Abstract
STUDY DESIGN: A retrospective review of a case of primary leptomeningeal melanoma. OBJECTIVES: To present a previously undescribed tumor of the lumbar meninges. BACKGROUND: The case described the first report of lumbar localization and of bony metastasis of this tumor. METHODS: The authors present a case of a 65-year-old man with a destruction of the fifth lumbar vertebra and an exacerbation of lumbar pain and acute sensorimotor radiculopathy. RESULTS: The histologic examination of the resected tissue after the transpedicular stabilization suggested the presence of metastatic melanoma. After the development of progressive paraplegia and a second operation, subsequent histologic examination of the resected tissue showed the lesion to be a primary leptomeningeal melanoma. The patient's condition deteriorated progressively, and 31 days after confirmation of the diagnosis, he died of meningeal melanomatosis. CONCLUSION: By indicating the possibility of hitherto unreported sites of occurrence, routes of metastatic spread, and manifestations of this malignant tumor, this case report may contribute to the further elucidation of this disease.

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.
