Multifocal Cytokeratin Expression in a Dedifferentiated Solitary Fibrous Tumor With Heterologous Rhabdomyosarcomatous Differentiation: A Challenging Diagnosis!

We report the case of a dedifferentiated solitary fibrous tumor with heterologous rhabdomyosarcomatous differentiation in a 74-year-old male presenting with a rapidly growing, large soft tissue tumoral mass in the gluteal muscles of the right hip. Dedifferentiation in solitary fibrous tumor had not been recognized until very recently and is an extremely rare phenomenon in this tumor type. In the present case, the diagnosis of dedifferentiated solitary fibrous tumor was difficult because of the absence of areas of conventional solitary fibrous tumor with a predominantly poorly differentiated, anaplastic tumor component in the incision biopsy composed of heterogeneous areas with small blue round cell (Ewing sarcoma-like), rhabdoid, epithelioid, and pleomorphic morphology.

Intraorganizational Communication and Job Satisfaction Among Flemish Hospital Nurses: An Exploratory Multicenter Study.

Intraorganizational communication affects job satisfaction and turnover. The goal of this study was to explore relationships between communication and job satisfaction, intention to leave, and burnout among Flemish hospital nurses. A multicenter questionnaire study was conducted in three hospitals using the Communication Satisfaction Questionnaire, the Turnover Intention subscale of the Questionnaire on the Experience and Evaluation of Work, and the Maslach Burnout Inventory.

Dedifferentiated Liposarcoma of the Retroperitoneum With Heterologous Osteosarcomatous Differentiation and a Striking Aneurysmal Bone Cyst-Like Morphology.

A 69-year-old woman with a 10-year medical history of recurrent retroperitoneal dedifferentiated liposarcoma presented with a 3-cm large hemorrhagic and multicystic left-sided retroperitoneal mass. Histopathological examination of the resected specimen showed a heterogeneous, high-grade mesenchymal nonlipogenic tumor with areas of osteoblastic/osteosarcomatous differentiation and aneurysmal bone cyst-like features. Based on the clinical presentation, the morphology, and the supportive immunohistochemical and molecular findings (MDM2 overexpression and amplification of the MDM2 gene, respectively), a diagnosis of a dedifferentiated liposarcoma with heterologous osteosarcomatous differentiation and an aneurysmal bone cyst-like morphology was made.

Software solutions alone cannot guarantee useful radiology requests.

Background The availability of clinical information and a pertinent clinical question can improve the diagnostic accuracy of the imaging process. Purpose To examine if an electronic request form forcing referring clinicians to provide separate input of both clinical information and a clinical question can improve the quality of the request. Material and Methods A total of 607 request forms in the clinical worklists for a computed tomography (CT) scan of the thorax, the abdomen or their combination, were examined.
