We report clinicopathologic features of a large series of renal translocation carcinomas from a multicentric study. Diagnosis was performed by cytogenetic examination of fresh material and/or by immunochemistry with antibodies directed against the C-terminal part of transcription factor E3 (TFE3) and native transcription factor EB (TFEB) proteins. Clinical(More)
Cystic kidney diseases and toxic interstitial nephritis may be complicated by renal tumors. Long-term lithium intake is associated with tubulointerstitial nephritis and renal cysts but to date such an association with tumors has not been determined. We evaluated this in a retrospective study to determine whether lithium-treated patients were at higher risk(More)
Mutations in one copy of the hepatocyte nuclear factors (HNF) 1alpha and 1beta homeodomain containing transcription factors predispose the carrier to maturity-onset diabetes of the young (MODY) types 3 and 5, respectively. Moreover, previous identification of biallelic inactivation of HNF1alpha in hepatocellular adenoma identified its tumor suppressor(More)
BACKGROUND Germline mutations in the folliculin (FLCN) gene are associated with the development of Birt-Hogg-Dubé syndrome (BHDS), a disease characterized by papular skin lesions, a high occurrence of spontaneous pneumothorax, and the development of renal neoplasias. The majority of renal tumors that arise in BHDS-affected individuals are histologically(More)
BACKGROUND The proband, a 33-year-old woman, presented with renal cysts, mild renal failure and a renal tumor. One of the proband's two sons had hyperechogenic kidneys and the other had renal cortical microcysts. Her 71-year-old mother had mild renal failure and small renal cysts. INVESTIGATIONS Ultrasonography, blood and urine analysis, MRI, CT scan, and(More)
Rosai-Dorfman disease (RDD) is a rare disorder, often benign but with possible life-threatening prognosis. In most cases, specific treatment is not necessary; when required, the management of RDD is not codified to date, and various chemotherapies have been shown to be ineffective. Here, we report a patient with RDD who presented a dramatic and sustained(More)
Although most classical Hodgkin lymphoma patients are cured, a significant minority fail after primary therapy and may die as result of their disease. To date, there is no consensus on biological markers that add value to usual parameters (which comprise the International Prognostic Score) used at diagnosis to predict outcome. We evaluated 59 patients (18(More)
We report a case of a 16-year-old girl with a left renal tumor discovered by her family practitioner. On physical examination the patient had a painless abdominal mass, located in the upper medium portion of the abdomen on the left side with a voussure of the abdominal wall. Ultrasound and abdominal pelvic CAT scan revealed a large heterogeneous mass with(More)
Androgen receptor (AR) is essential for testicular physiology and spermatogenesis. SRC-2 and HBO1 are two AR coregulators yet their expression and roles in human testis are unknown. For the first time, we studied by immunohistochemistry and RT-PCR, the expression and distribution of these two coregulators during human testicular ontogenesis, in patients(More)
Most renal tumors of the adult are carcinomas. Their treatment is surgical, consisting of limited excision or nephrectomy. In some instances, biopsy of the tumor can be performed in order to adapt treatment. We report the case of a 45 year-old woman presenting with renal tumor. A biopsy of the mass showed a metanephric adenoma. No surgical excision was(More)
