Myofibroblastoma of the Male Breast: a Typical Case Report and Narrative Review
Bibliographic record
Abstract
Myofibroblastoma (MFB) is a rare stromal benign tumor that arises from the breast tissue, composed by fibroblasts, myofibroblasts and adipocytes.MFB typically presents as a solitary, painless mass in the breast, predominates in 60-80 yearsold adult males and is rarer in postmenopausal women.It could be diagnosed by a combination of imaging and pathological tests, even if its imaging features are nonspecific, often leading to misdiagnosis.Biopsy is always needed for definitive diagnosis.Wide local excision, with no need of sentinel lymph node biopsy, is curative since local recurrence is extremely low and has been reported to be less than 1.5%.We report herein the case of MFB in a 61-year old male presenting with a nodule on the left breast and review the literature focusing on differential diagnosis.

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.
