..Our results indicate that there is no IDH1 gene involvement in the onset and progression of pediatric astrocytomas. We argue that it is not useful in children to assess the status of IDH1 gene nor for diagnostic nor prognostic purposes...

..We suggest that liponeurocytoma is an uncertain malignant potential lesion when mitoses are present and the MIB-1 positive cells are more than 10%...

..We speculate on the histogenesis of teratoid hepatoblastoma and discuss its association with chemotherapy...

..Particularly, the combination of liquid-based endometrial cytology and transvaginal sonography may improve their diagnostic accuracy and reduce unnecessary more invasive and expensive procedures...

..013). Our data supports the finding that alterations in NF2 gene alteration are histotype related but not grade related...

....

..These results may indicate MGMT as a factor of chemoresistance to alkylating drugs in anaplastic ependymomas and support the uncertainties regarding the actual benefit of chemotherapy for patients with anaplastic ependymomas...

..In order to assess the utility of the liquid-based method in endometrial diagnosis, we evaluated its accuracy in comparison with histology...

..It could be usefully applied in association with transvaginal sonography. The combination of these procedures might reduce more invasive and expensive diagnostic procedures...

....

..The algorithm for the diagnosis of congenital/infantile fibrosarcoma, especially outside the usual localizations, should comprise morphologic, immunohistochemical, molecular, and ultrastructural studies...

..Our results emphasize the glio-neuronal nature of SEGA. We suggest moving it into the group of mixed glio-neuronal tumors under the denomination of subependymal giant cell tumor...

..The aim of this study was to evaluate the utility of liquid-based cytology for endometrial surveillance in patients receiving tamoxifen...

..This article proposes that papillary glioneuronal tumor should be included in the differential diagnosis of patients with tumoral related brain hemorrhage...

..Nevertheless, the absence of statistical correlation with survival time advises further studies on larger series to ascertain the concrete prognostic value of COX-2 in glioblastoma...

..The patient is alive and well at 18-month follow-up. The case presented provides evidence that pilomyxoid astrocytoma can occur at a later age and can arise in regions different from hypothalamic/chiasmatic...

..As evident from this case report, amniotic band syndrome may cause severe malformations and foetal-infant death...

..We believe each new case should be recorded to produce a better clinical, pathologic, molecular, prognostic, and therapeutic characterization of this lesion...

..Statistical analysis did not prove significant differences. Our results suggest that NF2 alterations are not typical of intracranial anaplastic ependymomas...

..Rhabdoid meningiomas rarely occur in children. Owing to its rarity, each new case should be recorded to produce a better clinical, pathological, molecular, prognostic and therapeutic characterization of this lesion...

..In asymptomatic postmenopausal women cytology gave sufficient material for the diagnosis significantively more often than endometrial biopsy (respectively 82% and 24%; p = 0.000)...

..At follow-up 6 months after surgery the patient is well. Calcified cystic lymphangioma of the mesentery should be considered in the differential diagnosis of an intra-abdominal calcified cyst in children...

....

..The Ki-67 index was low. The clinicopathologic profile and the differential diagnosis of this tumor are discussed...

..The published literature on the meningioma-primary cerebral lymphoma association is revised...

..Nevertheless, t(14;18) (q32;q21), as evaluated by traditional PCR, may not correspond to diffuse immunohistochemical BCL-2 positivity...

..Owing to the rarity of embryonal tumor with abundant neuropil and true rosettes, each new case should be recorded to produce a better clinical, pathological and molecular characterization of this lesion...

....

..In this study, we hypothesize that the presence of T cells with the T-cell receptor gamma complex may play a particular role in carcinogenesis and tumor progression...

..In atherogenesis, dendritic cells, beside presenting antigens, may be sources of tumour necrosis factor (TNF)alpha and nitric oxide (NO), together with mast cells and smooth muscle cells...

..Furthermore, we go into the difficulty of discerning the villous capillary lesions and the utility of this division, and describe the clinical effects of these lesions on fetal outcome...

..Since its first report, 37 cases have been described in the literature. We report on an additional case that we considered significant because of its incidental detection and its uneventful surgical removal...

..Normal tissues show estrogen receptor beta expression greater than pathologic tissues and the estrogen receptor beta result as most expressed in the lower disease stages...

..However, the true behavior of, and the long-term follow-up data for, such lesions must still be outlined...

..The different roles of HOX and integrin genes in gastric carcinoma remain to be fully elucidated. These findings suggest that the HOX genes may play a critical role in the genesis, maintenance and diffusion of gastric carcinoma...

..The aim of the study was to investigate the distribution of the sialoderivatives of the glycoconjugates in the oviduct of normally menstruating and postmenopausal women...

..The heterogeneous PFS in our patients treated with second line TMZ, indicates that MGMT expression alone is insufficient to predict the response to TMZ, presumably because of the DNA repair mechanisms involved...

..The authors emphasize the role of the morphological and immunohistochemical evaluations to recognize this rare tumor...

..NF2 gene mRNA expression was assessed in fresh tissue of stomach from 5 consecutive patients. We detected no alterations in NF2 gene expression in the quantitative analyses of the 5 tumors...

..We report an additional case of oncocytic meningioma investigated by ultrastructural and immunohistochemical methods...

..Close histologic follow-up is required, and immediate surgery is mandatory if endometrial cancer persists...

..Some fetuses and infants died from various causes, indicating that a close follow-up is necessary in these pregnancies..

..He is alive with persistent severe visual disturbance 14 months after the diagnosis. We discuss the etiopathogenetic, diagnostic, and therapeutic issues related to this entity, and review the literature...

..Pathological examination showed that the stalk was formed of hamartomatous tissue. The patient improved following surgery, which suggested that tethering of the cervical spinal cord was responsible for his symptoms...

..Therefore, in relative expression quantization, we confirm that it is appropriate to use specimens with same protocols and time for formalin fixation...

..This case report confirms that the presence of choroid plexus is not uncommon and that pharyngeal brain heterotopia is usually benign...

..After diagnosis the patient began thyroid and adrenal-replacement therapy and was referred to Radiotherapy Unit for treatment on the sellar and pituitary gland region...
