Extraskeletal chondroma with lipoblast-like cells.
An extraskeletal chondroma occurring over the dorsum of the wrist of a 61-year-old woman is reported. The lobulated tumor is cellular and shows mild-to-moderate nuclear pleomorphism of the chondroid cells. A unique feature is that some tumor cells are univacuolated and multivacuolated owing to accumulation of lipid, mimicking the appearances of lipoblasts.
