dermatofibrosarcoma/histone

Dermatofibrosarcoma protuberans (DFSP) is the most common dermal sarcoma; it is characterized by the presence of the COL1A1-PDGFB translocation, which causes the constitutive activation of the platelet-derived growth factor β (PDGFB) signaling pathway. DFSP frequently exhibits local recurrence and

The diagnosis of malignant peripheral nerve sheath tumors can be challenging and other spindle cell sarcomas commonly enter in the differential diagnosis. Loss of trimethylation at lysine 27 of histone-H3 (H3K27me3) by immunohistochemistry was recently described in malignant peripheral nerve sheath

Sarcomas are mesenchymal cancers, which, in many cases, have distinctive molecular features. Limb-sparing surgery delivered at specialised sarcoma centres as part of a multidisciplinary approach has become the standard treatment for most patients and usually provides excellent local control.

A wide variety of cytogenetic abnormalities and molecular pathways have been implicated in the pathogenesis of sarcoma, and significant progress has been made in the past decade toward identifying potential therapeutic targets. However, apart from gastrointestinal stromal tumors (GISTs) and

The diagnosis of malignant peripheral nerve sheath tumor is challenging, particularly in the sporadic setting. Inactivation of the polycomb repressive complex 2 (PRC2), resulting from inactivating mutations of its constituents SUZ12 or EED1, has recently been identified in 70-90% of malignant

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive sarcomas that can show overlapping features with benign neurofibromas as well as high-grade sarcomas. Additional diagnostic markers are needed to aid in this often challenging differential diagnosis. Recently mutations in two critical
