Salivary Gland Choristoma: A Rare Finding at the Gastroesophageal Junction.

A choristoma is a tumor-like outgrowth consisting of heterotopic, histologically mature tissue located at an anatomically unusual part of the body. Salivary gland choristoma at the gastrointestinal junction (GEJ) is an extremely rare entity with only one other case reported in the literature. In this report, we present the case of an 87-year-old female with long-standing gastroesophageal reflux disease (GERD) history who was incidentally found to have salivary gland choristoma at GEJ through an upper endoscopy-guided biopsy. We suggest that the finding of salivary gland choristoma at the GEJ could be metaplasia secondary to the patient's long-standing history of GERD with esophagitis.

A Rare Case of Extramedullary Plasmacytoma Presenting as Massive Upper Gastrointestinal Bleeding.

Gastrointestinal (GI) involvement by multiple myeloma is a rare entity. Clinical manifestations depend on the site and extent of involvement. GI bleeding, obstruction, and perforation can complicate the disease course. We report a rare case of an extramedullary plasmacytoma ulcerating through the gastric mucosa and presenting as a massive upper GI bleed, which was controlled surgically with en-bloc resection of the mass infiltrating the stomach, distal pancreas, and spleen. To our knowledge, this is the first case of immunoglobulin A (IgA) myeloma with multiple GI organ involvement presenting with massive upper GI bleeding.
