1/2. Aspiration cytology of sarcomatoid carcinoma of the breast: Report of a case with cystic change.Sarcomatoid/metaplastic carcinomas of the breast are rare breast malignancies that show a myriad of cytohistologic patterns in aspirates. These poorly differentiated invasive carcinomas contain both ductal and mesenchymal elements with transitional forms displaying either spindle, squamous, chondroid, or osseous differentiation. We describe such a neoplasm in a 68-yr-old woman, the diagnosis of which was missed at the initial fine-needle aspiration (FNA) due to cystic change. Extensive cystic change in a sarcomatoid carcinoma is unusual and is reported for the first time in the English literature.- - - - - - - - - - ranking = 1keywords = ductal, neoplasm (Clic here for more details about this article) |
2/2. A case of intracystic breast cancer.The case of a 70-year-old female patient with family history of breast cancer come to the breast Unit for the presence of a nodular swelling in the right breast is discussed. On mammography and US a gross cystic neoformation with vascularized mural nodes was identified. Another contralateral solid nodular neoformation suggestive of malignancy was also present. Diagnostic completion with MRI confirmed the mixed solid, partly cystic nature of the right lesion, leading to the differential diagnosis with cystosarcoma phylloides and intracystic tumor. On the left side, MRI confirmed the presence of the second lesion whose morphologic and dynamic characteristics suggested a neoplastic lesion. At the anatomopathological examination the left lesion was shown to be an infiltrating ductal carcinoma; the right lesion was shown to be an intracystic tumor.- - - - - - - - - - ranking = 0.95810619059725keywords = ductal (Clic here for more details about this article) |
