Abstract:
A case of serrated adenomatous polyp found in a cholecystectomy specimen is reported. The adenoma was built with mucosal crypts exhibiting unlocked serrations lined with up to high-grade dysplastic cells. A desmoplastic sclerotic tissue having multiple stromal hubs with branched thin spokes replaced the subjacent lamina propia, muscularis mucosae, and submucosa. The generous serrated configurations covering a multi-branched sclerotic stroma, gave the adenoma a papillary appearance. Review of the literature indicates that this appears to be the first reported case of serrated adenoma of the gallbladder.
