Extraskeletal myxoid chondrosarcoma: A report of two cases GUO‑WEI ZHANG, AI‑JIE WANG, GUANG‑HUI ZHANG, SHAN‑NA ZHAO and JIAN‑LI QU CT/MR Room, Yantaishan Hospital, Yantai, Shandong 264001, P.R. China Received June 28, 2013; Accepted January 7, 2014 DOI: 10.3892/ol.2014.1884 Abstract. Extraskeletal myxoid chondrosarcoma (EMC) is a relatively rare but well‑defined neoplasm. This report describes two pa­tients, one with EMC of the buttock and one with EMC of the knee. The two cases presented with large lobed masses and long T1 and T2 signaling identified by magnetic resonance imaging (MRI). An enhanced MRI scan demonstrated enhancement of the tumors. The tumors were composed of strands or cords of oval and spindle cells embedded in abundant myxoid stroma. Pathology results confirmed EMC. Introduction Extraskeletal chondrosarcomas were first described by Stout and Verner in 1953 (1); however, it was not until 1972 that extraskeletal myxoid chondrosarcoma (EMC) was histopathologically defined as its own entity (2). EMC is provisionally classified as a tumor of uncertain differentiation in the revised version of the World Health Organization classification of tumors of soft tissue and bone in 2002 (3). EMC is a relatively rare but well‑characterized tumor that accounts for

Extraskeletal myxoid chondrosarcoma of the thigh in a child: a case report.
Extraskeletal myxoid chondrosarcoma (EMC) is aggressive in children. The condition in children differs to that in adults and to skeletal myxoid chondrosarcoma. We report on a 9-year-old girl with EMC in her left thigh. She underwent above-knee amputa

The extraskeletal myxoid chondrosarcoma (CME) is a rare malignant soft tissue tumour described as a distinct clinical, histological, immunohistochemical, genetical and evolutive entity. It represents only 2.5% of soft tissue sarcomas. Its individuali

Extraskeletal myxoid chondrosarcoma arising in the femoral vein: a case report.
Soft tissue tumors arising in deep veins of the extremities are uncommon, although a few cases of synovial sarcoma or leiomyosarcoma arising in the femoral vein have been documented. However, to the best of our knowledge, an extraskeletal myxoid chon

Extraskeletal myxoid chondrosarcoma of the vulva with PLAG1 gene activation: molecular genetic characterization of 2 cases.
Extraskeletal myxoid chondrosarcoma (EMC) is a rare mesenchymal neoplasm, rarely reported in the genitourinary tract with only 5 cases reported in the vulva. We investigated 2 cases of vulvar sarcomas whose morphologic appearance and immunohistochemi

Primary extraskeletal myxoid chondrosarcoma of pulmonary arteries: a rare mimic of acute pulmonary thromboembolism.
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 loc

Results of sub-analysis of a phase 2 study on trabectedin treatment for extraskeletal myxoid chondrosarcoma and mesenchymal chondrosarcoma.
Trabectedin is reported to be particularly effective against translocation-related sarcoma. Recently, a randomized phase 2 study in patients with translocation-related sarcomas unresponsive or intolerable to standard chemotherapy was conducted, which
