ES in the groin area may be easily misdiagnosed with undifferentiated pleomorphic sarcoma, leiomyosarcoma, rhabdomyosarcoma, and other mesenchymal tumors. Herein, we reported a single case of a patient with proximal-type epithelioid sarcoma of the groin, including its clinical and imaging findings. We also discussed some previously reported similar cases. </span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:#1f497d"><span style="font-style:italic"><span style="font-weight:bold"><span style="language:en-US">Case Presentation</span></span></span></span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="color:#1f497d"><span style="font-weight:bold"><span style="language:en-US">:</span></span></span></span></span> <span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="language:en-US">Our ES patient was</span></span></span><span lang="en-US" style="font-size:9.0pt"><span style="font-family:Calibri"><span style="language:en-US"> a 24-year-old male who developed a subcutaneous nodule in the groin area 1 year before admission.

Surgery seems to be the most effective treatment for ES. The effectiveness of auxiliary and radiotherapy needs to be confirmed by a large amount of data. A systematic understanding of the clinical and imaging features of ES in the groin area may help clinical and imaging doctors to correctly diagnose the disease.</span></span></span></div> Epithelioid sarcoma, groin, mesenchymal tumor, case report. 887 892 http://ijrr.com/browse.php?a_code=A-10-1-995&slc_lang=other&sid=1 X.
