Solitary pulmonary metastasis at presentation in a dog with anal sac adenocarcinoma without nodal metastasis
Bibliographic record
Abstract
Abstract A 10‐year‐old, male, neutered labrador retriever was diagnosed with a left‐sided anal sac adenocarcinoma. At diagnosis, staging with an abdominal computed tomography revealed no intraabdominal lymph node enlargement. Thoracic radiographs revealed a soft tissue pulmonary nodule with cytology consistent with a carcinoma. The dog underwent a left anal sacculectomy, and re‐presented 24 days later for a lung lobectomy in which histopathology represented primary anal sac adenocarcinoma metastasis. Forty‐nine days after initial presentation, the dog was referred for a right distal radial lytic lesion in which cytology was concerning for osteosarcoma. After 132 days of initial presentation, an abdominal ultrasound revealed normal‐sized iliosacral lymph nodes. The dog was humanely euthanased 446 days after initial diagnosis. This case report describes a dog who had a solitary metastatic pulmonary nodule from apocrine gland anal sac adenocarcinoma at the time of presentation with no nodal metastasis identified, which is atypical compared to previous reports.

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.
