A Curious Case of Autoimmune Pancreatitis with IgG4-related Sclerosing Cholangitis.

Immunoglobulin G4-related sclerosing cholangitis (IgG4-SC) is a novel entity that belongs to the immune-mediated fibroinflammatory class of IgG4-related diseases (IgG4-RD). IgG4-SC is noted to be one of the most frequent manifestations of extra-pancreatic disease among IgG4-RD, which is significantly different from primary SC (PSC) and cholangiocarcinoma (CC) as is evident in the varied approaches to treatment. IgG4-RD includes IgG4-SC and autoimmune pancreatitis (AIP).

A Rare Case of Mixed Adenoneuroendocrine Carcinoma of the Ileocecal Valve.

Mixed adenoneuroendocrine carcinoma (MANEC) is an uncommon neoplasm with uncertain pathophysiology. In order to be classified as MANEC, the tumor must contain at least 30% neuroendocrine cells and 30% adenocarcinoma. The standardization of MANEC treatment has historically been difficult due to the lack of diagnostic histological classification.

Hereditary Colorectal Tumors: A Literature Review on MUTYH-Associated Polyposis.

MAP (MUTYH-associated polyposis) is a syndrome, described in 2002, which is associated with colorectal adenomas, with enhanced colorectal carcinogenesis. This review synthesizes the available literature on MAP and outlines its pathogenesis, association with colorectal tumorigenesis, screening, treatment, and the subtle differences between it and its close cousins-FAP and AFAP. The preponderance of data is collected using MAP guidelines.

A Rare Cause of Dysphagia to Remember: Calcific Tendinitis of the Longus Colli Muscle.

Longus colli tendinitis (LCT) is an acute inflammatory condition with symptoms typically consisting of acute neck pain and stiffness with or without dysphagia. Once more severe etiologies for these symptoms are ruled out, this self-limiting condition usually resolves spontaneously with nonsteroidal anti-inflammatory drugs and corticosteroids. We present a case of LCT that presented as acute neck pain, dysphagia, and odynophagia that rapidly resolved once diagnosed and treated with anti-inflammatory agents.
