Extrarenal rhabdoid tumor of anterior mediastinal location
Bibliographic record
Abstract
BACKGROUND: Rhabdoid tumors are malignant neoplasms of low prevalence, aggressive behavior, and high mortality. They were initially described as renal tumors, although tumors with the same histopathological and immunohistochemical characteristics have been discovered in other locations, mainly in the central nervous system. Few cases of mediastinal location have been reported internationally. This work aimed to describe the case of a mediastinal rhabdoid tumor. CASE REPORT: We describe the case of an 8-month-old male patient admitted to the pediatric department with dysphonia and laryngeal stridor progressing to severe respiratory distress. Contrast-enhanced computed tomography of the thorax showed a large mass with homogeneous soft tissue density, and smooth and well-defined borders, with suspicion of malignant neoplasm. Due to the oncological emergency compressing the airway, empirical chemotherapy was initiated. Subsequently, the patient underwent incomplete tumor resection due to its invasive nature. The pathology report showed morphology compatible with a rhabdoid tumor, which immunohistochemical and genetic studies corroborated. Chemotherapy and radiotherapy to the mediastinum were administered. However, the patient died three months after the initial treatment due to the aggressive behavior of the tumor. CONCLUSIONS: Rhabdoid tumors are aggressive and malignant entities difficult to control and have poor survival. Early diagnosis and aggressive treatment are required, although the 5-year survival does not exceed 40%. It is necessary to analyze and report more similar cases to establish specific treatment guidelines.

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.
