Introduction: Paragangliomas are neuroendocrine tumors that are derived from the embryonic neural crest cells. Because the paraganglia are widespread through the body, paragangliomas can be found in unusual anatomic locations and the diagnosis can be hard to establish. Case presentationWe present the case of an 72 year-old, hypertensive woman who arrived at the hospital for pain in the right hypochondrium. General examination revealed an abdomen without signs of peritoneal irr...

Background: Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumors characterized by a high degree of variability and unpredictability. Coexistence of PPGLs and adrenocortical adenomas is an uncommon occurrence that can further complicate the clinical course. Objective: We describe the diagnostic and management challenges of a patient with a history of surgically removed pheochromocytoma, presenting with symptoms of catecholamine exce...

Introduction: Cells of the neuroendocrine system are spread throughout the body, and they can give rise to various neuroendocrine tumors with unpredictable evolution. It has been observed that they are often associated with the development of fibrosis, both local and distant.Case presentation: We present the case of an 81 year-old, normal-weight woman, who firstly presented in our clinic in 2014 for multinodular goiter (normal calcitonin). Fine needle as...

Few cases of CS (and consecutive adrenal insufficiency (AI)) due to intranasal corticoids have been reported and the vast majority were documented in pediatric patients.Case reports: We present two cases of iatrogenic CS due to chronic intranasal administration of over-...
