title: Primary extraskeletal myxoid chondrosarcoma of pulmonary arteries: a rare mimic of acute pulmonary thromboembolism.
abstract: Primary extraskeletal myxoid chondrosarcoma of the pulmonary arteries is a very rare entity. Multimodality imaging reports on this entity are few. Myxoid chondrosarcoma is characterized by chondroid and neurogenic differentiation in extraskeletal locations. These tumours represent fewer than 2.5% of all soft-tissue sarcomas, and are most commonly found in the lower extremities, limb girdles, distal extremities and trunk. We report an unusual case of a 31-year old man with histopathologically proven extraskeletal myxoid chondrosarcoma of the pulmonary arteries mimicking acute pulmonary thromboembolism.
