Acinar Pattern of Mammary Paget?s Disease: A Case Report
Bibliographic record
Abstract
Mammary Paget's disease (MPD) is an uncommon in situ neoplasm of the nipple-areolar complex and surrounding skin. It is almost always associated with mammary ductal carcinoma in situ (DCIS), high-grade or invasive carcinoma, usually of ductal origin. MPD has only rarely been described in association with specialized forms of breast carcinoma. We report an unusual case of an acinar pattern of MPD with low-grade cytological atypia, associated with invasive papillary carcinoma and micropapillary DCIS of the lactiferous ducts, in an 83-year-old woman. Most cases of MPD are characterized by intraepidermal spread of discohesive glandular epithelial cells with high-grade nuclear atypia. A predominant acinar pattern of MPD is extremely uncommon and, to our knowledge, has not been formally reported. The histological features and differential diagnosis are discussed.

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.
