ABSTRACT
Background: Colorectal Cancer is the fourth most commonly diagnosed and chronological changes in colorectal polyps and cancer is important in efficacy of screening strategies. In this study, we aimed to compare clinicopathological features of colorectal polyps and also aimed to characterise the distribution and the pathological features of polyps during an 18-year period divided in to two groups.Methods: This is retrospective analysis of cases that underwent colonoscopy and found to have colorectal polyps were re-viewed retrospectively for 18 year period are retrieved. 18 year period was divided in to 2001 to 2010 and 2011 to 2018.Results: Among 4230 patients underwent colonoscopy between January 2001 and September 2018, 1356 were excluded; of the remaining 2874, 986 were found to have 1,272 polyps. 306 patients had 412 polyps in 2001 to 2010 group and 680 patients had 860 polyps in 2011 to 2018 group. Adenomas on the left sided colon were significantly higher in the first time period (40.2% vs 30%, p <0.0003). Polyps on the right sided colon were significantly higher in the second time period (37.3% vs 36.9%, p <0.0005). The most common histology in the both periods is tubular adenoma. Histology of adenomas with high grade dysplasia were significantly more in first period (12.4% vs 7.6%, p <0.005).Conclusions: Our data shows shift in polyps from left side to right side colon in recent years. There was no significant change in shift in advanced adenomas from left side to right side of colon.
ABSTRACT
Light-chain deposition disease [LCDD] is characterized by tissue deposition of the immunoglobulin light chains in multiple organs. These deposits appear similar to amyloid on routine sections, but differ in their staining properties and ultrastructural appearance. The deposits of LCCD are non -Congophilic and do not exhibit a fibrillar ultrastructure; while, the proteinaceous substance seen in primary amyloidosis is Congo red positive and fibrillar. One of the most common organs to be involved in LCDD is the kidney. Earlier reports on cases of LCDD have mostly shown simultaneous liver and renal involvement, there are very few cases in the literature describing LCDD of the liver without renal involvement. This report describes a patient who presented with severe cholestatic jaundice and liver cell failure with normal renal function
