Hilar cholangiocarcinoma associated with immunoglobulin G4‐positive plasma cells and elevated serum immunoglobulin G4 levels
Immunoglobulin G4 (IgG4)-related disease is a fibroinflammatory systemic disorder with multiorgan involvement. Proximal bile duct involvement results in IgG4-related sclerosing cholangitis, which is characterized by a lymphoplasmacytic infiltrate with abundant IgG4-positive plasma cells and fibrosis. Differentiating between cholangiocarcinoma and IgG4-sclerosing cholangitis can present a diagno...
متن کاملImmunoglobulin G4-associated sclerosing cholangitis mimicking cholangiocarcinoma.
Immunoglobulin G4-related lymphoplasmacytic sclerosing disease is an emerging disease. Recently, it has been shown to be responsible for autoimmune pancreatitis-induced strictures of the bile duct mimicking cholangiocarcinoma. Making a diagnosis of immunoglobulin G4-associated sclerosing cholangitis requires a high index of suspicion. The differential diagnoses include primary sclerosing cholan...
متن کاملImmunoglobulin G4–Related Sclerosing Cholangitis Mimicking Hilar Cholangiocarcinoma Diagnosed With Following Bile Duct Resection: Report of a Case
We report a rare case of immunoglobulin G4 (IgG4)-related sclerosing cholangitis without other organ involvement. A 69-year-old-man was referred for the evaluation of jaundice. Computed tomography revealed thickening of the bile duct wall, compressing the right portal vein. Endoscopic retrograde cholangiopancreatography showed a lesion extending from the proximal confluence of the common bile d...
متن کاملDifferentiating Immunoglobulin G4-Related Sclerosing Cholangitis from Hilar Cholangiocarcinoma
BACKGROUND/AIMS Few studies have differentiated immunoglobulin G (IgG) 4-related sclerosing cholangitis (IgG4-SC) from hilar cholangiocarcinoma (CC). Thus, we sought to investigate useful features for differentiating IgG4-SC from hilar CC. METHODS We retrospectively compared clinical, serological, imaging, and histological features of six patients with IgG4-SC and 42 patients with hilar CC. ...
متن کاملMetastatic breast cancer mimicking a hilar cholangiocarcinoma: case report and review of the literature
BACKGROUND/AIMS Breast cancer is the most common tumor in women and the first cause of death for malignancy in the female population. Bile ducts are not among the common sites of metastasis from breast cancer; few cases of obstructive jaundice due to metastatic breast cancer have been described in the literature and they mostly resulted from widespread liver metastases that eventually involved ...
