Craniopharyngiomas (CP) ectopic localizations off the midline outside the sellar-suprasellar region are very rare and most often associated to secondary tumor dissemination, being primary ectopic CPs extremely unusual. We herein report the first case of a primary ectopic craniopharyngioma within the orbit. A 15-year-old patient presented with progressive right ptosis, proptosis, and retro ocular pain. Magnetic resonance imaging (MRI) showed a predominantly cystic lesion, occupying the superolateral right corner of the orbit, outside the intraconal space with no evidence of intracranial involvement. An endoscopic transorbital eyelid approach was adopted. Pathology report disclosed a primary ectopic craniopharyngioma.

Hyperparathyroidism-jaw tumor syndrome (HPT-JT) is a rare hereditary disorder caused by pathogenic gene variants. We report the case of a patient with HPT-JT who carried a novel germline pathogenic variant. A 27-year-old woman presented with thirst, polyuria, fatigue, constipation, and a history of fibro-osseous mandible lesions and endometrial polyps.

Melanocortin therapeutics, exemplified by adrenocorticotropic hormone, have a proven steroidogenic-independent anti-proteinuric and glomerular protective effect. The biological functions of melanocortins are mediated by melanocortin receptors (MCR), including MC1R, which recent studies have shown to protect against glomerular disease. However, the role of other MCRs like MC5R is unknown.

Background: Increased fructose consumption contributes to type 2 diabetes (T2D) and metabolic dysfunction-associated steatotic liver disease (MASLD), but the mechanisms are ill-defined. Gut nutrient sensing involves enterohormones like Glucagon-like peptide (Glp)2, which regulates the absorptive capacity of luminal nutrients. While glucose is the primary dietary energy source absorbed in the gut, it is unknown whether excess fructose alters gut glucose sensing to impair blood glucose regulation and liver homeostasis.
