Key result
Bedside ultrasound detects a large undifferentiated pleomorphic thigh sarcoma, facilitating prompt surgical resection.
Why the study?
Undifferentiated pleomorphic sarcomas are aggressive and enlarge rapidly with high metastatic risk, making prompt diagnosis imperative.
Case Report (n=1)
Bedside ultrasound can be utilized for the initial evaluation of aggressive soft tissue tumors like undifferentiated pleomorphic sarcoma.
May support bedside ultrasound for initial soft tissue sarcoma evaluation; leaves open validation in prospective studies.
Soft tissue sarcomas arise infrequently and make up less than 1% of all cancers. An undifferentiated pleomorphic sarcoma (UPS), formerly known as a malignant fibrous histiocytoma, is a malignant subtype of soft tissue sarcoma identified by a lack of specific immunohistochemical markers for lineage differentiation. These tumors are aggressive and enlarge rapidly with an increased risk of metastasis, thus prompt diagnosis, treatment, and post-resection surveillance are imperative. This case report demonstrates an incidental finding of a large undifferentiated pleomorphic sarcoma of the posterior thigh in an 86-year-old male initially evaluated with a bedside ultrasound.

Gencarelli et al. (2022) conducted a case report in Undifferentiated Pleomorphic Sarcoma (n=1). Bedside ultrasound and surgical resection was evaluated. A bedside ultrasound successfully identified a 16.0 × 8.1 × 9.5 cm undifferentiated pleomorphic sarcoma in the posterior thigh of an 86-year-old male, facilitating prompt surgical resection.
