desc11 = 'Case 1 - Figure 1
Heart in-situ with large well circumscribed mass overlying right atium. On right a probe elevates the mass exposing the compressed, distorted right atrium ';
desc12 = 'Case 1 - Figure 2
A transverse, cross section of the thorax. Right and left lungs are connected by the branch pulmonary arteries with a cross section of the ascending aorta situated near the left lung hilum. The tumor is attached to the anterior and rightwards border of the aorta. The tumor has a fleshy, tan-white cut surface with two central cystic spaces and focal hemorrhage. The section is taken superior to the heart ';
desc13 = 'Case 1 - Figure 3
A low power (2x), H & E section through the tumor demonstrating the point of attachment to the root of the aorta (the large vessel in the central-top portion of the image). The tumor has a heterogeneous composition. Myocardium of the right ventricular outflow tract is evident in the right upper corner of the image and is not infiltrated by tumor ';
desc14 = 'Case 1 - Figure 4
H & E sections of the tumor demonstrating the heterologous composition with attempted organogenesis. The image to the left shows a cystic space lined by ciliated respiratory epithelium with surrounding mesenchyme and smooth muscle simulating a bronchiole (40x). On the right, the top image shows a nodule of cartilage (20x) and the bottom shows striated muscle (40x). The middle image shows pancreatic tissue with acini and islets (20x) ';
desc15 = 'Case 1 - Figure 5
A medium power (10x) H & E section of the tumor demonstrating, on the left, a large cystic space lined by hyperchromatic, immature neuroepithelium simulating the neural tube. The neuroepithelium merges with irregularly shaped tubules lined by columnar and cuboidal epithelium, all dispersed within a moderately cellular, pale staining, immature mesenchyme ';
desc16 = 'Case 1 - Figure 6
A low power (2x) H & E section of the tumor demonstrating aggregates of tubules, and solid nests and cords of cells disposed within a stroma that varies in cellularity and density. The very pale, nearly clear, mucinous regions of the stroma should be closely examined for the presence of yolk sac tumor ';
desc17 = 'Case 1 - Figure 7
H & E images of the clear, mucinouspale areas of stroma show solid nests (right image 10x), cords and loosely dispersed tumor cells (left image 4x) of yolk sac tumor (left 4x, right 10x) ';
desc18 = 'Case 1 - Figure 8
High power, (40x) H & E images of monotonous, tumor cells with a delicate nuclear chromatin pattern, occasional nucleoli, and scant, relatively clear cytoplasm of malignant yolk sac tumor ';
desc19 = 'Case 1 - Figure 9
High power (40x) H & E image of hepatic differentiation. The image on the left shows areas of the teratoma with immature fetal liver morphology with congestion/hemorrhage within sinusoids. The image on the right shows clusters of hepatoid pattern of yolk sac tumor surrounded by typical yolk sac tumor morphology ';
desc10 = 'Case 1 - Figure 10
Intermediate power (20x) H & E image of primitive endodermal glands representing well differentiated yolk sac tumor. The glands are lined by cells with basal, subnuclear vacuoles and are dispersed within immature stroma ';
desc21 = 'Case 2 - Figure 1
Low power view of cardiac myxoma with focal glandular elements ';
desc22 = 'Case 2 - Figure 2
A higher magnification of the glandular component; the glands have irregular contours and are lined by cuboidal to columnar cells ';
desc23 = 'Case 2 - Figure 3
An area of cardiac myxoma composed of myxoma cells found in a myxoid matrix ';
desc31 = 'Case 3 - Figure 1
A section of the neoplasm ';
desc32 = 'Case 3 - Figure 2
A section of the neoplasm ';
desc33 = 'Case 3 - Figure 3
A section of the neoplasm ';
desc41 = 'Case 4 - Figure 1
"Vegetation from" mitral valve. Note vacuoles and focus of dense connective tissue (x 20) ';
desc42 = 'Case 4 - Figure 2
The "vegetation" is composed predominantly of oval to round cells with abundant pink cytoplasm (x 40) ';
desc43 = 'Case 4 - Figure 3
Interspersed among the round cells are clusters and strips of columnar cells, some of which have prominent nucleoli (x 200) ';
desc44 = 'Case 4 - Figure 4
The columnar cells are reactive with antibodies to CK 5/6 (x 400) ';
desc45 = 'Case 4 - Figure 5
The round cells are reactive with antibodies to CD 68 (x400) ';
