title: Atypical Presentation of Hydatid Cyst in the Thigh.
abstract: To emphasise that hydatid cyst disease can present as a soft tissue mass even in an unusual site like the thigh, we report the case of a 21-year male patient who presented to Surgical Unit IV, Civil Hospital, Karachi, with a slow growing cystic swelling on the medial aspect of the left thigh. Based on serology and imaging, a diagnosis of solitary subcutaneous hydatid cyst thigh was made and cystopericystectomy was performed. Histopathology confirmed the diagnosis. Up to three months postoperatively, there was no recurrence. In the absence of visceral organ involvement, this is the first reported case of primary subcutaneous hydatid disease of the thigh in Pakistan.
