Serotonin-producing pancreatic endocrine tumour. Histological, ultrastructural and immunohistochemical study of a case.

abstract：:Peritumoral brain edema (PTBE) is considered to be one of the main biological behaviors of brain glioma. However, the histopathological features of PTBE remain imprecisely defined. We analyzed the histopathological characteristics in the PTBE area of 22 cases of glioma. Microscopically, the pre-existing basic structur...
