This is a 65-years old lady who had a swelling over the middle phalanx of her finger for many years. It started paining a month prior following an injury.
The radiographs and CT scan show a clear fracture through a lesion that is characteristic of an enchondroma, even though a chondroid matrix is not seen on the CT scan. The patient and surgeon insisted on a biopsy to prove that this is a benign chondroid lesion.
Like the renal tumor earlier, sometimes, it is best not to argue, so we went ahead and did the biopsy using an 18G coaxial biopsy gun and proved that it indeed was a benign enchondroma. And everyone was happy and relieved.
