Primary subcutaneous hydatid cyst on the incisional scar following open cholecystectomy: a rare case report and review of the literature

Abstract

Aims: Primary subcutaneous hydatid cyst (pSHC) in the abdominal wall is very seldom clinical presentation, even in endemic area including Turkey. Herein we present a new case of pSHC on incision scar of abdominal wall following cholecystectomy, which is the first in the literature.

Materials and methods: We conducted a case presentation and a literature review of studies published in the medical literature on pSHC of the anterior abdominal wall, accessed via PubMed, Medline, and the Google Scholar databases. Keywords used were hydatidosis, echinococcosis, hydatid disease, subcutaneous, abdominal wall, and soft tissue.

Case presentation: A 57-year-old female patient applied to emergency department with complaint of abdominal pain and swelling on right upper quadrant of abdominal wall. She Underwent cholecystectomy with right subcostal incision 9 years ago. The patient was hospitalized in the General Surgery Clinic. Radiological findings revealed a lesion resembling a hydatid cyst. Prior to surgery, patient was treated with albendazole for 10 days. Cystic lesion was completely excised under the local anesthesia without cyst. rupture. Macroscopic and microscopic examination of the specimens confirmed hydatid cysts. No recurrence had occurred after 9 months of follow up.

Conclusion: pSHC in the abdominal wall should be well-considered in the differential diagnosis of every subcutaneous cystic mass, especially in countries endemic for hydatidosis. In order to avoid complications such as anaphylaxis and cyst spillage, the best surgical approach should be the total excision of the cyst without opening the cyst cavity.
