Clinical definition (Orphanet)
Undifferentiated carcinoma of the corpus uteri is a rare cancer of corpus uteri presenting as a large, polypoid, intraluminal mass with necrosis, composed of small to intermediate-size, relatively uniform, dyshesive cells displaying no differentiation. It usually presents with dysfunctional bleeding or vaginal discharge and, less often, abdominal pain. Association with Lynch syndrome was reported.

Where this condition sits on an open-data research pipeline — not how close a treatment is, and not medical advice. Empty stages often mean “not in these databases under this Mondo ID,” not “impossible.”

Biology
Genes and phenotypes
Gene–disease validity from GenCC, plus phenotypes and animal models joined from Monarch Initiative via Mondo ID — not a clinical diagnosis aid.
Do we know what causes it?
Not yet — the cause hasn't been pinned down in GenCC.
No strong gene–disease assertion joined for this Orphanet entity.
Phenotypes (Monarch / HPO)
Not enriched in this build — Monarch phenotype joins were not run for this record.

We do not yet link condition-specific patient organisations. These umbrella groups support undiagnosed and ultra-rare families:
India — NPRD
Last verified 2026-07-26This ORPHAcode is not on our curated NPRD list (direct or Mondo-parent match). That does not decide clinical eligibility; families in India should ask a notified Centre of Excellence about current coverage.
Hand-curated for this project. ORPHAcode mappings are best-effort and may be incomplete or imprecise for umbrella categories. Parent (Mondo) matches mean the policy lists a broader category — confirm eligibility with a Centre of Excellence. Financial entitlements summarised from public policy statements and may change. This is not official government guidance.
How we counted this
Europe PMC query (preferred label + any corrected label + Orphanet and Mondo exact synonyms, stoplisted; unioned with resolved MeSH labels when available). UMLS / OMIM / NCIT cross-references are stored on the overview but are not added to the query string.
"Undifferentiated carcinoma of the corpus uteri" OR "Undifferentiated carcinoma of corpus uteri" OR "Endometrial undifferentiated carcinoma" OR "body of uterus undifferentiated carcinoma" OR "body of the uterus undifferentiated carcinoma"
ClinicalTrials.gov query (quoted phrases + MeSH via query.cond, plus recall-expansion terms when used):
"Undifferentiated carcinoma of the corpus uteri" OR "Undifferentiated carcinoma of corpus uteri" OR "Endometrial undifferentiated carcinoma" OR "body of uterus undifferentiated carcinoma" OR "body of the uterus undifferentiated carcinoma"
Interventional trials matched via: phrase (mesh = registered under a MeSH descriptor no name phrase would catch; recall-expansion = gene / selected parent terms used only for trials).
