A 25-year-old man reported with swelling in the right lower jaw since five months. Clinically, a diffuse swelling Swelling on the posterior part of the mandible, right side measuring of mandible measuring 6 Χ 5 cm 2 was noted. It was hard in consistency, with bicortical expansion. No scars or sinus discharge was present. Intraorally, obliteration of buccal vestibule and lingual cortical expansion were present. The swelling was tender, with no sign of paraesthesia. No intraoral discharge was present. Radiologically, the lesion had moth-eaten appearance, with mixed radiolucency.


Numerous large irregular blood-filled channels (sinusoids) supported by connective tissue septae containing multinucleated giant cells and primitive-looking mesenchymal cells [Figure 1],[Figure 2],[Figure 3],[Figure 4],[Figure 5],[Figure 6].{Figure 1}{Figure 2}{Figure 3}{Figure 4}{Figure 5}{Figure 6}Sinusoidal spaces partially lined by endothelial cells cells and containing extravasated RBCs.Highly pleomorphic and hyperchromatic mesenchymal cells resembling atypical osteoblasts were seen throughout the section [Figure 7],[Figure 8],[Figure 9],[Figure 10],[Figure 11],[Figure 12],[Figure 13],[Figure 14].{Figure 7}{Figure 8}{Figure 9}{Figure 10}{Figure 11}{Figure 12}{Figure 13}{Figure 14}Osteoid formation and dystrophic calcifications were noted.

 Differential Diagnosis

Aneurysmal bone cyst has thin rims with well-defined inner margins and septae surrounding the large blood-filled vascular spaces.

Conventional osteosarcoma shows tumor cells which are capable of producing extracellular matrix that may be osseous, cartilaginous or fibrous in various proportions with production of osteoid.

 Final Diagnosis

Telangiectatic osteosarcoma
