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.
