Topical diagnosis can be severely complicated in patients with primary hyperparathyroidism (PHPT) due to the ectopic placement of parathyroid gland (PTG) formations. We report a clinical case of PHPT in an 84-year-old patient caused by ectopic PTG adenoma located behind the right internal jugular vein at the level of the right submandibular gland. The impossibility of surgery for a long time due to the absence of a topical diagnosis has necessitated conservative treatment was required to get the hypercalcemia under control.

Small-sized (≤2 cm) pancreatic neuroendocrine tumors (PanNETs) are of particular interest as they are often associated with aggressive behavior, with no specific prognostic or progression markers.
Methods: This article describes a clinical case characterized by a progressive growth of nonfunctional PanNET requiring surgical treatment in a patient with a germline mutation, previously not reported in PanNETs.
Purpose: Determining the primary origin of non-organ-confined neuroendocrine tumors (NETs) for accurate diagnosis and management. Neuroendocrine tumors are rare neoplasms with diverse clinical behaviors. Determining their primary origin remains challenging in cases of non-organ-confined NETs.

The current classification of pancreatic neuroendocrine tumors is based on proliferative grading, and guides therapeutic strategies, however, tumors within grades exhibit profound heterogeneity in clinical manifestation and outcome. Manifold studies have highlighted intra-patient differences in tumors at the genetic and transcriptomic levels.
