Chronic pancreatitis is an inflammatory process characterized by the destruction of pancreatic parenchyma and ductal structures with the formation of fibrosis. Endoscopic Ultrasound (USE) allows the visualization of changes in the parenchyma and pancreatic duct, allowing the identification of specific criteria for chronic pancreatitis early. Objective: Correlate cyto morphologically the changes of the echoestructure of the pancreas in areolar patterns with hyper and hypoechoic areas and cyto-histological changes obtained by fine needle aspiration suggestive of chronic pancreatitis, fibrosis and/ or steatosis. Method: Were included 8 patients who underwent upper USE presenting criteria of areolar chronic pancreatopathy mild to severe. A fine needle aspiration of the hyperechoic and hypoechoic areas was performed and processed with special fast colorations and cell block study, in a blind way, separately, for the cytohistological study. Data were emptied into tables and analyzed in percentages. Results: The most frequent changes in hyperechoic areas were the presence of inflammatory infiltrate, fibrosis, calcification, steatosis and bleeding. There were no differences in the presence of detritus, fat necrosis and proteinaceous material. In cell types do not seems to be differences, however, acinar cells were observed in greater proportion, followed by ductal and occasionally islet, mostly with moderate reactive and degenerative changes. Conclusion: There are reactive changes demonstrated by cytohistology in patients with pancreatopathy in areolar patterns in USE suggesting chronic inflammation and fibrosis, studies with larger populations should be conducted to establish degrees of severity.
