title: Osteosarcoma of the talus: a case report and review of the literature.
abstract: Osteosarcoma of the talus is extremely rare and only few cases have been reported in the literature. We present a case of a 33 years old male who presented with painful swelling of his left ankle joint. He underwent several radiological diagnostic modalities which showed osteolytic lesion in the posterior aspect of the left talus associated with new bone formation projecting from the posterior-medial aspect of that bone. His chest X-Ray showed multiple rounded lung metastases some of them showed calcifications. Open biopsy was performed. The histopathology confirmed the diagnosis of osteoblastic osteosarcoma of the talus.
