Background: Leiomyoma of the pancreas is an extremely rare entity. There are currently only three reported cases, all of which were small, asymptomatic, and incidentally found tumor.
Methods: We have reported the first case of leiomyoma of the pancreas in a young woman with a large symptomatic mass.
Results: A 31-year-old woman presented with chronic abdominal pain. Computed tomography scans showed a huge heterogeneously enhancing mass, located between duodenum and pancreatic head. The patient underwent pancreaticoduodenectomy and the histology confirmed leiomyoma of the pancreas.
Conclusions: This case adds the knowledge that this extremely rare entity could be manifested as symptomatic mass in a young patient.
Keywords: Leiomyoma; Mesenchymal tumor; Pancreas.
