title: A primary subcutaneous hydatid cyst in the thigh A case report.
abstract: OBJECTIVE
  Hydatid disease is a parasitic disease considered endemic in many parts of the world such as South America, Middle East, Africa, Australia and the Mediterranean regions. Liver and lung hydatid disease accounts for 90% of all echinococcal cysts. Primary hydatid disease of subcutaneous sites is rare and the subcutaneous localization of a solitary hydatid cyst accounts for 1.6%. Not enough data exist for this localization, and only many heterogeneous data are described in order to define this rare condition.
  
  
  METHODS
  We present the case of a 68-year-old-woman affected by a mass in upper-medial side of her right thigh with a 12-year-growing history. Anamnestic data were accurately collected. Many different radiological and specific serum tests were performed in order to define the diagnosis. Surgical approach was decided in order to excide the mass, and a 6-months follow-up was performed.
  
  
  CONCLUSIONS
  Hydatid disease is common in endemic area but uncommon localizations, as in subcutaneous tissues, are a rare condition. Scientific Community lacks of complete and homogeneous data about the approach to this manifestation of the disease. Would be useful a complete review of the literature in order to plan guide-lines for the treatment of uncommon localization.
