Phyllodes tumor of the breast is an uncommonly encountered disease. The tumor presenting as fungating breast mass or 'ruptured' breast is an even more rare presentation of an unusual disease. This report documents the case of a 60-year-old female with delayed presentation of a large exophytic mass of the left breast. Biopsy of this lesion was non-diagnostic, so excision via left total mastectomy was performed. The final pathology was consistent with malignant phyllodes tumor. This report highlights the features of a rare breast cancer, the challenges in obtaining a definitive diagnosis, and the treatment of this disease, in an effort to provide clinicians with an example of the management of such a peculiar entity.

Phyllodes tumor is a type of fibroepithelial neoplasm involving the breast. This tumor is rarely reported in adolescents and the elderly and has a peak incidence in middle-aged women. Histologically, phyllodes tumors are classified as benign, borderline, or malignant.

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.
