A rare case of lipomatous pseudohypertrophy of the pancreas.

Lipomatous pseudohypertrophy of the pancreas is a rare disease with unknown etiology, and the pancreas parenchyma is replaced by pancreatic parenchyma by fat tissue. In this article, we aimed to report the case of a 26-year-old male patient admitted to hospital with loss of appetite for 6 months. Abdominal computed tomography (CT) and magnetic resonance imaging (MRI) scans showed diffuse enlargement and fatty replacement over the whole pancreas, with scattered remnants of pancreatic parenchyma. Histologic results defined lipomatous pseudohypertrophy of the pancreas. To summarize, this case report is to put forward this extremely rare presentation and to sensitize clinicians that this entity can be a cause of exocrine pancreatic insufficiency, which requires patient follow-up for the appropriate treatment.
