Extensive Rokitansky-Aschoff sinuses in a 64 year ood woman. A. Extending from a benign, chronically inflamed plicae are Rikitansky-Aschoff sinuses. Note their travel in between muscle bundles can be recognized as continuity to the surface. B. In between the gall stone at lower left and the lymphoid aggregate at upper right lies the gallbladder wall. Note the longitudinal extensions of the Rokitansky-Aschoff sinuses, as well as the ballooning outside the wall at lower right. C. The mucosa shows extensive reactive branching. Note again the predominant extension between muscle bundles, recognizable by the stroma about the sinuses, some of which are branched, pushing the muscle wall aside. There is no desmoplasia, but some gallbladder azdenocarcinomas show little recognizable desmoplasia. D. The focus on the right is difficult to identify as lying between muscle bundles. The triple parallel tubules argue against neoplasia. The lack of cancerous nuclear change is important as well. | |||
