Abstract
The cytomorphological aspects of a mammary angiosarcoma in a 44 year-old woman are presented. The imprint cytology of the resected mastectomy specimen revealed a small number of scattered isolated cells and variously sized cellular clusters. The clusters were characterized by a mixture of centrally oriented spindle shaped cells and peripherally located epitheloid-like oval-to-polygonal cells forming papillary projections. These features correlated well with the intraluminal papillary patterns in the histological sections and also agreed with many of the cytological features of angiosarcoma which previously described in the literature. The characteristic cellular pattern with mixed spindle cells and epitheloid-like cells in clusters as seen in this case, although not reported previously, may be of diagnostic value.
