The condition in five sentences. Uterine adenosarcoma is a rare biphasic Müllerian tumour with benign-appearing epithelium and a malignant stromal component, originally described in 1974; it can be mistaken preoperatively for a polyp or fibroid (Clement 1974, PMID 4371193; Clement 1990, PMID 2156771). Recurrence estimates are case-mix dependent: a narrative review states “at least 50%,” whereas Clement’s primary 100-case series reported 23 recurrences and Carroll’s stage I cohort reported 77% with sarcomatous overgrowth versus 22% without (Nathenson 2018, PMID 30169984; Clement 1990, PMID 2156771; Carroll 2014, PMID 25449308). Sarcomatous overgrowth has consistent multivariable support — in Carroll’s 74-patient single-institution cohort it separated median PFS of 29.4 from 105.9 months (HR 2.58, 95% CI 1.37–4.84) and OS of 55.4 from 112.4 months (HR 2.45, 95% CI 1.26–4.76) (PMID 25449308). Outside single institutions the evidence is registry-based and lacks central pathology review: NCDB counted adenosarcoma as 0.43% of uterine cancers; a SEER analysis of 544 adenosarcomas found stage I 5-year survival 79% (95% CI 75–84%) versus 48% (95% CI 29–65%) for stage III, and a 797-patient SEER model reached c-index 0.774 without measuring overgrowth (Seagle 2016, PMID 27771166; Arend 2010, PMID 20688363; Qu 2020, PMID 33680946). The safety problem is preoperative misidentification—occult uterine sarcoma occurred in 1 per 278 presumed-leiomyoma hysterectomies in a 34,728-procedure cohort, although that denominator is not adenosarcoma-specific—and the trial gap is no adenosarcoma-only randomised study or reported histology-specific randomised result (Raine-Bennett 2016, PMID 26646120).

The scoping decision that shapes this condition¶
A PubMed search for uterine adenosarcoma returns 258 records in total (re-checked 2026-09-01). Most of what exists is case reports and single-institution retrospective series. The largest multivariable institutional cohorts cited here are 74 (Carroll) and 165 (Nathenson); the largest cited dataset is 2,205 NCDB records without central pathology review.
Two consequences, both deliberate:
The page list is 14, not the usual 19–20. Topics that earn a page in a common condition would be empty here.
The density target does not apply. See .density-exempt. Fourteen pages at 24 citations would need 336 citation-slots from a 258-record literature. A future deepen pass must not inflate it. Every claim is sourced and the grade of each source is visible on the page.
Seed-anchor corrections made at build. PMID 29441675 is Tate et al., not Tanaka. PMID 26646120 is Raine-Bennett et al., not Multinu; the Multinu occult-sarcoma paper is PMID 30447212 (2019).
Reading paths¶
- Clinical path — overview → pathology and diagnosis → sarcomatous overgrowth → staging and prognostic factors → surgical management → adjuvant and systemic therapy → guidelines
- Science path — pathology and diagnosis → sarcomatous overgrowth → molecular and genomic features → epidemiology and burden
- "What's unknown" path — OPEN-QUESTIONS.md → clinical-trials landscape → guidelines
- Safety / human path — red flags and safety concerns → clinical presentation and imaging → patient experience and advocacy → recurrence and surveillance
