A Rare Case of Primary Angiosarcoma of Ovary in a Postmenopausal Woman
Bibliographic record
Abstract
Primary angiosarcoma of the ovary is a rare and aggressive subset accounting for less than 1% of ovarian malignancies. We present a rare case of primary angiosarcoma of the ovary in a 52-year-old healthy postmenopausal woman who presented with mild abdominal pain, distension and poor appetite of 1 week duration. On abdominal examination, right iliac fossa fullness with shifting dullness was noted. A CT of abdomen and pelvis revealed a right 10.5 cm complex solid cystic mass with ascites and peritoneal nodularity. Her CA125 was 560 U/mL. She subsequently underwent full surgical staging and optimal debulking surgery. Final histology confirmed angiosarcoma of ovary grade 3 FIGO stage IIA ovarian cancer. A repeat CT of abdomen and pelvis done 4 weeks later prior to starting chemotherapy showed large 6.5 × 6 cm pelvic peritoneal deposits with cystic septation and solid components. Her disease progressed despite palliative chemotherapy and she unfortunately passed away several months after surgery. We reiterate that primary angiosarcoma of the ovary is an aggressive tumor with poor prognosis despite optimal surgical treatment.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
