Detection of CSF1 rearrangements deleting the 3' UTR in tenosynovial giant cell tumors.

Genes Chromosomes Cancer 2020 02 12;59(2):96-105. Epub 2019 Sep 12.

Department of Pathology and Laboratory Medicine, Mount Sinai Hospital, Toronto, Ontario, Canada.

Tenosynovial giant cell tumors (TGCTs) are characterized by rearrangements of CSF1, thought to drive overexpression of macrophage colony-stimulating factor (CSF1), thereby promoting tumor growth and recruitment of non-neoplastic mononuclear and multinucleated inflammatory cells. While fusions to collagen promoters have been described, the mechanism of CSF1 overexpression has been unclear in a majority of cases. Two cohorts of TGCT were investigated for CSF1 rearrangements using fluorescence in situ hybridization (FISH) and either RNA-seq or DNA-seq with Sanger validation. Read More

Histologically benign metastasizing tenosynovial giant cell tumor mimicking metastatic malignancy: A case report and review of literature.

Radiol Case Rep 2019 Aug 24;14(8):934-940. Epub 2019 May 24.

University of Illinois College of Medicine, 1740 W. Taylor St., MC 931, Chicago, IL, 60612, USA.

Diffuse-type tenosynovial giant cell tumor (D-TGCT), otherwise known as pigmented villonodular synovitis, is a locally aggressive tumor which can show multiple recurrences but is rarely associated with metastasis. A handful of studies have elucidated the imaging features and clinical course in metastatic D-TGCT with malignant transformation on histology. However, only 5 cases of metastatic D-TGCT with benign histological features have been reported in the literature, with the clinical course and prognosis reported in only 1 case. Read More

Expression Profiling of Receptor-Activator of Nuclear Factor-Kappa B Ligand in Soft Tissue Tumors.

Tohoku J Exp Med 2019 06;248(2):87-97

Division of Orthopedic Surgery, Niigata University Graduate School of Medical and Dental Sciences.

Bone and soft tissue tumors are derived from mesenchymal cells, and they are hard to treat. Receptor-activator of nuclear factor-kappa B ligand (RANKL) is an essential cytokine for osteoclast differentiation and activation and is expressed on the surface of osteoblasts or stromal cells. In this study, to explore the potential of denosumab treatment for soft tissue tumors, we analyzed the expression profiles of RANKL mRNA in 425 tumor specimens of 33 histological types by real-time RT-PCR.

Surgical outcomes of patients with diffuse-type tenosynovial giant-cell tumours: an international, retrospective, cohort study.

Lancet Oncol 2019 06 24;20(6):877-886. Epub 2019 Apr 24.

Department of Orthopaedics, Leiden University Medical Center, Leiden, Netherlands.

Background: Diffuse-type tenosynovial giant-cell tumour is a rare, locally aggressive, and difficult-to-treat soft tissue tumour. Clinical and surgical outcomes depend on multiple factors, including preoperative diagnostic assessment, the localisation and extent of disease, and possibly the choice of treatment modalities by orthopaedic surgeons. We did a retrospective cohort study to characterise global surgical treatment protocols, and assess surgical outcomes, complications, and functional results in patients with diffuse-type tenosynovial giant-cell tumours.

Osteochondral Lesion in Diffuse Pigmented Villonodular Synovitis of the Knee.

Knee Surg Relat Res 2019 Mar;31(1):67-71

Department of Orthopaedic Surgery, The Orthopaedic Speciality Clinic, Pune.

Pigmented villonodular synovitis (PVNS) is a rare benign condition that is locally aggressive and may destructively invade the surrounding soft tissues and bone causing functional loss of the joint and the limb. The knee is the most affected joint (range, 28% to 70%) but involvement of the bone is not a common feature seen at this site. We present a rare case of diffuse PVNS of the knee associated with subchondral cyst of the lateral femoral condyle. Read More
