Epithelial Carcinomas Arising within Phyllodes Tumours of the Breast: A Review of Their Pathological Characteristics.
Epithelial proliferation is a common feature of phyllodes tumours (PTs), but epithelial malignancy is rare. This review seeks to further our understanding of epithelial malignancy within PTs by analysing their histopathological characteristics in previously reported cases and providing an overview of studies on their pathological features. PubMed and DeepDyve were searched for case reports, case series, and literature reviews of in situ and invasive carcinoma within PTs. Only cases where the carcinoma was within the PT were included. Cases of synchronous carcinoma in the ipsilateral or contralateral breast were excluded. Ninety-eight cases of in situ or invasive carcinoma within a PT were identified. Across the grades of PTs, there was a similar proportion of invasive carcinomas compared to in situ lesions. Malignant PT correlates with a higher likelihood of epithelial malignancy, and molecular studies support a possible causal pathophysiological relationship. This higher likelihood may suggest interactions between malignant stroma and the transforming epithelium that could potentially play a significant role in the phenomenon, which remains to be elucidated. Encasement within a PT likely improves the prognosis of breast carcinoma due to earlier detection. The presence of carcinoma within a malignant PT has uncertain prognostic implications. Thorough sampling of all PTs is recommended for appropriate prognostication and management.
期刊介绍:
''Pathobiology'' offers a valuable platform for the publication of high-quality original research into the mechanisms underlying human disease. Aiming to serve as a bridge between basic biomedical research and clinical medicine, the journal welcomes articles from scientific areas such as pathology, oncology, anatomy, virology, internal medicine, surgery, cell and molecular biology, and immunology. Published bimonthly, ''Pathobiology'' features original research papers and reviews on translational research. The journal offers the possibility to publish proceedings of meetings dedicated to one particular topic.
