Abstract:
Low-grade fibromyxoid sarcoma, also known as Evans tumor, is a low-grade sarcoma that most commonly arises in the deep soft tissue of the proximal extremities or trunk in young adults. It is very rare in the viscera as a primary site, with only a few cases reported in the literature. Here, we present a case of Evans tumor occurring in an unusual and rarely reported location; an intrathoracic mass arising from the diaphragmatic pleura.
