Figure 2.

Morphology of the cavitronic ultrasonic surgical aspiration (CUSA) and FFPE specimens from several tumors. Specimens for GBM1, GBM2, GBM4, and LCM1 are shown in the first, second, third, and fourth rows, respectively. The original magnification for the first column (panels A, D, G, and J) was at 100X and the others were at 400X. Comparable morphology of the ultrasonic aspiration and FFPE specimens from each tumor is noted in the high power views shown in the last 2 columns. Cellular pleomorphism and mitoses were prominent. Characteristic regions of necrosis and vascular proliferation were also found in the FFPE sections of the GBMs (not shown). Several clinicopathologic features are listed in Table 2. The portions of the CUSA specimens shown had been processed in the same manner as the FFPE specimens. Hematoxylin and eosin stain. Magnifications bars represent 100 micrometers.
