To be on the safe side, this patient had a biopsy performed and a low power photomicrograph from the specimen shows the typical benign appearance of an enchondroma with chondroid matrix being formed by chondrocytes that have very small pyknotic nuclei. There is nothing here that would suggest the diagnosis of chondrosarcoma.
