CONTEXT Lymphocytic anterior hypophysitis in association with a pituitary adenoma was reported previously. In rare instance, inflammatory infiltration was confined to adenoma tissue itself, excluding anterior pituitary. CASE The patient - a 27-year-old male - presented with visual field defect. Further examination revealed a pituitary mass with suprasellar extension. Hormonal evaluation indic...

PURPOSE Pituitary adenomas are the most common cause of an optic chiasmal syndrome, and treatment of these lesions is considerably different from the treatment of most of the other lesions in this region. Although the diagnosis of a pituitary adenoma is usually inferred from the results of neuroimaging, lesions other than pituitary adenomas can have an appearance that suggests an adenoma. The o...

BACKGROUND Thyrotropin-producing pituitary tumor is relatively rare. In particular, concurrent cases associated with Graves' disease are extremely rare and only nine cases have been reported so far. We describe a case of a thyrotropin-producing pituitary adenoma concomitant with Graves' disease, which was successfully treated. CASE PRESENTATION A 40-year-old Japanese woman presented with mild...

A macroinvasive pituitary adenoma with plurihormonality usually causes acromegaly and hyperprolactinemia, and also accompanies with neurologic symptoms such as visual disturbances. However, its concurrent presentation with a rectal carcinoid tumor is rarely observed. This study reports the history, biochemical, colonoscopic and immunohistochemical results of a 48-year-old female with acromegaly...

Nucleostemin is a GTP-conjugated protein located in the nucleoli of stem cells and certain cancer cells, and maintains cellular self-renewal. The present study aimed to evaluate nucleostemin as a potential target for pituitary adenoma gene therapy by investigating nucleostemin and apoptosis-stimulating of p53 protein 2 (ASPP2) expression and their effect on pituitary adenoma cell proliferation....

We describe the occurrence of a supracellar ectopic pituitary adenoma in a 34 year old woman who presented with cranial diabetes insipidus and subsequently developed galactorrhoea-amenorrhoea. The tumour was demonstrated by both contrast computed tomography scan and magnetic resonance imaging with gadolinium enhancement and was confirmed at operation. Histological examination showed that the su...

INTRODUCTION Ectopic pituitary adenoma is defined as adenoma that occurs outside the sella without any continuity with the normal pituitary gland [1]. Since its description for the first time in 1909 by Erdheim in the vomero-sphenoidal region, about 75 cases have been reported in literature [2-12]. Sphenoid sinus followed by the suprasellar region remains the most common site for these adenomas...

UNLABELLED We report a case with Non-Hodgkin Lymphoma with a focus of intense hypermetabolism in the sellar region in the primary staging and posttreatment whole body F-18 FDG PET. Further evaluation with magnetic resonance imaging after posttreatment FDG PET revealed a pituitary adenoma. Endocrinologic workup was normal consistent with nonfunctioning pituitary adenoma and endocrinologists deci...

BACKGROUND There are few studies of the incidence and clinical characteristics of pituitary apoplexy (PA) in pituitary adenoma patients, and the findings have been inconsistent. OBJECTIVE The aim of the study was to retrospectively assess the incidence, clinical presentation, surgical management and postoperative complications of PA in pituitary adenoma patients. METHODS A database was spec...

Background & Aim: We described the presentation, management and subsequent treatment outcomes of children and adolescents diagnosed with a pituitary adenoma in a joint neuroendocrine setting followed up by a single service as well as assessing long-term outcomes in terms of endocrine status and neurology symptoms. Methods & Materials/Patients: A total of 21 participants with histologically v...
