Large cell change (LCC) is a noncommittal term used today to indicate liver cell dysplasia of the large cell type. Dysplasia was deleted from the original definition because not enough evidence has been collected over time to support premalignancy. LCC is a microscopically well-defined lesion, usually found in cirrhosis, whose ...
