[Juxtacortical chondroma in the thenar region]

Abstract

Juxtacortical chondromas represent a special type of chondroma which, when in a parosteal position, have a pedicle on the bone or periosteum. These benign tumours are not specific to any age group or sex. Typical radiological findings are the combination of calcification and adjacent soft tussue vesicles, as well as a rarefaction and sclerosis of the cortex of the adjacent bones. The only successful therapy is complete exstirpation. The case of a 56-year-old female patient with a juxta-cortical chondroma in the thenar region is discussed.
