@entity652 , also known as @entity652 , glycogen-rich @entity9296 or @entity12679 , is an uncommon @entity5 . We have studied 11 cases involving eight @entity1 and three @entity1 . The average age at diagnosis was 61.7 years. Four @entity5 were discovered incidentally. @entity5 varied from 1.2 to 20 cm in maximum diameter and all were multicystic. Within the pancreas, three were located in the pancreas head, one involved the head and body, one was located in the body, five were in the tail, and one occupied the whole pancreas. Central stellate scar was seen in five (45%) cases. Histologically, all @entity5 were composed of microglandular cysts lined by clear epithelial cells rich in glycogen, which were separated by fibrocollagenous stroma. The expression of keratin in clear epithelial cells resembled that in ductal and/or centroacinar cells, but not acinar cells. @entity3960 ( @entity3960 )-positive myoepithelial cells and stromal @entity527 were not detected. Ultrastructurally, fibrocollagenous stroma was composed of alpha- @entity3960 -positive myofibroblasts and endothelial cells embedded in thick collagen bundles. Regardless of female propensity, @entity172 and @entity1420 receptors were not detected. Therefore, female predominance in this @entity5 remains to be elucidated.
