Primary Soft Tissue Hydatid Cysts.

OBJECTIVE

Hydatid cyst disease is a helminthic infection caused by Echinococcus granulous, which is encountered with cysts in many organs, especially the liver and lungs. Soft tissue and intramuscular hydatid cyst are rare even in endemic countries. It is challengig to distinguish subcutaneous and intramuscular hydatid cysts from soft tissue tumors. This study aimed to present the clinical features of primary soft tissue hydatid cyst cases without liver and lung hydatid cyst in the Southeast Anatolian region, where hydatid cyst disease is endemic.

METHODS

Patients admitted to the Şanlıurfa Training and Research Hospital General Surgery and Orthopedics and Traumatology Outpatient Clinic between September 2018 and December 2019 with complaints of pain and/or swelling under the skin and soft tissue were evaluated. After the examinations, the records of the patients who were operated on with a pre-diagnosis of hydatid cyst and whose histopathologic evaluation was reported as a hydatid cyst were reviewed retrospectively.

RESULTS

Eight patients were included in the study. The mean age of the patients was 39.75±14.80 years. Lesions were located in neck (12.5%), left thoracic posterior area (25%), gluteus (25%), thigh (12.5%), right upper quadrant of abdominal wall (12.5%), and under the right clavicle (12.5%). When imaging methods were examined, ultrasonography was performed in 7 patients (87.5%), chest computed tomography was performed in 1 patient (12.5%), and magnetic resonance imaging was performed in 2 patients (25%).

CONCLUSION

Diagnosis of hydatid cyst should be considered in the differential diagnosis of soft tissue tumors in countries of endemic regions for hydatid cyst disease such as Southeastern Anatolia Region, Turkey.
