Extreme Rare Case of Primary Signet Ring Cell Carcinoma of Gall Bladder-Case Report
Bibliographic record
Abstract
Primary carcinoma of the gallbladder is an uncommon malignancy with a variable incidence. Women are affected generally than men (3-4:1) with higher incidence in increasing age. The signet ring cell sub type of adenocarcinoma is a rare and aggressive variant carrying worse prognosis. We report a case of primary signet ring cell carcinoma of gallbladder in a 55yr old woman. Ultrasound showed thickened gallbladder with multiple gallstones. Patient underwent open cholecystectomy. Grossly gallbladder was thickened with multiple stones. Histopathological examination revealed sheets of signet ring cells infiltrating full thickness of the wall. H&E, periodic acid–Schiff (PAS), Alcian blue & Cytokeratin 7 stains confirmed presence of signet ring cells. Post-op Endoscopy with biopsy was done to rule out primary in stomach. Early diagnosis and new lines of treatment in chemotherapy or new biological therapy should be encouraged to improve the survival and life quality.

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.
