title: Mammary myofibroblastoma in the right lateral abdominal wall.
abstract: BACKGROUND
  A mammary-type myofibroblastoma is a rare soft tumor; extramammary myofibroblastomas are especially rare.
  
  
  METHODS
  A 51-year-old woman presented to our department for evaluation of a mass on the right lower abdominal wall. The mass was then excised completely. Gross examination showed a huge, well-circumscribed soft tissue mass. The pathologic diagnosis was an extramammary myofibroblastoma. There was no recurrence after excision at the 6-month follow-up visit.
  
  
  CONCLUSIONS
  A mammary-type myofibroblastoma is a benign soft tissue neoplasm. No malignant behavior and/or recurrence of mammary-type myofibroblastomas after surgical resection have been described as a function of size and location. The present case aimed to provide a possible differential diagnosis for such abdominal masses.
