Primary Cardiac Epithelioid Angiosarcoma in a Latin American Patient: Case Report and Literature Review

Figure 3

(a) Microphotography H&E (20x). In the center, we can observe a blood vessel surrounded by neoplastic cells in two different patterns: cells forming nests and spindle cells fusing with each other. (b) Microphotography H&E (40x). The tumoral cells are shown in detail, with a medium to large size, scant cytoplasm, oval nuclei of vesicular chromatin, prominent nucleolus, and several mitotic figures. (c) Immunochemistry of the CD31 marker: the neoplastic cells’ cytoplasm and membrane are positive, while the bronchial epithelium is negative.
