Multifocal Ancient Thoracic Schwannomas: A Case Report and Review of Literature
Bibliographic record
Abstract
Primary pleural schwannoma is a rare benign tumor of the thorax. Because of their gradual progression, they are generally asymptomatic. Herein, we report a 53-year-old male patient with a well-circumscribed mass located at the right lower lung field. He was totally asymptomatic. His contrast-enhanced computerized tomography scan showed a round, well-defined, inhomogeneous, mildly-enhancing lesion with a few small internal speckle calcifications arising from the pleura along the right lateral sixth intercostal space, measuring about 5.5 × 4.2 cm in diameter, and another smaller lesion at the left apical hemithorax. Both masses were resected successfully under video-assisted thoracoscopic surgery. Histopathologic analysis revealed alternating areas of compact spindle cells and hypocellular areas and degenerative changes of blood vessels inside. Thus, the diagnosis of multifocal ancient thoracic schwannomas was established. J Med Cases. 2017;8(9):277-279 doi: https://doi.org/10.14740/jmc2888w

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.
