Retroperitoneal Inflammatory Myofibroblastic Tumor: Case Report and Immunohistochemistry Study
Bibliographic record
Abstract
Inflammatory myofibroblastic tumors (IMT) are a rare clinicopathological entity of yet unknown etiology and those located retroperitoneally are even rarer. Clinical outcome is unpredictable and complete surgical resection of the tumor remains the principal treatment. We report the case of a 41-year old man presented with abdominal pain. An abdominal magnetic resonance imaging scan revealed a retroperitoneal tumor located between the pancreas, stomach small curvature and big vessels. A laparotomy with biopsy was performed because the tumor was not amenable to surgical resection. Histopathological examination concluded to an IMT with overexpression of protein p53. Epstein-Barr virus and Human Herpesvirus-8 investigation was negative. Postoperative outcome was unfavorable.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
