Technetium-99m DTPA Uptake in an Extra-Skeletal Myxoid Chondrosarcoma: Case Report

Abstract

Extra-skeletal myxoid chondrosarcoma (ESMC) is quite rare and was first described by Stout in 1953 (1,2). We describe a case of ESMC in which an abnormal accumulation of technetium-99m (^99mTc) DTPA was detected in the area of the ESMC prior to eventual diagnosis. Recognition of ^99mTc-DTPA uptake in ESMC may be of value in early diagnosis, and ^99mTc-DTPA activity outside the urogenital tract can be an early sign of a hypervascular tumor and should not be dismissed.
