Angiosarcoma of the Thyroid Gland: A Case Report
Bibliographic record
Abstract
The authors described a case of rare histological type of primary thyroid tumour: angiosarcoma. We report a case of 37 years old female who presented with the mass in the anterior of the neck that had been rapidly growing for several months. Scintigraphy showed a cold nodule in the left lobe of the thyroid. The patient underwent subtotal thyroidectomy. The cut surface showed a bulging solid grey hemorrhagic mass, measuring 6.5 cm at the lower pole of the left lobe. Microscopically a poorly differentiated highly desmoplastic polymorphocellular tumour. Immunohistochemically, the cells showed immunoreactivity for endothelial markers CD31, CD34, Facor VIII related antigen and immunonegativity for epithelial markers including pancytokeratin, epithelial membrane antigen and thyroglobulin. Radiotherapy was applied. The patient was alive after a follow up of five months. doi:10.4021/jmc2010.07.107e

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.
