[INTRODUCTION - The occurrence of an adenomatoid tumour is rare in the uterus; in the female genitals it is more common in the Fallopian tube, whereas in men it mainly arises from the epididymis. Though there are controversies, its mesothelial origin seems to be confirmed. Apart from their different sites of occurrence, the mesothelioma and the adenomatoid tumour are distinguished by the fact that the latter is always circumscribed and never turns malignant. CASE REPORT - Two cases of adenomatoid tumour of the uterus are reported which had clinically been thought to be leiomyomata. Both of them were adenoid in type, and stained positive for cytokeratin and vimentin as well as for a mesothelial marker, but were negative for CD-34, whereas some cells of the adenoid epithelium showed positivity with ethidiummonoazide staining. CONCLUSION - The poor and non-specific clinical symptoms and course of this tumour warrants the reporting of such cases.]

[INTRODUCTION - Solitary fibrous tumor is a rare, in most of the cases benign tumor of mesenchymal origin arising from the pleura. CASE REPORT - Significantly raised right hemidiaphragm was noted on the chest X-ray of an elderly female patient with good general condition. A large solid mass lesion was seen above the normally positioned right hemidiaphragm on ultrasound and chest CT examinations. The mass was removed by surgical resection and a solitary fibrous tumor was confirmed by histological and immunhistochemical examinations. CONCLUSION - Solitary fibrosus tumor is a rare and histologically benign tumor. Occasionally it may enlarge rapidly and transform into malignant variant after several years. Therefore complete surgical resection and long term follow up is needed in all cases.]

[INTRODUCTION - Gestational and non-gestational choriocarcinoma, the two types of choriocarcinoma with distinct aetiologies, cannot be differentiated by conventional histological or immunohistochemical methods. In certain cases the verification of the origin of the tumour by molecular biological techniques is essential for prognostic and therapeutic reasons. CASE REPORT - A 22-year-old woman presenting with acute abdominal pain was examined and operated on. During surgery a tumour was found in the right ovary. “Pure” choriocarcinoma was histologically diagnosed and gestational origin was supposed based on the distinct clinical features and histological picture. This was subsequently confirmed by molecular genetic testing. Parallel VNTR (variable number of tandem repeats) analysis by PCR of DNA from the tumour tissue and the patient's peripheral blood was performed. The pattern showed the presence of an allele presumed to be of paternal origin. (Blood sample from the father was not available.) One regimen of Vepesid, Cisplatina and Bleomycin was applied, and more than three years after the diagnosis the patient is free of disease. CONCLUSION - Multidisciplinary cooperation led to an accurate diagnosis and successful treatment. Non-radical surgery with the preservation of fertility followed by proper early chemotherapy provided excellent results.]

[The objective assessment of the changes in the tumor burden along with cancer therapy has essential importance. Recently, the quantitative evaluation of the radiological tumor response was undergone several changes. For conventional chemotherapy of solid tumors the standard procedure has been RECIST since 2000. The targeted therapies trigger other pathophysiological changes in the cells than the cytotoxic agents, accordingly the morphological changes show a new picture. Therefore the targeted therapies require a new evaluation system, that takes into consideration not only the tumor size, but other changes as well, the changes of attenuation that corresponds with the proportion of the viable cells. In case of the targeted therapies in substantial clinical was experienced even without signifi cant morphological changes in the tumour size. As a consequence, the traditional, size-based criteria system can underestimate the effi ciency of the new types of treatments. To eliminate this problem new evaluation systems were created taking the tumortypes and treatment protocolls into consideration. The estimation of the early tumor response to targeted therapy also has high importance. In assessment of the response functional imaging methods are used more frequently. The role of PET has already been defi ned in numerous tumortypes, however the determination of the position of some promising functional examinations still require further studies.]

[Experiences about the breast diagnostic methods are accumulating year-to-year, rapidly. Therefore the current examination algorithm is changing continuously. New diagnostic and therapeutic modalities are entering into the daily practice. Some of them became obsolete, so far their application is becoming a faulty decision. Some other methods become obligatory steps in the diagnostics. These are the reasons why the up-to-date knowledge of the literature is mandatory. Systematic review of the most recent articles of the last two years (January 2005-December 2006) of breast radiological diagnostics and the actual place of the imaging and interventional methods are presented. The following topics are summarized: breast cancer screening with conventional and digital mammography, computer assisted diagnostics (CAD), high risk patients' screening, US, MRI, MSCT, PET/CT, diagnostic interventions, differential diagnostics, percutaneous tumour ablation, therapy-related questions in the diagnostic work up.]
