title: Gastric multicentric glomangioma: a case report of this rare cause of abdominal pain.
abstract: BACKGROUND
  A glomus tumor is a rare neoplasm derived from glomus cells, specialized cells that surround small blood vessels which are important in regulating peripheral blood flow. Glomangiomas are a subset of glomus tumors. They are usually localized in the skin and subcutaneous tissue. They have also been reported in viscera, most notably in the gastrointestinal tract.
  
  
  METHODS
  A case of gastric multicentric glomangioma is described in an 18-year-old male who presented with chronic continuous abdominal pain over a 4-6 month period. Preoperative diagnosis, operative findings, histology, and immunohistochemistry of the tumor are discussed in detail.
  
  
  CONCLUSIONS
  Case reports of this rare tumor are important because of the paucity of studies noted in the gastro-intestinal literature as a result of poor identification prior to the advent of modern immunohistochemistry. The significance of accurately diagnosing a gastrointestinal glomangioma is crucial for appropriate treatment.
