the decidua. The decidua is a layer of the uterine mucosa modified under the influence of progesterone, into which a fertilized egg is implanted.

Deciduoma can occur after pregnancy, miscarriage, or medical abortion because not all of the decidua tissue is shed. More often, deciduoma is benign and does not require treatment, less often it is malignant (chorionepithelioma).

For differential diagnosis of deciduoma and chorionepithelioma, a histological examination is performed. Treatment for malignant deciduoma includes surgical removal and/or chemotherapy.



A deciduoma is a collection of tissue that forms in the uterus after childbirth. These are the remains of the decidua that covers the fetus during pregnancy. The decidua is essential to protect the fetus from infections and other threats.

However, if the decidua remains in the uterus for too long, it can lead to the formation of a deciduoma. Deciduoma can be either benign or malignant.

A benign deciduoma usually does not cause any symptoms and can only be detected during a pelvic examination. However, if a deciduoma becomes cancerous, it can cause symptoms such as abdominal pain, bleeding, anemia, and others.

To prevent the formation of deciduoma, you need to monitor your health and undergo regular gynecological examinations. It is also important to ensure that the decidua is completely separated from the fetus after birth.
