Telangiectatic osteosarcoma of the radius

A missed diagnosis case report.

Abstract

Telangiectatic osteosarcoma is a rare variant of osteosarcoma accounting for 3%-11% of all primary osteosarcomas.¹ It has well described distinctive radio-pathological features. Radiographically, these tumours appear as purely lytic destructive lesions located in the metaphyses of long bones. On gross clinical examination, it presents as a soft and cystic mass.

Histologically findings are that of aneurysmally dilated spaces lined by osteoid-producing atypical stromal cells. This is a report on a patient with an atypical telangiectatic osteosarcoma which was missed by the primary treating medical team.
