Microcystic stromal tumor

Microcystic stromal tumor is a very rare type of benign (non-cancerous) tumor that grows in the ovary. It belongs to a group called sex cord-stromal tumors, which develop from the supporting tissue of the ovary rather than from egg cells. These tumors are sometimes called microcystic stromal tumors of the ovary (MCST). They are almost always found in just one ovary and do not typically spread to other parts of the body, which makes them different from many other ovarian tumors. Most women with this tumor do not have obvious symptoms at first. When symptoms do appear, they are usually caused by the growing mass pressing on nearby organs. Common signs include pelvic pain or pressure, a feeling of fullness in the abdomen, and sometimes an abnormal lump that can be felt or seen on imaging. Some tumors are found by accident during a scan done for another reason. The main treatment is surgery to remove the tumor, which is usually curative. Because these tumors are so rare, there is limited long-term data, but the outlook after surgery is generally very good. Research has found that many of these tumors are linked to changes in a gene called CTNNB1, which is important for cell growth control. Ongoing research is helping doctors better understand this condition and how to manage it.
