Pituitary tumor transforming gene-1 haplotypes and risk of pituitary adenoma: a case-control study [PDF]

BMC Medical Genetics, 2011
Background It has been suggested that pituitary adenoma results from accumulation of multiple genetic and/or epigenetic aberrations, which may be identified through association studies.

The Epigenomics of Pituitary Adenoma [PDF]

Frontiers in Endocrinology, 2019
Background: The vast majority of pituitary tumors are benign and behave accordingly; however, a fraction are invasive and are more aggressive, with a very small fraction being frankly malignant. The cellular pathways that drive transformation in pituitary neoplasms are poorly characterized, and current classification methods are not reliable correlates

Giant pituitary adenoma [PDF]

BMJ Case Reports, 2014
A healthy 68-year-old man presented in the emergency room with a sudden episode of headache and vomiting together with disequilibrium and crural paresis. The laboratory evaluation revealed hyponatraemia (Na+115 mEq/L). Head MRI demonstrated a giant 40×25×31 mm pituitary lesion (figures 1 and 2). Laboratory studies revealed growth hormone (GH) 0.1 ng/mL

The Genetics of Pituitary Adenomas [PDF]

Journal of Clinical Medicine, 2019
The genetic landscape of pituitary adenomas (PAs) is diverse and many of the identified cases remain of unclear pathogenetic mechanism. Germline genetic defects account for a small percentage of all patients and may present in the context of relevant family history. Defects in AIP (mutated in Familial Isolated Pituitary Adenoma syndrome or FIPA), MEN1 (

UniToPatho, a labeled histopathological dataset for colorectal polyps classification and adenoma dysplasia grading [PDF]

, 2021
Histopathological characterization of colorectal polyps allows to tailor patients' management and follow up with the ultimate aim of avoiding or promptly detecting an invasive carcinoma. Colorectal polyps characterization relies on the histological analysis of tissue samples to determine the polyps malignancy and dysplasia grade.

Collision sellar lesions: experience with eight cases and review of the literature [PDF]

, 2009
The concomitant presence of a pituitary adenoma with a second sellar lesion in patients operated upon for pituitary adenoma is an uncommon entity. Although rare, quite a great variety of lesions have been indentified coexisting with pituitary adenomas ...

Pituitary Adenoma Volumetry with 3D Slicer [PDF]

(2012) PLoS ONE 7(12): e51788, 2012
In this study, we present pituitary adenoma volumetry using the free and open source medical image computing platform for biomedical research: (3D) Slicer. Volumetric changes in cerebral pathologies like pituitary adenomas are a critical factor in treatment decisions by physicians and in general the volume is acquired manually.
