Somatotropinomas are benign pituitary tumors, with a heterogenous biological and clinical behavior. Tumor microenvironment reflects the interaction between tumor cells and the host immune system and may regulate tumor behavior and therapy outcome. We develop a scoring system that includes clinical, pathological and immune markers to early identify fg-SRLs resistant acromegaly pts. 43 acromegaly pts were included according the following criteria (1) first line treatment with su...

Acromegaly is associated with skeletal fragility and an increased prevalence of vertebral fractures (VF). In recent years several authors have tried to investigate the markers that can predict the risk of bone fragility in this endocrine disorder. Two different isoforms of the GH receptor (GHR) have been described so far, which differ in the presence or absence of a transcript of exon 3 of the GHR gene. Both isoforms produce a functional receptor, but the exon 3-deleted isofor...

Introduction: Infundibulo-neurohypophysitis (INH) is an uncommon inflammatory disorder. Because of the location of inflammation, it selectively affects the neuropituitary and pituitary stalk. The differential diagnosis remains often challenging with neoplastic lesions, such as germ cell neoplasia, Langerhans cell histiocytosis, Erdheim-Chester Disease, metastasis. Our clinical case is emblematic for pitfalls in diagnosis of the pituitary stalk lesionCase...
