Pathology of Spirocerca lupi associated oesopageal fibrosarcoma in a dog: A case report
Bibliographic record
Abstract
Spirocerca lupi is associated with the formation of sarcomas in the oesophagus of canines. A nine-year-old male Labrador carcass was presented for postmortem examination. The necropsy revealed gelatinization of subcutaneous fat and rounded up heart with gelatinization of epicardial fat. The liver was slightly enlarged, mottled in appearance with rounded borders. Kidney showed pitted up appearance on cortex. The prostate showed moderate enlargement. A nodule measuring about 5 × 4 cm in size was observed on the distal oesophagus just proximal to gastric cardia. On incision of nodule, a reddish worm was extracted. Histopathological examination of the nodule revealed spindle to plumpy cells arranged in intertwining whorls with little amount of collagen. Degeneration and necrosis of hepatocytes were observed around the central veins whereas cells around portal triads showing mild fatty changes. Kidney revealed mononuclear cell infiltration in the interstitium along with mild fibrosis. Intestinal mucosa revealed patches of hemorrhages, mucosal necrosis and mononuclear cell infiltration in the sub mucosa. Glandular epithelium of prostate showed papillary like projections into the lumen. Based on gross and histopathological examination, the case was diagnosed as Spirocerca lupi induced oesophageal fibrosarcoma.

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.
