Abstract
Examination of the surface of bones (from which soft tissues have been removed) provides a window complementary to that provided by clinical, standard anatomic, laboratory and radiologic studies. That approach, utilized successfully for analysis of other forms of osteosarcoma is applied to the high grade telangiectatic version of medullary osteosarcoma. Examining the surface of afflicted bones overcomes the limited resolution of standard radiologic techniques Herein, the character of bone surface of the telangiectatic variety, previously only theorized in a skeleton from an archeologic sites and subject to isolated veterinary reports, is categorized in an individual with documented disease.
A previously healthy 29 year old Swiss Caucasian male presented with swelling at the lateral aspect of the leg, just proximal to the ankle. Radiological examination revealed cortical breakthrough and slight focal periosteal reaction, associated with severe cortical thinning and an irregular medullary region with subtle cystic areas. This contrasts with other forms of osteosarcoma which grow around residual cortex rather than producing a thin rim.
