A case of parachordoma on the chest wall and literature review

Abstract

Parachordoma is an extremely uncommon soft-tissue tumor, which mainly occurs in the deep soft-tissue of the distal parts of the limbs, such as deep fascia, muscle tendon, synovial or soft-tissue closed to the bone. Nevertheless, the literature reports about parachordoma on the thoracic wall were scarce. The clinical and imaging manifestation has a non-specific appearance. In this article, we reported one case of parachordoma of the thoracic wall that we met in clinical works and reviewed the literature.

Incidental findings in and around the prostate on prostate MRI: a pictorial review

“…Parachordoma is a rare, low-grade malignant musculoskeletal soft tissue tumour which resembles extra-skeletal myxoid chondrosarcoma and chordoma but away from the craniospinal axis [ 26 ]. It mainly develops in the deep soft tissue of the distal parts of the limbs, adjacent to deep fascia, tendon, synovium and osseous structures in extremities.…”

“…It mainly develops in the deep soft tissue of the distal parts of the limbs, adjacent to deep fascia, tendon, synovium and osseous structures in extremities. It forms a circumscribed firm tumour, with a variety of histological patterns and cytological features, including cords and nests of cells, some of which are vacuolated [ 26 ]. Histologically, they show scattered, large, clear, multi-vacuolated cells (physaliferous cells) and on immunohistochemistry, they are positive for cytokeratin and S-100 protein [ 27 ].…”
