Pituitary Neoplasm Nomenclature Workshop: Does Adenoma Stand the Test of Time? / Luis Vicente Syro Moreno    

Público ISBD Título : Pituitary Neoplasm Nomenclature Workshop: Does Adenoma Stand the Test of Time? Tipo de documento : documento electrónico Autores : Luis Vicente Syro Moreno, Fecha de publicación : 2021 Títulos uniformes : Journal of the Endocrine Society Idioma : Inglés (eng) Palabras clave : Pituitary neoplasm  neuroendocrine  pituitary adenoma  tumor Resumen : The WHO Classification of Endocrine Tumours designates pituitary neoplasms as adenomas. A proposed nomenclature change to pituitary neuroendocrine tumors (PitNETs) has been met with concern by some stakeholder groups. The Pituitary Society coordinated the Pituitary Neoplasm Nomenclature (PANOMEN) workshop to address the topic. Experts in pituitary developmental biology, pathology, neurosurgery, endocrinology, and oncology, including representatives nominated by the Endocrine Society, European Society of Endocrinology, European Neuroendocrine Association, Growth Hormone Research Society, and International Society of Pituitary Surgeons. Clinical epidemiology, disease phenotype, management, and prognosis of pituitary adenomas differ from that of most NETs. The vast majority of pituitary adenomas are benign and do not adversely impact life expectancy. A nomenclature change to PitNET does not address the main challenge of prognostic prediction, assigns an uncertain malignancy designation to benign pituitary adenomas, and may adversely affect patients. Due to pandemic restrictions, the workshop was conducted virtually, with audiovisual lectures and written précis on each topic provided to all participants. Feedback was collated and summarized by Content Chairs and discussed during a virtual writing meeting moderated by Session Chairs, which yielded an evidence-based draft document sent to all participants for review and approval. There is not yet a case for adopting the PitNET nomenclature. The PANOMEN Workshop recommends that the term adenoma be retained and that the topic be revisited as new evidence on pituitary neoplasm biology emerges.

Pituitary adenoma with peliosis: a report of two cases / Luis Vicente Syro Moreno  

Público ISBD Título : Pituitary adenoma with peliosis: a report of two cases Tipo de documento : documento electrónico Autores : Luis Vicente Syro Moreno, Fecha de publicación : 2009 Títulos uniformes : Endocrine Pathology Idioma : Inglés (eng) Palabras clave : Oncology  pathology  peliosis  pituitary  pituitary neoplasm  vasculogenic mimicry Resumen : Peliosis is characterised by multiple blood-filled lakes or cavities within parenchymatous organs. Typically found in the liver, spleen, bone marrow and lymph nodes, it has also been described in other organs such as lungs, kidneys, parathyroids and pancreas. The mechanism responsible for the development of peliosis remains unknown. (1) A 69 year-old man with a 6-year history of acromegaly underwent transsphenoidal surgery for pituitary adenoma. Morphologic findings demonstrated a plurimorphous plurihormonal pituitary adenoma consisting of somatotrophs, lactotrophs and mammosomatotrophs. The tumor contained several blood-filled cavities characteristic of peliosis. (2) A 61-year-old man with a prolactin-producing pituitary adenoma who underwent transsphenoidal surgery. In the tumor, peliosis was noted. Peliosis in a pituitary adenoma is an intriguing finding. The question arises whether it represents vasculogenic mimicry.

Double adenoma of the pituitary: a somatotroph adenoma colliding with a gonadotroph adenoma / Luis Vicente Syro Moreno  

Público ISBD Título : Double adenoma of the pituitary: a somatotroph adenoma colliding with a gonadotroph adenoma Tipo de documento : documento electrónico Autores : Luis Vicente Syro Moreno, Fecha de publicación : 2000 Títulos uniformes : Journal of Endocrinological Investigation Idioma : Inglés (eng) Palabras clave : Pituitary neoplasm  pathology  histology  immunocytochemistry  ultrastructure  acromegaly  somatotroph adenoma  gonadotroph adenoma  double adenomas  collision tumors Resumen : Pituitary collision tumors are rare. They may create difficult diagnostic problems and their histogenesis is not clear. We report here an unusual case of a somatotroph adenoma colliding with a gonadotroph adenoma.The 64-year-old man had clinical acromegaly. His blood growth hormone level was elevated and magnetic resonance imaging demonstrated a pituitary tumor. The surgically removed sellar mass was investigated by histology, immunocytochemistry and electron microscopy. Morphologic study revealed a collision tumor; one was a somatotroph adenoma, the other a gonadotroph adenoma. Authors call attention to the difficulties in clinical, imaging and pathological diagnosis. Detailed morphologic studies are needed to establish the presence of two distinct tumors composed of two different cell types. Mención de responsabilidad : L. V. Syro, E.
