Myxoid liposarcoma is a rare form of soft-tissue sarcoma. Although most patients initially respond well to treatment, approximately 21% relapse, highlighting the need for alternative treatments. To identify novel treatment regimens and gain a better understanding of myxoid liposarcoma tumor biology, we screened various candidate and approved targeted therapeutics and chemotherapeutics against m...

Myxoid soft-tissue sarcomas represent a heterogeneous group of mesenchymal tumors characterized by a predominantly myxoid matrix, including myxoid liposarcoma (MLS), low-grade fibromyxoid sarcoma (LGFMS), extraskeletal myxoid chondrosarcoma (EMC), myxofibrosarcoma, myxoinflammatory fibroblastic sarcoma (MIFS), and myxoid dermatofibrosarcoma protuberans (DFSP). Cytogenetic and molecular genetic ...

The histopathologic features of 10 myxoid adrenocortical neoplasms were analyzed, and epidermal growth factor receptor (EGFR) expression, EGFR gene copy number, and EGFR gene mutations in the 10 tumors were detected by using immunohistochemical analysis, fluorescence in situ hybridization, and the Scorpion Amplification Refractory Mutation System (DxS, Manchester, England), respectively. Histol...

Endometrial stromal sarcoma (ESS) is the second most common malignant uterine mesenchymal tumor. It affects women primarily in the perimenopausal age group. ESSs are morphologically heterogeneous. The distinction between uterine smooth muscle tumors such as cellular leiomyoma and myxoid leiomyosarcoma and low-grade ESS can be problematic when stromal sarcomas show prominent smooth muscle differ...

32 ABSTRACT Benign nerve sheath myxoma (myxoid neurothekeoma) is a rare benign cutaneous neoplasm of nerve sheath origin. This tumor is commonly seen in the head and neck region and sometimes in the upper extremity. The presence of myxoid neurothekeoma on the lower limb is seldom and rarely reported. In this report we presented a new case of myxoid neurothekeoma in the lower limb of a 42-year-o...

We studied the practicality of issuing a cytologic diagnosis of myxoma/juxta-articular myxoid lesion/ganglion (MJG) by reviewing all fine-needle aspiration (FNA) biopsy specimens of soft tissue masses in our files with diagnoses of myxoma, myxoid cyst, myxoid lesion, ganglion, or ganglion cyst. The control group was soft tissue aspirates with abundant myxoid stroma. Of 39 cases with a cytologic...

This report describes a case of congenital dermatofibrosarcoma protuberans (DFSP) with fibrosarcomatous (FS) and myxoid areas. Immunohistochemical results showed that tumour cells in ordinary DFSP areas were diffusely positive for CD34, whereas in the FS and myxoid areas, few tumour cells were positive for this antigen. Ki-67 positive tumour cell numbers were greater in the FS (11.8%) and myxoi...

Myxoid liposarcoma is a subtype of liposarcoma. This specific subtype can be identified based on its characteristic histological and cytogenetical features. The tumor has a fusion transcript of the CHOP and TLS genes, which is caused by t(12;16)(q13;p11). Most of the fusion transcripts that have been identified fall into three categories, specifically type I (exons 7-2), type II (exons 5-2), an...

Chondrosarcoma of the bone is second most common malignant bone tumor next only to osteosarcoma. The most common type of chondrosarcoma is the conventional chondrosarcoma (90%). The myxoid variant is a rare occurrence and is associated with a worse outcome as opposed to conventional type. There are only a few references of this tumor in literature. The most common location for skeletal myxoid c...

BACKGROUND Extraskeletal myxoid chondrosarcoma is a unique and distinct clinicopathological entity in terms of its origin, morphology, and biologic behavior. Despite being a slow-growing tumor, it has a high rate of local recurrences and history of metastases to uncommon sites like the mandible, liver, retroperitoneum, right ventricle, pancreas, and central nervous system. Here, we report a ver...
