Improving differential diagnosis of pituitary adenomas / Carlos Esteban Builes Montaño ; Luis Vicente Syro Moreno
Título : Improving differential diagnosis of pituitary adenomas Tipo de documento : documento electrónico Autores : Carlos Esteban Builes Montaño, ; Luis Vicente Syro Moreno, Fecha de publicación : 2014 Títulos uniformes : Expert Review of Endocrinology and Metabolism Idioma : Inglés (eng) Palabras clave : Classification diagnosis familial syndrome genetics pathology pituitary adenoma Resumen : Pituitary adenomas are common tumors arising in adenohypophysial cells or their precursors. For improving control of the disease an early diagnosis is important. Initially considered sporadic tumors, some of them are associated with familial syndromes and their recognition and classification is also required. Morphologically, pituitary adenomas represent a heterogeneous group of tumors with several subtypes and different clinical behavior thus a precise pathological diagnosis is crucial. The simple diagnosis of pituitary adenoma is not satisfactory and the correct classification of histological subtypes may predict aggressiveness in the majority of cases. Although considered not malignant, some of them are clinically aggressive and their recognition remains a challenge. In this paper we present the recent advances in the event of improving early recognition and differential diagnosis of pituitary tumors.

Título : Pituitary ganglioneuroma: case report and literature review Tipo de documento : documento electrónico Autores : Luis Vicente Syro Moreno, Fecha de publicación : 2014 Títulos uniformes : Journal of Cytology and Histology Idioma : Inglés (eng) Palabras clave : Electron microscopy ganglioneuroma. immunohistochemistry neuronal tumors pituitary neoplasms Resumen : We present a case of pituitary ganglioneuroma occurring in a 25 year old woman who presented with headache and hemianopsia. The histologic, immunohistochemical, and ultrastructural features of this tumor support the view that these rare hypothalamic-pituitary tumors are independently functioning neurohormonal units. Immunostaining is strongly positive for neuron-specific enolase (NSE) in all tumor cells and cell processes and for synaptophysin in a few cells and fibers. Few cells closely associated with tumor cells are positive for S100 protein. The cell processes are positive for neurofilament antigen. Ultrastructural analysis documents a spectacular neoplasm of neural derivation. The tumor consists of ganglion cells and areas of neuropil. The most typical tumor cells have relatively lucent spherical nucleus with large nucleolus, and abundant cytoplasm harbors compact sacks of RER membranes studded with ribosomes. Particular emphasis is given to the ultrastructural features which strongly support the functional relationship between the tumor components. It should be kept in mind that unusual and rare ganglionic tumors might show a progressive clinical course and needs surgical intervention as the major part of their treatment whereas ontogenetic and pathogenetic mechanisms taking part still need more work to enlighten pituitary neuronal tumorigenesis.

Título : Ghrelin: A GH-releasing, appetite-regulating gastric hormone Tipo de documento : documento electrónico Autores : Luis Vicente Syro Moreno, Fecha de publicación : 2013 Títulos uniformes : Advances in Neuroimmune Biology Idioma : Inglés (eng) Palabras clave : Growth hormone stomach orphan receptor Resumen : Ghrelin is a hormone that stimulates growth hormone (GH) release, and regulates appetite and feeding habits. It is synthesized and expressed to varying degrees in several organs and neoplasms. Its presence has been reported in the gastrointestinal and respiratory tracts, endocrine organs, cardiovascular system, kidney and central nervous system. Ghrelin producing cells can be demonstrated in the stomach, intestines, pancreas, kidneys, brain, and pituitary. The present review summarizes findings regarding the function and regulation of ghrelin in different organs and in various diseases.

Título : Melanoma of the sellar region mimicking pituitary adenoma Tipo de documento : documento electrónico Autores : Luis Vicente Syro Moreno, Fecha de publicación : 2013 Títulos uniformes : Neuropathology Idioma : Inglés (eng) Palabras clave : Histology melanoma neoplasm pathology pituitary Resumen : We report here the case of an 82‐year‐old woman who presented with visual disturbance. MRI demonstrated a sellar mass. The diagnosis of pituitary adenoma was made. She underwent transnasal surgery. Histologic, immunohistochemical and ultrastructural studies indicated that the tumor was a melanoma. Despite an exhaustive search for a primary lesion elsewhere, none was found. The sellar tumor was considered a primary lesion, although extrasellar primary tumor imaging cannot be excluded with 100% certainty. Reported examples of melanoma affecting the sellar region are few. They exhibit morphologic features identical to those of melanomas arising elsewhere. Although very rare, primary melanomas enter into the differential diagnosis of sellar lesions.

Título : Microvessel density and VEGF expression in pituitaries of pregnant women Tipo de documento : documento electrónico Autores : Jorge Hernando Donado Gómez, ; Luis Vicente Syro Moreno, Fecha de publicación : 2013 Títulos uniformes : Hormones Idioma : Inglés (eng) Palabras clave : Angiogenesis Immunohistochemistry Pituitary Pregnancy Vascular endothelial growth factor Resumen : Objective: In pregnant women, the pituitary is enlarged and the prolactin (PRL) secreting cells increase in size and number. This PRL cell hyperplasia is associated with hyperprol-actinemia. The aim of the present work was to investigate adenohypophysial vascularization and immunoexpression of vascular endothelial growth factor (VEGF) in pituitaries of pregnant and post-partum women and compare the results with age-matched adenohypophyses of non pregnant women who had no endocrine diseases. Design: Pituitaries (n=18) obtained by autopsy from female patients of reproductive age who had died during pregnancy, after abor- tion or during post-partum were immunostained for CD-34 and VEGF using the streptavidin-biotin-peroxidase complex method. Results: The results showed that microvessel densities and VEGF immunoexpression in the adenohypophyses of pregnant and post-partum women were similar to those found in the control pituitaries. Conclusion: It can be concluded that pituitary enlargement and PRL cell hyperplasia in pregnant women may occur without neovascularization and increased VEGF immunoexpression.
