SEROUS CYSTADENOFIBROMA Figure 4-1 SEROUS CYSTADENOFIBROMA Left: Serous cystadenomas have a grossly multilocular appearance, with a fibrous intervening stroma. Right: Papillary excrescences may be confused with borderline tumors, and diagnosis should not be based only on the gross findings.

SEROUS CYSTADENOFIBROMA Figure 4-2 SEROUS CYSTADENOFIBROMA Left: At low power, serous cystadenomas often show papillary growth with thick, blunt papillae. Right: The stroma in the papillae can be either fibrotic (eosinophilic papillae, left) or edematous (clear papilla, right). Exfoliation of sm...

SEROUS CYSTADENOMA Figure 4-3 SEROUS CYSTADENOMA A: The epithelium of a serous cystadenoma is nonstratified, consisting of secretory and ciliated cells. B: Sometimes cells have secretory “snouts.” C: Recognizable serous differentiation is sometimes a focal finding, and in some tumors, the epith...

SEROUS BORDERLINE TUMOR Figure 4-7 SEROUS BORDERLINE TUMOR A: Grossly, serous borderline tumors can show an extensive intracystic proliferation of small papillae. B: These papillae can completely fill the cyst. C: Inking the surface helps to identify surface growth. Sometimes, on gross examinat...

SEROUS BORDERLINE TUMOR Figure 4-8 SEROUS BORDERLINE TUMOR A: At low power, serous borderline tumors show hierarchical branching, with large papillae giving rise to medium-sized papillae and finally small micropapillae. Occasionally, the proliferation is compact. B: The presence of exfoliation of small cell groups is required for the diagnosis. The presence of extensive eosinophilic cells has been associated with the presence of a BRAF V600E mutation. C: Just like a cystadenoma, the papillae can be fibrotic or edematous. D: The grade of nuclear atypia does not exceed that allowed for low-grade tumors. More about this image found in SEROUS BORDERLINE TUMOR A: At low power, serous borderline tumors show hie...

LOW-GRADE SEROUS TUMOR Figure 4-15 LOW-GRADE SEROUS TUMOR Left, right: This low-grade serous tumor represents extensive fusion of the epithelium, similar to the surface cribriform growth pattern depicted in fig. 4-11 . This type of proliferation is difficult to classify, but in the absence of st... More about this image found in LOW-GRADE SEROUS TUMOR Left, right: This low-grade serous tumor represents...
