Imaging Characteristics of Tenosynovial and Bursal Chondromatosis( Book )

1 edition published in 2010 in English and held by 1 WorldCat member library worldwide

Objectives: Our purpose was to identify imaging characteristics of tenosynovial and bursal chondromatosis. Materials and methods: We retrospectively reviewed 25 pathologically confirmed cases of tenosynovial (n=21) or bursal chondromatosis (n=4). Patient demographics and clinical presentation were reviewed. Imaging was evaluated by two musculoskeletal radiologists with agreement by consensus, including radiography (n=21), bone scintigraphy (n=1), angiography (n=1), ultrasonography (n=1), CT (n=8), and MR (n=8). Imaging was evaluated for lesion location/shape, presence/number of calcifications, evidence of bone involvement, and intrinsic characteristics on ultrasonography/CT/MR. Results Average patient age was 44 years (range 7 to 75 years) with a mild male predilection (56%). A slowly increasing soft tissue mass was the most common clinical presentation (53%). Lesion locations included the foot (n=8), hand (n=6), shoulder (n=3) knee (n=2), ankle (n=2) and one each in the upper arm forearm, wrist, and cervical spine. All lesions were located in a known tenosynovial (21 cases, 84%) or bursal (four cases, 16%) location. All cases of bursal chondromatosis were round/oval in shape. Tenosynovial lesions were fusiform (65%) or round/oval (35%). Radiographs commonly showed a soft tissue mass (86%) and calcification (90%). Calcifications were predominantly chondroid (79%) or osteoid (11%) in character with>10 calcified bodies in 48%. CT detected calcifications in all cases. The intrinsic characteristics of the nonmineralized component showed low attenuation on CT (75%), high signal intensity on T2-weighted MR (76%) and a peripheral/ septal contrast enhancement pattern (100%). Conclusions Imaging of tenosynovial and bursal chondromatosis is often characteristic with identification of multiple osteochondral calcifications (90% by radiographs; 100% by CT)
Sox10—A Marker for Not Only Schwannian and Melanocytic Neoplasms But Also Myoepithelial Cell Tumors of Soft Tissue( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

Abstract : Sox10 transcription factor is expressed in schwannian and melanocytic lineages and is important in their development and can be used as a marker for corresponding tumors. In addition, it has been reported in subsets of myoepithelial/basal cell epithelial neoplasms, but its expression remains incompletely characterized. In this study, we examined Sox10 expression in 5134 human neoplasms spanning a wide spectrum of neuroectodermal, mesenchymal, lymphoid, and epithelial tumors. A new rabbit monoclonal antibody (clone EP268) and Leica Bond Max automation were used on multitumor block libraries containing 30 to 70 cases per slide. Sox10 was consistently expressed in benign Schwann cell tumors of soft tissue and the gastrointestinal tract and in metastatic melanoma and was variably present in malignant peripheral nerve sheath tumors. In contrast, Sox10 was absent in many potential mimics of nerve sheath tumors such as cellular neurothekeoma, meningioma, gastrointestinal stromal tumors, perivascular epithelioid cell tumor and a variety of fibroblastic-myofibroblastic tumors. Sox10 was virtually absent in mesenchymal tumors but occasionally seen in alveolar rhabdomyosarcoma. In epithelial tumors of soft tissue, Sox10 was expressed only in myoepitheliomas, although often absent in malignant variants. Carcinomas, other than basal cell–type breast cancers, were only rarely positive but included 6% of squamous carcinomas of head and neck and 7% of pulmonary small cell carcinomas. Furthermore, Sox10 was often focally expressed in embryonal carcinoma reflecting a primitive Sox10-positive phenotype or neuroectodermal differentiation. Expression of Sox10 in entrapped non-neoplastic Schwann cells or melanocytes in various neoplasms has to be considered in diagnosing Sox10-positive tumors. The Sox10 antibody belongs in a modern immunohistochemical panel for the diagnosis of soft tissue and epithelial tumors. Abstract : Supplemental Digital Content is available in the text
