Subcutaneous hydatidosis due to iatrogenic spreading of cystic fluid during surgery

Subcutaneous involvement is a rare manifestation of echinococcosis. We report a rare case of a 28-year-old woman with widespread hydatidosis of the lung, liver, and subcutaneous adipose tissue. The patient underwent surgical excision of multiple hepatic and pulmonary cysts with a thoraco-abdominal incision two years earlier. The subcutaneous cyst was located over the incision, and it is likely that resulted from accidental rupture of the primary cyst and spreading of scolices during surgery.
