Angiomyolipomas are benign mesenchymal tumours originating from the kidney and adrenals. They are rare tumours that can be sporadic and isolated or occur as a part of tuberous sclerosis. These tumours have a high content in the cells, which is pathognomonic for diagnosis using ultrasonography, computed tomography and magnetic resonance imaging. Atypical angiomyolipomas occur with excessive smo...
This review discusses the impact of molecular genetics on the diagnosis and prognosis of renal cell tumours as well as the genetic changes in renal cell tumours associated with von Hippel-Lindau disease and end-stage kidney disease. The use of molecular techniques enables the division of renal cell tumours into genetically and biologically well defined entities. The new classification system di...
Wilms tumour is an embryonal tumour of childhood that closely resembles the developing kidney. Genomic changes responsible for the development of the majority of Wilms tumours remain largely unknown. Here we identify recurrent mutations within Wilms tumours that involve the highly conserved YEATS domain of MLLT1 (ENL), a gene known to be involved in transcriptional elongation during early devel...
Sir, We read the article by Belloni-Fortina et al. (1) with great interest. This retrospective study focused on the incidence of, and risk factors for, skin complications among liver transplant patients. They concluded that in these recipients the risk of premalignant and malignant skin lesions was lower than that of other solid organ transplants. Although organ transplant recipients are predis...
BACKGROUND Metastases to the thyroid are encountered rarely in clinical practice, but the number of cases seems to have increased in recent years. The reason of this increase may be a more frequent use of fine-needle aspiration biopsy (FNAB) and the use of more sophisticated, complicated imaging techniques in patients with thyroid masses. Also, in addition to these reasons, the use of more orga...
Von Recklinghausen's neurofibromatosis (NF-1) is a phacomatosis characterised by widespread nervous system tumours with cutaneous manifestations and variably associated anomalies. We report here a case, who, in addition to classical features of NF-1 (café-au-lait spots, cutaneous and subcutaneous neurofibromas) demonstrated radiological evidence of both spinal and intracranial neurofibromas and...
Primary sarcomas of the kidney are exceptional, representing 1 to 3% of all renal tumours in adults. They have a poor prognosis. The authors report a case of primary leiomyosarcoma of the kidney in a 44-year old patient, presenting in the form of low back pain and haematuria. Treatment consisted of radical nephrectomy. Two months later, the patient presented with hepatic metastases. The patient...
The comparison of several statistical methods currently used for detection of differentially expressed genes was attempted both by a simulation approach and by the analysis of data sets of human expressed sequence tags, obtained from UniGene. In the simulated mixed case, mimicking a situation close to reality, the general chi(2) test was unexpectedly the most efficient in multiple tag sampling ...
ewing sarcoma is about 10 % of bone tumours, in the form of lytic, sclerotic and mixed type. the lytic type erodes the whole bone in such a way that the auther would like to name it 'vanishing' type and recognition of this radiological type is of great importance from differential point of view in the study of primary and secondry tumours of bones.
Primitive neuroectodermal tumor (PNET) of the kidney is rare. Mostly patients with renal PNET are young adults and the survival rates are poor. Although radiological and pathological investigations, differential diagnosis from other kidney tumours is very difficult. The treatment is often delayed because of difficulties with diagnosis. In most cases of renal PNET, as in this case, prognosis is ...
