Introduction: Neuroendocrine neoplasms of unknown primary (NENs-UP) account for 10-13% of all NENs and show different biologic behavior, histologic appearance and clinical outcome.

Introduction: Recent studies suggest that capsule endoscopy (CE) should be implemented in diagnostic work-up in patients suspected to have small bowel (SB) tumors. SB accounts for the primary tumor site in 80%-85% of patients with intestinal neuroendocrine tumors (NET). In 10%-15% of patients diagnosed with metastasized NET, the primary tumor site remains obscure.

Introduction: Neuroendocrine tumors of unknown primary site (NET UPS) are rare and heterogenous tumors with poor prognosis. There is little information available on the treatment and prognosis.

Introduction: The existence of primary lymph node gastrinoma has been proposed but is controversial. We report two cases (Case A - 37-year-old male, Case B - 43-year-old male) of apparent primary lymph node gastrinoma.

Introduction: Recent studies suggest that video capsule endoscopy (CE) should be implemented in diagnostic work-up in patients with suspected small bowel tumors. Small bowel is the primary site in 80%-85% of patients with intestinal neuroendocrine tumors (NET). In 10%-15% of patients diagnosed with metastasized NET, the localization of the primary tumors remains obscure.

Introduction: Primary neuroendocrine tumors (NETs) are rare and often difficult to detect, leading to diagnosis late in their development. Cases in which the primary cannot be located are denoted as CUP-Syndrome.

Introduction: Based on epidemiological data from SEER 1950-1999, 22.4% cases of non-carcinoid second primary tumors have been described in patients diagnosed with neuroendocrine tumors. The incidence of this type of tumors varies, depending on the series assessed.

Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are relatively rare and complex neoplasms that present many clinical challenges. High grade at diagnosis is an adverse prognostic factor

Introduction: Neuroendocrine tumors (NET) arise from a variety of different organs and have a steadily increasing incidence in the last 3 decades. 13% of NETs have unknown primary sites.
