title: Reconstruction with bilateral gluteus maximus myocutaneous rotation flap after wide local excision for perianal extramammary Paget's disease. Report of two cases.
abstract: OBJECTIVE
  Extramammary Paget's disease is a rare dermatosis. Wide local excision is recommended in patients with perianal extramammary Paget's disease. After wide local excision, it is necessary to do reconstruction, with preservation of bowel function. We present here two cases of perianal Paget's disease, in which the patients were treated by reconstruction with bilateral gluteus maximus myocutaneous rotation flap after wide local excision.
  
  
  METHODS
  A 55-year-old woman and 58-year-old man were admitted with anal pain and bleeding. Histologic examination of the perianal lesion revealed the presence of typical Paget's cells, and no underlying carcinoma and no distant metastasis was detected in either patient. Wide local excision, including the rectal mucosa, was performed, with reference to intraoperative frozen sections. Surgical defect was overlapped with bilateral gluteus maximus myocutaneous rotation flap, and the anus was reconstructed.
  
  
  RESULTS
  Postoperative bowel function and quality of life were well preserved, and flaps healed satisfactorily. Patients have had no recurrence and have been able to return to work.
  
  
  CONCLUSIONS
  Bilateral gluteus maximus rotation flap may be useful after wide local excision of perianal extramammary Paget's disease without underlying invasive carcinoma.
