title: [Infantile hypertrofic pyloric stenosis or gastric adenomyoma? Differential diagnosis of gastric outlet obstruction in children].
abstract: OBJECTIVE
  Gastrointestinal adenomyoma is a rare benign tumor most frequently located in the stomach. The differential diagnosis is wide because of its large clinical spectrum and unspecific radiological findings. Surgical excision is both diagnostic and therapeutic.
  
  
  METHODS
  A 49-days old girl presented with nonbilious vomiting of 48 hours of evolution. Infantile hypertrofic pyloric stenosis was suspected. Ultrasound showed a nonobstructive nodular lesion in the anterior pyloric wall. MRI suggested a myofibroblastic tumor. We proceeded to laparotomy and complete resection of the pyloric tumor. Histologic diagnosis was gastric adenomyoma.
  
  
  CONCLUSIONS
  Pyloric adenomyoma causes obstructive symptoms similar to other common entities such as hypertrophic pyloric stenosis or cystic duplication. We have to consider this condition in children with digestive symptoms and radiological images of intussusceptions or duplication. Surgical excision is recommended to reach a definitive diagnosis and to avoid a possible malignant degeneration.
