New cards

Squamous Cell Carcinoma

patient's radiograph shows, ill-defined, radiolucency on anterior mandible. Teeth appear to be "floating" due to bone destruction. PDL spaces of those roots are widened. What is the diagnosis?

Squamous Cell Carcinoma

patient's radiograph shows, defined radiolucent lesion on the posterior mandible. IAN canal appears destroyed. Posterior teeth appear to be "floating" due to bone destruction.There is sudden mobility of #30, 31 for 1 month. There is no clinical evidence of peridontal disease. Patient experiences a dull ache. What is the diangosis?

Osteosarcoma

patient's radiograph shows the following:

•Garrington sign (widened PDL space)

•Ragged, ill-defined radiolucent/paque mixed area

•'sun ray' periosteal reaction

- spiked root resorption pattern
