Fine Needle Aspiration Biopsy of Anaplastic Thyroid Carcinoma Developing from a Hürthle Cell Tumor
Bibliographic record
Abstract
BACKGROUND: Anaplastic thyroid carcinoma is a highly malignant tumor in elderly people with a long history of multinodular goiter and is usually associated with a rapidly fatal clinical evolution. The tumor often develops as a result of anaplastic transformation of a slowly growing papillary carcinoma or follicular neoplasm. CASE: An 85-year-old woman had a multinodular goiter and had been asymptomatic, with a normal white blood cell count and chest radiograph three months prior to her hospital admission for the treatment. The tumor presented with low grade fever, leukocytosis, multiple metastatic lung nodules and enlargement of the intrathoracic thyroid in a period of three months, causing compression of the esophagus and trachea. Despite a total thyroidectomy, the tumor recurred within one month and caused dysphagia and death. CONCLUSION: FNAB permitted the diagnosis of an anaplastic thyroid carcinoma arising from an intrathoracic Hürthle cell tumor.

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.
