Cutaneous Metastases From Transitional Cell Carcinoma of the Renal Pelvis: A Case Report
Bibliographic record
Abstract
A 73-year-old female patient presented with left back pain. Computed tomography showed a mass around the left renal hilum and subcutaneous masses in her abdomen. She was referred to our hospital. Retrograde pyelography showed an upper urinary tract obstruction. Urinary cytology of the ureter was negative. Biopsy of the subcutaneous mass was performed, and the pathological findings showed transitional cell carcinoma. She was diagnosed with transitional cell carcinoma of the left renal pelvis with metastasis to the skin (cT4N0M1). She received combination chemotherapy, but the size of her skin lesions was increasing. Three months after admission, she died. Metastasis to the skin from the renal pelvis is very rare; only four cases have been reported. Our case is the first report on transitional cell carcinoma of the renal pelvic metastasizing to only the skin at presentation. We herein summarize this rare metastasis and discuss its clinical features and therapeutic management. doi: http://dx.doi.org/10.4021/wjnu45w

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.
