(2014) divided crista galli in three groups considering its relationships with cribriform lamina of the ethmoid bone: type I--crista galli situated entirely above the lamina cribriformis, type II--crista galli situated less than 1/2 of its height under the lamina cribriformis, type III--crista galli situated more than 1/2 of its height under the lamina cribriformis.
(23) have reported preliminary evidence that advanced morphologic features, such as cribriform, influences the visibility of prostate lesions more so than tumors of the same grade with differing architectural patterns.
It is now recognized that GP 4 in conventional acinar adenocarcinoma has 4 basic patterns: cribriform, fused, poorly formed, and glomeruloid glands (Figure 3, A through D).

Importantly, the involved glands were not completely filled or distended by the foamy cells nor did they show dense or loose cribriform or micropapillary architecture, marked nuclear atypia or comedo-type necrosis that would have suggested a diagnosis of intraductal carcinoma with foamy features.
Features previously reported to be associated with HGD diagnosis (nuclear pleomorphism, loss of nuclear polarity, architectural complexity, cribriform glands, and/or papillary configuration) and stratification reaching more than half way of the crypt epithelium thickness [6] were also evaluated by the reviewers.
