Well-differentiated chondrosarcoma of the humerus with prominent granular cell component: a hitherto unreported occurrence.
We report the case of a well-differentiated chondrosarcoma of the proximal humerus in a 60-year-old man that featured a prominent component of granular cells, the granules being shown by electron microscopy to be lysosomal. Although secondary granular cell changes have been described in a large variety of tumor types, this is, to the best of our knowledge, the first documentation of this phenomenon in a skeletal chondrosarcoma.
