Article Synopsis
  • Kürsteiner canals (KC) are embryological remnants linked to parathyroid and thymic development, with ongoing research aimed at understanding their role in various parathyroid lesions and cysts.
  • A study evaluated 62 cystic and 22 non-cystic parathyroid lesions over a 12-year period, identifying distinct KC phenotypes in relation to the presence of parathyroid hormone (PTH).
  • The findings reveal that KC commonly appear in parathyroids, particularly in non-PTH cysts, and suggest that these manifestations may originate from KC, while PTH-positive cysts are associated with different characteristics.

Two cases of pancreatic neuroendocrine tumors with ectopic ACTH syndrome during their disease course.

Clin J Gastroenterol

April 2024

Department of Medicine and Bioregulatory Science, Graduate School of Medical Sciences, Kyushu University, 3-1-1 Maidashi, Higashi-Ku, Fukuoka, 812-8582, Japan.

Pancreatic neuroendocrine tumors (PanNETs) are rare malignant tumors that occur in the pancreas. They are divided into functioning and non-functioning tumors based on the presence or absence of their specific hormonal hyper-expression symptoms. Adrenocorticotropic hormone (ACTH)-producing PanNETs are rare, functional tumors, and their clinical characteristics and outcomes have not been well reported.
