A 70-year-old woman underwent a partial mastectomy with preoperative diagnosis of phyllodes tumor. Histopathological examination of the resected specimen revealed noninvasive ductal carcinoma of up to 20 mm in the phyllodes tumor. We note the possibility of a situation in which a phyllodes tumor is accompanied by cancer, and detailed pathological examination is necessary.

Point mutations in the ligand binding domain of retinoic acid receptor alpha (RARα) are linked to breast fibroepithelial tumor development, but their role in solid tumorigenesis is unclear. In this study, we assessed the functional effects of known RARα mutations on retinoic acid signaling using biochemical and cellular assays. All tested mutants exhibited reduced transcriptional activity compared to wild-type RARα and showed a dominant negative effect, a feature associated with developmental defects and tumor formation.

Breast sarcomas are a diverse group of malignant neoplasms originating from the mammary stroma. They are uncommon tumors, often occurring as a component of other tumors. Among malignant breast mesenchymal tumors, pure sarcomas lacking epithelial components are even rarer, comprising only 0.

However, diagnostic challenges with core biopsy specimens often result in suboptimal surgical margins. This study aims to elucidate the correlation between margin status and PT recurrence, thereby informing surgical decision-making and enhancing patient outcomes.
