desc11 = 'Case 1 - Figure 1
Low power view of the gastric mass shows a highly vascular, necrotic, hemorrhagic tumor ';
desc12 = 'Case 1 - Figure 2
Clusters of large tumor cells are seen within a background of dilated vessels and fibrinous debris. ';
desc13 = 'Case 1 - Figure 3
The majority of the tumor cells had bubbly purple cytoplasm with giant, bizarre nuclei. ';
desc14 = 'Case 1 - Figure 4
Small foci showed typical glandular differentiation. ';
desc15 = 'Case 1 - Figure 5
A large regional lymph node contained metastatic choriocarcinoma. ';
desc16 = 'Case 1 - Figure 6
ß-HCG immunostaining is strongly positive within trophoblastic tumor cells. ';
desc21 = 'Case 2 - Figure 1
Low-power scan of the lesion showing a well-circumscribed nodule in the submucosa. ';
desc22 = 'Case 2 - Figure 2
Medium-power view showing nests of eosinophilic spindle cells with an organoid pattern. ';
desc23 = 'Case 2 - Figure 3
High-power view showing relationship of the tumor to the overlying squamous mucosa with pseudoepitheliomatous hyperplasia. ';
desc24 = 'Case 2 - Figure 4
High-power view of tumor cells showing granular cytoplasm and single atypical nucleus. ';
desc31 = 'Case 3 - Figure 1
A low power view of eroded rectal mucosa with crypts entrapped in disorganized fibromuscular stroma. ';
desc32 = 'Case 3 - Figure 2
Rectal mucosa with crypts lined by regenerative epithelium. There is adjacent erosion and a fibrinopurulent cap. Displaced groups of hypermucinous crypts are present in the submucosa.';
desc33 = 'Case 3 - Figure 3
Same features as in Slide 2 under higher power. ';
desc34 = 'Case 3 - Figure 4
Large mucin-filled submucosal cystic spaces partially lined by simple columnar to cuboidal epithelium (colitis cystica profunda). ';
desc41 = 'Case 4 - Figure 1
Low power view demonstrating bands of fibrosis dissecting lobules of fat. ';
desc42 = 'Case 4 - Figure 2
There is extensive fat necrosis with attendant dense sclerosis. Note that the fibrous areas are paucicellular. ';
desc43 = 'Case 4 - Figure 3
Foci of dystrophic calcification are observed in areas of fat necrosis. ';
desc44 = 'Case 4 - Figure 4
Clusters of foamy macrophages are scattered throughout the areas of fat necrosis. ';
desc45 = 'Case 4 - Figure 5
In some areas, a chronic inflammatory infiltrate is present, consisting primarily of lymphocytes and plasma cells, with occasional eosinophils. ';
desc46 = 'Case 4 - Figure 6
The chronic inflammatory infiltrate also includes several lymphoid aggregates. ';
desc51 = 'Case 5 - Figure 1
Active chronic ulcer site in the antrum shows luminal fibrinoinflammatory exudate and underlying granulation tissue. ';
desc52 = 'Case 5 - Figure 2
Obliterative phlebitis is present in a submucosal vein beneath non-ulcerated gastric mucosa. The adjacent artery is normal. ';
desc53 = 'Case 5 - Figure 3
Phlebitis also involves vessels of the muscularis propria and subserosa, seen here in the duodenal wall. ';
desc54 = 'Case 5 - Figure 4
Prominent intra- and perivenular lymphoplasmacytic infiltrates. ';
desc55 = 'Case 5 - Figure 5
Granulomatous phlebitis. ';
desc56 = 'Case 5 - Figure 6
Lymphocytic gastritis in the non-ulcerated gastric antral mucosa. ';
desc57 = 'Case 5 - Figure 7
Mild lymphocytosis is also present in the duodenal epithelium, and there is associated villous blunting. ';
