ABSTRACT: Primitive neuroectodermal tumors (PNET) represent 1% of sarcomas. Head and neck peripheral PNETs have an intermediate prognosis between abdominopelvic disease and extremities. We here report the case of a 40-year old male who presented with primitive neuroectodermal tumor of the thyroid and was treated by multimodal treatment,...

The recent identification of fusion genes involving ETS family members in human prostate adenocarcinoma has confirmed the hypothesis that recurrent specific aberrations such as fusion genes may be as frequent in epithelial tumors as they are in leukemias and sarcomas. However, reciprocal translocations with fusion genes are often not detectable...

Histological features are usually sufficient for providing an accurate diagnosis of renal cell carcinomas (RCC). However, the morphological appearance might sometimes be misleading. For instance, RCC with papillary areas and extensive clear cell changes may be difficult to classify either as clear cell renal carcinoma or as papillary renal cell...
Renal cell carcinoma (RCC) with translocation involving Xp11.2 (Xp11.2-RCC) is a rare neoplasm that usually occurs in children and young adults. This incidence is underestimated in adults because its morphological similarities with clear-cell RCC or papillary RCC2,3, as well as immunohistochemical and cytogenetic analyses are not carried out...
The aim of our study was first to assess the role of HMGA2 expression in the pathogenesis of adipocytic tumors (AT) and, second, to seek a potential correlation between overexpression of HMGA2 and let-7 expression inhibition by analyzing a series of 56 benign and malignant AT with molecular cytogenetic data. We measured the levels of expression...
PURPOSE: The MDM2 and HMGA2 genes are consistently amplified in well-differentiated/dedifferentiated liposarcomas (WDLPS/DDLPS) whereas CDK4 is frequently but not always amplified in these tumors. Our goal was to determine whether the absence of CDK4 amplification was (a) correlated to a specific clinico-histopathologic profile; and (b)...
BACKGROUND: EGFR (epidermal growth factor receptor) gene gain assessed by FISH (fluorescence in situ hybridization) has been shown to be predictive of response to EGFR-targeted therapies in patients with non-small cell lung cancer. The aim or our study was to relate the EGFR gene copy number to therapeutic results in patients with metastatic...
