Primary biliary cirrhosis (PBC) is an autoimmune, slowly progressive, cholestatic, liver disease characterized by a triad of chronic cholestasis, circulating anti-mitochondrial antibodies (AMA), and characteristic liver biopsy findings of nonsuppurative destructive cholangitis and interlobular bile duct destruction. Faa G, Van Eyken P, Demelia L, Vallebona E, Costa V, Desmet VJ. Semin Diagn Pathol. Alternatively, examination of serial sections can also show actual disappearance of affected bile duct.3,42, Jay H. Lefkowitch MD, in Scheuer's Liver Biopsy Interpretation (Tenth Edition), 2021, Bile-duct adenomas are small, grey-white, usually subcapsular nodules measuring from 1 to 20 mm in diameter,98 which may represent hamartomatous peribiliary glands or reactive biliary lesions with features of foregut pyloric metaplasia, rather than a neoplasm.99,100 They are more often solitary than multiple.

Visual survey of surgical pathology with 11,373 high-quality images of benign and malignant neoplasms & related entities. Other causes of bile-duct damage include AIH,129 bile-duct obstruction with suppuration, graft-versus-host disease and rejection of a grafted liver. Because in viral hepatitis the duct damage is focal and does not lead to extensive duct loss, the clinical and biochemical picture is not necessarily cholestatic. The book starts by reviewing normal structure and its variants and the optimal approaches for the preparation of histological sections for diagnostic liver pathology. Granulomatous hepatitis with eosinophilia has been attributed with mebendazole [11].. A 52-year-old man with ascariasis took two 3-day cycles of mebendazole 100 mg bd with a 2-week interval.Within 48 hours of the second course he developed fever (39 °C), diarrhea, anorexia, and prostration.Ten days later he had tender hepatomegaly. Cholestasis The morphological definition of cholestasis is presence of bile Vanishing bile duct syndrome (VBDS) is a rare but serious outcome and complication of drug induced liver injury marked clinically by chronic cholestasis and histologically by loss of intrahepatic bile ducts. There is a further reason, no less important than the others: without a knowledge of acute hepatitis, the pathologist cannot hope to understand chronic hepatitis and cirrhosis, together the cause of most liver disease in the world.

Introduction. Targeted immunotherapy as a potential treatment for cancer has been intensively studied over the past decade [1, 2].Tumor cells often use multiple resistance mechanisms to evade the host immune system [3, 4].Checkpoint proteins, such as programmed cell death-1 (PD-1) on T lymphocytes and PD-1 ligand (PD-L1) receptors on tumor cells, allow tumor cells to keep the host … In addition, abscess formation may occur but is exceptional in most cases of bile duct obstruction, whereas abscesses are the rule in recurrent pyogenic cholangiohepatitis. The denser parts of this infiltrate are mainly composed of lymphocytes, which may form aggregates or follicles with germinal centres (Fig. Idiopathic adulthood ductopenia is a diagnosis of exclusion characterized by absence of interlobular bile ducts in more than 50% of portal tracts in a patient with a cholestatic serologic profile. Histopathology: Methods and Protocols provides a comprehensive guide to the current issues in histopathology.

Small portal tracts may merely show ‘non-specific’ portal inflammation, in which case step sections may make the true diagnosis clear by revealing bile-duct lesions or granulomas. ... making the practice of pathology easier, better, and faster. The basement membrane becomes disrupted, and the duct may rupture (Fig. Likewise, ductopenia does not always prove chronic biliary tract disease because it can be seen with a variety of diseases (see Table 4.5). Inadequate clinical history and multiple drugs being taken simultaneously often compound the problem. The task is further rendered difficult on biopsy, as drugs can mimic all the patterns found in primary liver disease. ays were used for genotyping. Pathology of impaired blood flow Bile flow may be interrupted due to damage or obstruction anywhere along the biliary tree. Evaluation of a liver biopsy in a suspected case of drug-induced liver injury (DILI) can be a daunting experience. In this review, these have been divided as belonging to one of three categories: (1) new-onset/de novo post-transplant abnormalities (early and late), (2) rejection, and (3) recurrence of original disease. Bile duct paucity in childhood-spectrum, profile, and outcome. The diagnosis is made pathologically, although it can be suggested on imaging tests such as ERCP MRCP when disease is advanced.
