Case report: Telangietactic osteosarcoma in a 20 year old male

T
elangiectatic osteosarcoma (TO) is one of the rare
subtypes of osteosarcoma (OS) and accounts for less
than 4% of all tumors in the appendicular
skeleton.TOis a
rare variant of OS with distinctive radiographic, gross, and
microscopic features and prognostic implications. Although
conventional OSs may contain telangiectatic elements,
only those composed almost entirely of telangiectatic
tissue are generally considered true examples of this entity.
We present the case of a 20-year-old male patient who
consulted for wrist pain. An X-ray showed a lytic destructive
lesion of the distal left radius while magnetic resonance
imaging revealed features highly suggestive of telangiectatic
osteosarcoma. The lesion was biopsied which confirmed
osteosarcoma, with difficulty subtyping due to the limited
material available. After four cycles of chemotherapy the
patient underwent an elbow disarticulation. The specimen
was sent to pathology where gross examination showed
cystic lesion filled with blood of the of the distal radial
metaphysis. Histological examination showed that the
lesion is composed largely of hemorrhage and necrotic
debris. Blood pools do not demonstrate an endothelial
lining. Within these blood lakes, variously sized septa are
identified, which contain atypical stromal cells with nuclear
hyperchromasia, atypical mitoses, and pleomorphism.
Telangiectatic osteosarcoma is a rare variant, representing
around 3% of osteosarcomas overall. The main differential
radiographically, grossly and on histology is with aneurysmal
