Overview

Seromucinous cystadenoma of childhood is a rare, non-cancerous (benign) tumor that grows on or near the ovary. It belongs to a group of cysts called seromucinous tumors, which are lined by cells that produce a watery or mucus-like fluid. These tumors are unusual in children and teenagers, making them especially rare compared to similar growths seen in adult women. The tumor is sometimes called a mixed epithelial cystadenoma or seromucinous ovarian cyst. Most children with this condition develop a painless or mildly uncomfortable swelling in the lower belly. Because the tumor grows slowly and is benign, it does not spread to other parts of the body. However, it can grow large enough to cause pressure, bloating, or pain in the abdomen. In some cases, the cyst can twist (a complication called ovarian torsion), which is a medical emergency requiring urgent surgery. The main treatment is surgical removal of the cyst, and most children recover fully after the operation. Doctors try to preserve the ovary whenever possible to protect future fertility. Long-term outlook is generally excellent, and the tumor rarely comes back after complete removal. Regular follow-up with imaging is recommended to make sure the tumor does not return.
