What is Ovarian fibrothecoma?
Ovarian fibrothecoma is a rare, usually benign (non-cancerous) tumor that grows in the ovary. It belongs to a group of tumors called sex cord-stromal tumors, which develop from the connective tissue cells that support the ovary and produce hormones. The name "fibrothecoma" reflects that the tumor contains a mix of two cell types: fibroma cells (which make fibrous tissue) and thecoma cells (which can produce hormones like estrogen). These tumors are sometimes also called ovarian fibroma-thecoma or simply fibrothecoma. Many women with ovarian fibrothecoma have no symptoms at all, and the tumor is found by chance during imaging or surgery for another reason. When symptoms do occur, they may include pelvic pain or pressure, a feeling of fullness in the abdomen, abnormal vaginal bleeding, or bloating. In some cases, the tumor produces excess estrogen, which can cause irregular periods, postmenopausal bleeding, or thickening of the uterine lining (endometrial hyperplasia). A rare but notable complication is Meigs syndrome, where the tumor causes fluid to build up in the abdomen (ascites) and around the lungs (pleural effusion). The main treatment for ovarian fibrothecoma is surgery to remove the tumor. In younger women who wish to preserve fertility, only the affected ovary may be removed. In older or postmenopausal women, removal of both ovaries and the uterus may be recommended. Because these tumors are almost always benign, the outlook after surgery is generally excellent, and recurrence is very rare.

How is Ovarian fibrothecoma inherited?
Ovarian fibrothecoma follows a sporadic inheritance pattern. Genetic counseling can help families understand recurrence risk and testing options.
At what age does Ovarian fibrothecoma typically begin?
Typical onset of Ovarian fibrothecoma is adult. Age of onset can vary across affected individuals.
Frequently asked questions about Ovarian fibrothecoma
Auto-generated from canonical disease facts (Orphanet, OMIM, ClinicalTrials.gov, openFDA, NPPES). Not a substitute for clinical guidance.
What is Ovarian fibrothecoma?
Ovarian fibrothecoma is a rare disease catalogued in international rare-disease ontologies (Orphanet ORPHA:314478). It is typically inherited as sporadic. Age of onset is generally adult. For verified primary sources, see the UniteRare Ovarian fibrothecoma page.
How is Ovarian fibrothecoma inherited?
Ovarian fibrothecoma follows sporadic inheritance. Genetic counseling is recommended for affected families to understand recurrence risk in offspring and the likelihood of unaffected siblings being carriers. Variants in the underlying gene(s) may be identified via clinical genetic testing.
Are there FDA-approved treatments for Ovarian fibrothecoma?
Approved treatments for Ovarian fibrothecoma are tracked from openFDA and DailyMed primary sources. Many rare diseases have no specific FDA-approved therapy; for those, supportive care and management of complications form the basis of clinical care. Orphan-drug-designation status is noted where applicable.
Are there clinical trials for Ovarian fibrothecoma?
Active clinical trials for Ovarian fibrothecoma are tracked daily from ClinicalTrials.gov. Trial availability changes frequently; check the UniteRare trial listings for the current count and recruitment status. Sponsors of rare-disease research often welcome inquiries even when a trial is not actively recruiting at a given moment.
How do I find a specialist for Ovarian fibrothecoma?
Verified Ovarian fibrothecoma specialists are identified through ClinicalTrials.gov principal-investigator records, peer-reviewed publication authorship (via PubMed), and the NPPES NPI registry. NORD-designated Centers of Excellence and NIH-affiliated rare-disease clinics are also tracked. UniteRare's specialist directory is updated continuously as new evidence becomes available.
