Ovarian Clear Cell Carcinoma Presenting as Non-bacterial Thrombotic Endocarditis and Systemic Embolization
Bibliographic record
Abstract
Non-bacterial thrombotic endocarditis (NBTE) is a rare manifestation of cancer-induced hypercoaguability. It most commonly occurs in association with mucin-producing adenocarcinomas and has rarely been described with ovarian clear cell carcinoma (OCCC). We report a case of NBTE with multi-organ embolic infarcts occurring in a patient with early stage clear cell ovarian cancer. A 56 years old Caucasian female presented with leg pain, and left flank discomfort. Evaluation revealed multi-organ infarction, extensive deep vein thrombosis (DVT), and the incidental presence of an asymptomatic large ovarian mass with a laboratory picture consistent with disseminated intravascular coagulation (DIC). The diagnosis of NBTE was supported by echocardiogram and multiple negative bacteriological studies. She underwent surgical extirpation of an early stage OCCC and initiation of anticoagulation. Postoperatively, the patient's hypercoaguability promptly resolved with gradual resolution of vegetations. Subsequent recurrence of the malignancy was heralded by a return of the prothrombotic state. This case shows a rarely reported association between NBTE and OCCC. It illustrates how the clinical picture of NBTE can dominate the initial presentation of an early stage and otherwise asymptomatic malignancy. Late recognition can lead to significant morbidity and a rapidly fatal course. Recurrent thromboembolism may be the first indication of disease recurrence.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
