Abstract
BACKGROUND: Plasmacytoma of the bladder is an extremely rare tumor, with all information concerning this neoplasm derived from case reports. It can be a major diagnostic pitfall on both histology and urine cytology. CASE: A 95-year-old woman presented with gross hematuria and a large bladder mass detected by ultrasound. The case was initially misdiagnosed as a high grade urothelial carcinoma. Since the urine cytology did not show the classical cytologic features of urothelial carcinoma, the histologic sections were reviewed and immunohistochemical staining performed. The final diagnosis was plasmacytoma of the bladder. Subsequently the patient underwent a skeletal survey and bone scan, which did not reveal any lesion suspicious for multiple myeloma. The patient was scheduled for radiotherapy. CONCLUSION: In this case of bladder plasmacytoma, urine cytology provided a clue to the diagnosis. Urine cytology can be a diagnostic tool to help make this diagnosis in the case of poorly differentiated bladder neoplasm, especially in a patient with a known history of multiple myeloma.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
