title: Endometriosis presenting as an acute groin swelling: a case report.
abstract: BACKGROUND
  Many conditions present as groin swellings, in both the elective and emergency setting. The management of these conditions varies widely, thus a prompt and accurate diagnosis is important.
  
  
  METHODS
  A 27 year old female presented with an acute painful swelling in her right groin. A preliminary diagnosis of an incarcerated femoral hernia led to urgent surgical exploration. Histology of the excised tissue showed appearances consistent with endometriosis.
  
  
  CONCLUSIONS
  Endometriosis is an unusual cause of an acute groin mass, which should be considered as a differential diagnosis in women of childbearing age.
