Extratesticular interstitial and Sertoli cell tumors in previously neutered dogs and cats: a report of 17 cases.
Bibliographic record
Abstract
Primary neoplasms derived from testicular tissue and in an extratesticular location are extremely rare. Clinical and surgical information was collected and verified from 15 different submitting practices for 12 dogs and 5 cats that spontaneously developed neoplasms of testicular origin after castration. Eleven dogs had Sertoli cell tumors in an extratesticular location. One dog and all 5 cats had an extratesticular interstitial cell tumor. Six animals (1 dog, 5 cats) had developed secondary sexual characteristics that reversed after removal of the tumor. All had a palpable mass in the scrotum or at the site of the original prescrotal incision. No animals died of neoplasia-related disease and no metastases were identified. Several possibilities, including the presence of embryological ectopic tissue or the presence of testicular tissue transplanted during castration, are considered as causal.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
