Background Phyllodes tumor (PT) of the breast is an uncommon fibroepithelial neoplasm. Malignant epithelial transformation in PT is rare. This study reports clinicopathologic characteristics and outcomes of patients with malignant epithelial transformation in PT.

We report a case of an epithelioid angiosarcoma that involved the right atrium and aorta of a 47-year-old male. The patient presented with atrial fibrillation and presyncopal spells.

Three hundred eighteen patients were assigned to receive no further therapy or radiation therapy (37.5 Gy in 16 fractions).

We aimed to start molecular characterisation of these rare neoplasms and to do a genome-wide search for new diagnostic markers.
Methods: We analysed gene-expression patterns of 41 soft-tissue tumours with spotted cDNA microarrays.
Objective: The objective of our study was to describe the MR imaging features of 10 cases of histologically confirmed dermatofibrosarcoma protuberans.
Conclusion: MR imaging is useful in identifying the extent and location of dermatofibrosarcoma protuberans. Although most cases of this tumor are superficial and well defined, we have shown three cases in which the tumor was in a deep location and one case in which the tumor was ill defined in appearance.
