title: Non-neoplastic soft tissue masses that mimic sarcoma.
abstract: Non-neoplastic soft tissue masses may mimic soft tissue sarcoma in a wide variety of clinical settings. Systematic and thorough review of patient history, physical examination, imaging, laboratory results, and biopsy will allow the clinician to differentiate between the two in most cases. We describe several common non-neoplastic entities that may mimic soft tissue sarcoma in case presentation format along with the characteristics that help distinguish them.
