Tuberous Breast: Morphological Study and Overview of a Borderline Entity
Bibliographic record
Abstract
BACKGROUND: Tuberous breasts are widely known and described. Several surgical strategies have been proposed; however, few studies explain the origin or structural alterations of this deformity. No histological studies have been performed. The present article describes a morphological and histological study of breast tissue specimens. METHODS: Mammary specimens of 22 female and five male patients with tuberous breasts were histologically analyzed and compared with six specimens harvested from normal female breasts and from three cases of true 'normal' gynecomastia. RESULTS: A high prevalence of one histological subtype was observed, with the presence of collagen fibres among few fibroblasts. Histochemical analysis highlighted alterations of the arrangement and of the quantity of collagen involving breast structures. CONCLUSIONS: Results of the present study suggest that collagen deposition alterations can better explain breast parenchyma modifications. Histological features of male subjects support this theory. Additionally, the observation of two cases in male homozygous twins suggests the role of genetic influences.

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.
