Lower Limb Myxofibrosarcoma Presenting as a Pulmonary Tumour Embolism: A Case Report.

Pulmonary tumour embolism is a rare complication of malignancy and should be considered a differential diagnosis if imaging features are atypical for a bland thrombus. It can arise from a range of primary tumours, including soft tissue sarcomas; however, reported cases are sparse. We present a case of pulmonary tumour embolism secondary to a large right knee myxofibrosarcoma, with diagnosis confirmed following biopsy of a pulmonary nodule and a palpable inguinal lymph node.
