Pathomorphological characteristics of of ovarian tumors in domestic animals
Bibliographic record
Abstract
Pathomorphological and clinical studies of 23 cases of ovarian tumors of dogs and cats have been carried out, which allowed to determine the morphological, clinical and anamnestic features of different histological types of ovarian tumors. Both types of animals dominated benign tumors. Malignant neoplasms were registered only in dogs, and only dogs observed proliferative tumors. 2 cases were verified as tumor-like lesions, one for each animal species. The group of epithelial tumors was the most widely reported in dogs and cats, namely different histological variants of cystadenoma. The variety of variants of cystadenoma in the dog prevailed – serous, serous proliferative, mucinous and malignant variants (cystadenocarcinoma) were observed, whereas only serous cystadenoma was diagnosed in cats. In addition to cystadenoma, adenofibroma in cats and light-cell carcinoma and Brenner`s tumors in dogs have been described. In the second place in the prevalence are the Sex Cord–Stromal Tumors. Our studies only registered granulosa-stromal cell tumors, which were represented by granulosa cell tumors of the ovary in dogs, and fibroma of the ovary in cats. Germ Cell Tumors were recorded as dysgerminoma. In both species of animals, there is a clear dependence of the appearance of neoplasm on its histological type. All neoplasms with one or more cavities referred to different variants of cystadenoma. Other histological types of ovarian tumors looked like a single, limited knot of soft or dense consistency of different sizes. At the time of detection of ovarian tumors, the age of dogs varied about 9 years, cats – about 12 years. Among the dogs of the general group, a large proportion was made by breeding animals. In the study group, dogs of the following breeds were registered: Labrador, German Shepherd Dog, Staffordshire Terrier, Caucasian Shepherd Dog and Doberman. Among the 6 cats, only one was pedigree. Tumors of ovaries in dogs and cats were almost not accompanied by clinical symptoms. In most cases, ovarian tumors were found accidentally during routine sterilization.

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.
