Carcinoma of the larynx, metastatic to illeum, presents as ruptured appendicitis: Case report and literature review
Bibliographic record
Abstract
OBJECTIVES: Metastasis of laryngeal squamous cell carcinoma (SCC) to the intra-abdominal gastrointestinal tract is exceedingly rare. The objectives of this case report are to describe a case involving a perforated metastasis of a laryngeal SCC to the ileum and to review the literature pertaining to other similar cases. METHODS: A review of patient's chart and a review of the English literature involving malignant SCC of the larynx with metastasis to the small bowel. RESULTS: We describe the case of a 58-year-old man who had failed induction chemotherapy and underwent a laryngopharyngectomy with bilateral neck dissection and pectoralis major flap for a T4N2c laryngeal SCC. Subsequently, the patient was treated with postoperative radiation and cituximab.The patient went on to present with symptoms consistent with a ruptured appendix, supported by ultrasound imaging. The patient was taken to the operating room where a right hemicolectomy was performed. Pathological gross examination confirmed a 4 cm transmural perforation in the terminal ileum. Microscopy demonstrated deposits of metastatic squamous cell carcinoma in the surrounding smooth muscle. Metastatic carcinoma was also found in a separate nodule from the abdominal wall. The patient had an uncomplicated post-operative period, and survived several months thereafter. CONCLUSIONS: Metastasis of laryngeal SCC to the small bowel with perforation is exceedingly rare, but possible. These patients may be successfully managed with resection.

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.
