title: Hydatid disease presenting as cutaneous fistula: review of a rare clinical presentation.
abstract: Hydatid disease has a worldwide distribution as a result of more global travel. Liver and lungs are the most common sites for the primary hydatid cysts in the human body. We managed a 68-year-old man who presented with abdominal distension and umbilical fistula, discharging daughter cysts. Ultrasound imaging of the abdomen showed hepatic hydatid cyst forming a fistula at the umbilicus. The patient underwent a laparotomy with partial cystectomy and excision of the fistula tract. The umbilicus healed after the procedure. The patient did not have any recurrences in 5 years of follow-up. Spontaneous cutaneous fistulization of liver hydatid cyst is a rare presentation. A detailed literature search revealed 15 cases published in all languages. Hydatid disease presenting as an umbilical fistula has not been reported yet. We summarize all these cases including the presentation, findings, management, and outcome. Combined surgical and medical treatment is successful in healing of hepatic hydatid cutaneous fistula.
