Abstract
Angiosarcomas are rare, malignant, endothelial-cell tumors of vascular origin that can arise at any body site. They frequently metastasize to the lung, heralded by dyspnea, hemoptysis, chest pain, pneumothoraces, and diffuse pulmonary hemorrhage. However, in most cases lung metastases are discovered after the diagnosis of a primary angiosarcoma has already been established. Very rarely will an undiagnosed metastatic angiosarcoma present as diffuse pulmonary hemorrhage. We describe the case of a 59-year-old male who presented to hospital with dyspnea and hemoptysis. CT chest revealed rapidly progressing nodular changes and broncho-alveolar lavage returns were progressively bloody. Open lung wedge biopsy ultimately revealed metastatic angiosarcoma and extensive pulmonary hemorrhage. Our case highlights the key clinical, radiological, and pathological features of this rare malignancy that frequently metastasizes to the lung and reminds clinicians to consider it as a cause of hemoptysis and pulmonary hemorrhage.

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 it
