title: Complete hysteroscopic resection of a large atypical polypoid adenomyoma, followed by a successful pregnancy.
abstract: OBJECTIVE
  To describe the hysteroscopic resection of a large atypical polypoid adenomyoma (APA) in a young patient followed by a successful pregnancy.
  
  
  METHODS
  Case report.
  
  
  METHODS
  Department of Obstetrics and Gynecology, Niigata University Medical and Dental Hospital, Niigata, Japan.
  
  
  METHODS
  A 29-year-old female who had an endocervical tumor 4 cm in size and a diagnosis of APA.
  
  
  METHODS
  Conservative hysteroscopic resection of the lesion.
  
  
  METHODS
  Disease and pregnancy outcome.
  
  
  RESULTS
  The lesion was completely resected by a pathologically guided, hysteroscopic surgery. The patient spontaneously became pregnant and gave birth by vaginal delivery and is free from disease 3 years after the surgery.
  
  
  CONCLUSIONS
  Conservative hysteroscopic surgery may be a good treatment option for APA in patients who wish to preserve their fertility, even for patients with a large lesion.
