Abstract

Pleomorphic hyalinizing angiectatic tumor (PHAT) is a rare soft tissue tumor of low malignant potential, which most often arises in the lower extremities. To the best of our knowledge, there have been no prior descriptions of the imaging features of this neoplasm. In this case series, we report the imaging findings in three patients. Two patients had a lower extremity subcutaneous PHAT, while the third patient had an intramuscular upper extremity PHAT. While imaging features are variable, a diagnosis of PHAT should be considered when encountering an enhancing, subcutaneous tumor with ill-defined margins, particularly in the extremity.
