Sclerosing peritonitis associated with gynecological tumors: IgG4 peritoneal disease or a low grade spindle cell neoplasm?

IgG4-related sclerosing disease.

Based on histological and immunohistochemical examination of various organs of patients with autoimmune pancreatitis (AIP), a novel clinicopathological entity of IgG4-related sclerosing disease has been proposed. This is a systemic disease that is characterized by extensive IgG4-positive plasma cells and T-lymphocyte infiltration of various organs. Clinical manifestations are apparent in the pa...

Sclerosing Stromal Tumor: A Rare Ovarian Neoplasm

Ovarian sex cord-stromal tumors are relatively infrequent neoplasms that account for approximately 8% of all primary ovarian neoplasm. Sex cord-stromal tumors of the ovary include granulosa cell tumors, fibrothecomas, Sertoli-Leydigcell tumors, steroid cell tumors, and sclerosing stromal tumors (SST). Sclerosing stromal tumors account for 2% to 6% of ovarian stromal tumors. Despite the rarity o...

Extensive Metastatic Cholangiocarcinoma Associated With IgG4-Related Sclerosing Cholangitis Misdiagnosed as Isolated IgG4-Related Sclerosing Cholangitis

As cholangiographic features of IgG4-related sclerosing cholangitis (IgG4-SC) resemble those of cholangiocarcinoma, it is highly confusing between the 2 conditions on the basis of cholangiographic findings. This study presents a case of extensive metastatic cholangiocarcinoma with IgG4-SC misdiagnosed as isolated IgG4-SC, and reviews recent studies of the 2 diseases.A 56-year-old man with no fa...

Spindle cell hemangioma or hemangioendothelioma: A case report

Spindle cell hemangioma is a benign vascular tumor presenting as multifocal red or bluish nodules on the distal limbs. We present a 57-year-old woman with five years history of multiple, soft, violaceous nodules on her hands. Pathologic study indicated spindle cell hemangioma.
