Introduction: Pituitary inflammation (Hypophysitis) is rare in paediatric population and usually results in pituitary enlargement and hypopituitarism. Hypophysitis can be either primary (most commonly lymphocytic, granulomatous or xanthomatous disease) or secondary (consequent to systemic diseases, immunotherapy or alternative sella-based pathologies). We describe the clinical presentation and management of apparent primary lymphocytic hypophysitis in an adolescent girl. Case ...

Background: It is generally accepted that a post-operative cortisol of <50 nmol/l is a good predictor of long-term remission following trans-sphenoidal surgery (TSS).Aim: We wished to determine the rate of late recurrence and need for consequent intervention in patients who had initial biochemical remission after TSS for pituitary dependent Cushing’s.Methods: We performed a retrospective analysis of our patients who underw...

Introduction: In 2017 the term ‘Atypical adenoma’ was removed from the WHO classification, and ‘High-risk adenomas’ was introduced as a term to classify those with rapid growth, radiological invasion, and a high Ki-67 proliferation index. In this retrospective cohort study we have sought to identify the clinical and histological characteristics which are associated with worse outcomes.Methods: Data: We created a dataset of 1793 pa...

Temozolomide has an established role as first line chemotherapy for aggressive pituitary adenoma and carcinoma. There are mixed reports whether the MGMT (methylguanine methyltransferase) and mismatch repair protein (MSH2/6) status of a tumour, assessed by immunohistochemistry (IHC) can predict response to temozolomide. This is the first series to assess combined MGMT and MSH2 status. We analysed a retrospective case series of patients treated with temozolomide at our tertiary ...
