Disease Profile

Adenosarcoma of the uterus

Prevalence
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance

Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.

no.svg

Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.

X-linked
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.

X-linked
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.

Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.

Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Summary

Adenosarcoma of the uterus is a rare tumor of the uterus that typically originates in the lining of the uterus (endometrium).[1] This type of tumor is characterized by both benign (noncancerous) and malignant components (low-grade sarcoma).[1][2] Typical symptoms in affected individuals may include abnormal vaginal bleeding, an enlarged uterus, and tissue protruding from the external os (external opening of the uterus that leads into the cavity of the cervix).[1][3] It is most common in post-menopausal women but can affect women of any age.[3] Factors that may predisposed an individual to the condition include hyperestrogenemia (high blood estrogen levels), chemotherapy, or radiotherapy.[3] Recommended treatment includes hysterectomy, usually accompanied by bilateral salpingo-oophorectomy (removal of fallopian tubes and ovaries).[1] Ovarian conservation is an option for reproductive age women.[1]

Cause

The exact cause of adenosarcoma of the uterus is not always known. The development of these tumors has been associated with a few risk factors. Risk factors are associated with an increased risk of developing a condition; however, most people with these risk factors will never develop the condition. Factors that have reportedly been associated with development of adenosarcoma of the uterus include hyperestrinism (abnormally high levels of estrogenic hormones in the body), prior chemotherapy, prior radiotherapy and tamoxifen therapy (used as an adjuvant drug for breast cancer).[3][4][5]

Organizations

Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer. Inclusion on this list is not an endorsement by GARD.
