Introduction:
Hydatid cyst (HC) disease is a serious health problem in endemic areas, solitary primary subcutaneous hydatid cyst is not frequent and the only symptom is generally a silent growing mass. Total excision remains the mainstay of treatment. The aim of the study was to present a case surgically treated.
Case presentation:
48-year-old female farmer presented with HC of the right hypochondrium who was managed surgically.
Discussion:
The mechanism of primary subcutaneous localization is unclear. There are two potential mechanisms; (a) direct subcutaneous contamination through an injured skin or (b) subcutaneous colonization of ingested eggs after passing liver and lungs. I believe that subcutaneous colonization of the parasite in the circulation after ingestion is an only reliable mechanism than the other contact theory, because of the cases in literature occur without any direct contamination.
Conclusion:
Primary subcutaneous hydatid cyst must always be considered in the differential diagnosis of silent growing mass in soft tissues or subcutaneous. History and physically associated with ultrasound and magnetic resonance imaging are sufficient to achieve a correct preoperative diagnosis.
