Pigmented Papillary Epithelial Neoplasm of the Pituitary Fossa

Archives of Pathology & Laboratory Medicine, 2001
Abstract Primary pigmented intracranial neoplasms are strikingly uncommon. The differential diagnosis is limited and includes both epithelial and nonepithelial tumors, most of which arise within or near the ventricular system. The authors describe a 42-year-old man who presented with a pigmented papillary epithelial lesion that arose ...

P53 mutations in human adrenocortical neoplasms [PDF]

, 1994
The mechanisms of tumorigenesis of adrenocortical neoplasms have not been elucidated as yet. However, loss of heterozygosity at chromosomal locus 17p has been consistently observed in adrenocortical cancer.

Juvenile granulosa cell tumour of the ovary presenting with hyperprolactinaemic amenorrhoea and galactorrhoea [PDF]

, 2016
Secondary amenorrhoea and galactorrhoea represent a common endocrine presentation. We report a case of an oestrogen-producing juvenile granulosa cell tumour (JGCT) of the ovary in a 16-year-old post-pubertal woman with hyperprolactinaemia amenorrhoea and

An Investigation of Hyperostosis Frontalis Interna in a Modern Anatomical Body Donor Population

Clinical Anatomy, EarlyView.
ABSTRACT This research sought to examine the prevalence and severity of hyperostosis frontalis interna (HFI) in the Chicagoland anatomical body donor population. The study further aimed to elucidate potential demographic risk factors for HFI, including sex, age at death, and structural vulnerability index (SVI), as well as any common comorbidities, as ...

Ontogeny of RSPO1, FOXL2, and RUNX1 during ovarian differentiation in the marsupial tammar wallaby

Developmental Dynamics, EarlyView.
Abstract Background RSPO1 and FOXL2 are female sex‐determining genes involved in the differentiation and organization of the ovary in some eutherian mammals. Mutations or loss of function of these genes are associated with partial to full sex reversal in mice, humans, and goats.

Gut‐microbiota‐brain Axis and post‐traumatic epilepsy

Epilepsia Open, EarlyView.
Abstract There has been growing evidence that perturbations in gut‐microbiota‐brain axis (GMBA) are involved in mechanisms of chronic sequelae of traumatic brain injury (TBI). This review discusses the connection between GMBA and post‐traumatic epilepsy (PTE), the latter being a common outcome of TBI.

The Epigenomics of Pituitary Adenoma

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.

Pituitary Metastatic Composite Tumors: A Case Report with Next-Generation Sequencing and Review of the Literature

Case Reports in Oncological Medicine, 2020
Background. While pituitary tumors are well understood, little research has been done on metastasis from primary tumors into pituitary adenomas, also known as composite tumors. Because only 34 cases of composite tumors have been reported to date, we hope
