Suspected canine primary lymph node mast cell tumor.
Bibliographic record
Abstract
An 8-year-old spayed female Chihuahua dog was diagnosed with a suspected primary mast cell tumor (MCT) of the left popliteal lymph node (LN). Physical examination, computed tomography, and focused hind-limb ultrasound failed to identify a primary integumentary MCT. Asymmetry of the ipsilateral medial iliac LN was identified on abdominal ultrasound. Surgical excision of the left popliteal and left medial iliac LN was completed without complication. Histologic assessment confirmed overt MCT effacement of both LN. Postoperatively, the dog received adjuvant chemotherapy (vinblastine and prednisone). The dog was alive 562 d after surgery, without evidence of disease recurrence. To the authors' knowledge, this is the first report in the veterinary literature documenting a suspected canine primary LN MCT. Key clinical message: Albeit rare, primary LN MCT should be a differential diagnosis for lymphadenopathy in the absence of a primary integumentary tumor.

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.
