Banris Other transformation markers of PAs have been proposed, including cathepsin B or metalloprotease-9 MMP-9the assessment of proliferation activity using antiapoptotic markers such as bcl-2, the analysis of DNA topoisomerase II-alpha indices, cyclooxygenase II expression, the detection of telomerase expression, or studies with galectin A year-old female without relevant medical history was referred to our service for an asymptomatic swelling in the right cheek of craneofaringiooma year of evolution.

J Clin Endocrinol Metab, 80pp. Neuroimaging techniques, both computed tomography and MRI, are useful for characterizing the lesion. A report of two clinical cases.

Clinical outcome in children with recurrent craniopharyngioma after primary surgery. Associated with complex odontoma: The postoperative evolution was satisfactory without complications after one year following. There are some clinically non-functioning PAs in which, despite the absence of the clinical syndrome or hormone hyposecretion or hypersecretion, an IHC labeling pattern and an ultrastructural appearance consistent with a secretory adenoma are seen.

Radiographically, radiolucid unilocular 1,2 and, occasionally, multilocular images are seen 3,11,13 with well-circumscribed limits that contains diffuse radiopacities areas 2, The great majority of these tumors show a diffuse growth pattern. As the result of development in recent years of new immunohistochemical techniques, histopathological classification has become more complex and wide, and not only continues to be the gold standard in diagnosis, but also has prognostic implications.

Documentos de los Grupos de Trabajo. With new biomarkers for aggressive PAs and new data on genetic abnormalities associated with pituitary tumor pathogenesis, it is to be hoped that the relationship between typical and atypical adenomas and carcinomas is now clarified, thus allowing for greater diagnostic and prognostic accuracy. Morphologically, they consist of elongated piloid cells arranged in bundles, in a pattern that resembles a pilocytic astrocytoma however, unlike pilocytic astrocytoma, most pituicytomas lack the biphasic pattern, the characteristic Rosenthal fibers, and eosinophilic granular bodies.

It arises from odontogenic epithelial rests present in the maxilla, jaw or gum. Both cases presented correspond to intra-osseal variant and the common sign for both cases was an increase of asymptomatic non-tender swelling, without ganglion compromise. The purpose of this article is to present a review of the literature related to these two cases of OCCT and its treatment, putting craneofaringiooma emphasis on its aetiology, biological behaviour and treatment.

All other tumors are very rare lesions 2 that mimic PAs in neuroimaging studies, so that the final diagnosis should be made by the pathologist. Cystic lesions of the pituitary: Acta Radiol, 36pp. Growth hormone release after glucagon as a reliable test of growth hormone assessment in adults.
